CREATE AN APP
1.a
laravel new APPNAME
1.b: or:
composer create-project laravel/laravel APPNAME
cmd:
cd name-of-your-project
php artisan -v
(it gives you laravel version)
node -v
npm -v
php -v
laravel -v
(they give version infos)
How do I know which laravel version I use?

Start GIT:
git init
//
git add .
or
git add -A
or
git add --all
git commit -m ("make a commit")
Go to github.com AND make a repo there. Important.
(Don't do a readme yet)
…or push an existing repository from the command line:
cmd:
git remote add origin https://github.com/user/repo.git
or if you want to share/upload a gist:
git remote add origin https://gist.github.com/Bazsmagister/manynumbers
git push -u origin master
(if git error - Fatal: remote origin already exists:)
git remote remove origin
live example:
a:
git remote add origin https://github.com/Bazsmagister/Kindergarten.git
git push -u origin master
b:
git remote add origin https://github.com/Bazsmagister/5.7_with_telescope.git
git push -u origin master
(The -u tells Git to remember the parameters, so that next time we can simply run git push and Git will know what to do.)
Backwards : git pull origin master
USING GIT IN DAILY WORKFLOW
git add *
or if you are in your app directory
git add .
git commit -m "Commit message"
git push
NICE gitlog
git log --graph --oneline --decorate --all
Laravel uses the utf8mb4 character set by default, which includes support for storing "emojis" in the database.
If you are running a version of MySQL older than the 5.7.7 release or MariaDB older than the 10.2.2 release, you may need to manually configure the default string length generated by migrations in order for MySQL to create indexes for them.
You may configure this by calling the Schema::defaultStringLength method within your AppServiceProvider:
Copy into App/Providers/AppServiceProvider:
use Illuminate\Support\Facades\Schema;
public function boot()
{
Schema::defaultStringLength(191);
}
MYSQL
CREATE DATABAE databasename;
USE databasename;
show tables; (empty yet)
In .env file set up DB name and password . Save it!
Not so important
app/conf database.php overwrite.
//'charset' => 'utf8mb4',
//'collation' => 'utf8mb4_unicode_ci',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
2. Laravel telescope:
https://laravel.com/docs/5.7/telescope
If you plan to only use Telescope to assist your local development. You may install Telescope using the --dev flag:
composer require laravel/telescope --dev
or this one:
composer require laravel/telescope
php artisan telescope:install
//it creates a TelescopeServiceProvider and
//it puts App\Providers\TelescopeServiceProvider::class, in app.php
php artisan migrate
php artisan serve
CLick on the URL and add /telescope
When updating Telescope, you should re-publish Telescope's assets:
php artisan telescope:publish
Done.
5. Make model :
php artisan help make:model
php artisan make:model -a Product
(It makes: factory, migration és resource too. -a means all.)
(Model created successfully.
Factory created successfully.
Created Migration: 2020_03_01_100234_create_students_table
Seeder created successfully.
Controller created successfully.)
php artisan make:model -a Destination
(Model created successfully.
Factory created successfully.
Created Migration: 2018_02_17_120444_create_destinations_table
Controller created successfully.)
(vagy:
php artisan make:model --factory Model (it makes factory)
pl:
php artisan make:model --factory Link
php artisan make:model -m SingularCapitalized
(it creates Model and Migration).
php artisan make:model -cfm Destination (it makes controller, factory, migration))
--all -a Generate a migration, factory, and resource controller for the model.
--controller -c Create a new controller for the model.
--factory -f Create a new factory for the model.
--force Create the class even if the model already exists.
--migration -m Create a new migration file for the model.
--pivot -p Indicates if the generated model should be a custom intermediate table model.
--resource -r Indicates if the generated controller should be a resource controller.
//doc
php artisan make:controller PhotoController --resource
Next, you may register a resourceful route to the controller:
in web.php
Route::resource('photos', 'PhotoController');
## Partial Resource Routes
When declaring a resource route, you may specify a subset of actions the controller should handle instead of the full set of default actions
Route::resource('photos', 'PhotoController')->only([
'index', 'show'
]);
Route::resource('photos', 'PhotoController')->except([
'create', 'store', 'update', 'destroy'
]);
Migration file:
/database/migrations there will be the plural lowercase tablename
Moidify it as your own needsn
php artisan migrate;
(Important, that the database need to be empty.)
(Before it you should repair AppServiceProvider if needed)
Table is created in database.
In Models if you don't want to use timestamps:
public $timestamps = false;
Make Controller:
this works not well:
//php artisan make:controller -mr Modellname ModellnameController
it makes Model and Controller also.
it is better:
php artisan make:controller -rm Destination DestinationController
(ez megcsinálja az összes crud metódust is. és hozzáadja a model classt a Controllerhez.
It makes all the CRUD methods and gives the Model class and the Controlller class also.
php artisan make:controller -m Address AddressController
kontroller mögé -r adva megcsinálja a restful metódusokat is.
Adding -r after the Controller it makes the resful methods also.
Route::resource('students', 'StudentsController');
Route::resource('addresses', 'AddressController');
Making factory:
php artisan make:factory AddressFactory
php artisan make:factory StudentFactory
FAKER MAKING:
https://github.com/fzaninotto/Faker/blob/master/src/Faker/Provider/hu_HU/Address.php
USING faker in other language f.e (hungarian) :
In Config/app.php Faker Locale
'faker_locale' => 'hu_HU',
Faker timestamps:
https://github.com/fzaninotto/Faker#fakerproviderdatetime
'created_at'=> $faker->dateTimeBetween($startDate = '-5 years', $endDate = '-3 years', $timezone = null),
'updated_at'=> $faker->dateTimeBetween($startDate = '-2 years', $endDate = 'now', $timezone = null),
'customer_id' => $faker->unique()->randomElement($array = array ('1','2','3','4','5','6','7','8','9','10'), $count = 1),
THEN IN
Database/Factories/ UserFactory :
$factory->define(App\Wordchain::class, function (Faker $faker) {
return [
'words' => $faker->name,
'wordsstringben' => str_random(10),
'updated_at'=> $faker->NOW(),
];
SEEDER MAKING
php artisan make:seeder StudentTableSeeder
php artisan make:seeder ProductTableSeeder
php artisan make:seeder Destination_ProductTableSeeder
php artisan make:seeder UsersTableSeeder
INTO THE run method or
in
php artisan tinker:
factory(App\Student::class, 10)->create();
factory(App\User::class, 20)->create();
\App\User::create(["name" =>"admin", "email" => "admin@admin.com", "password" => bcrypt("password")]);
\App\User::create(["name" =>"admin2", "email" => "admin2@admin.com", "password" => bcrypt("password2")]);
in tinker also:
//this way we don't have to use App\User::create(....)
namespace = App;
$user3 = User::create(['name' => 'user3', 'email' => 'user3@exapmle.com', 'password' => bcrypt('password3')]);
php artisan make:seeder AddressTableSeeder
ebbe a run metódusba:
factory(App\Address::class, 10)->create();
IMPORTANT:
use App\Product;
use App\ANYModel
Database\seed\Databaseseeder run method :
$this->call([
UsersTableSeeder::class,
AddressTableSeeder::class,
StudentTableSeeder::class,
]);
Once you have written your seeder, you may need to regenerate Composer's autoloader using the dump-autoload command:
composer dump-autoload
Make pivot to many to many
This is how I create pivot tables in Laravel 5 with foreign key constraints:
//php artisan make:migration create_player_team_table --table=player_team
//php artisan make:migration create_destination_product_table --table=destination_product
//php artisan make:migration create_destination_product_pivot_table --table=destination_product
good ones:
php artisan make:migration create_destination_product_pivot_table --create=destination_product
php artisan make:migration create_hero_spell_pivot_table --create=hero_spell
So it will be good the migration file inside.
Pivot table making:
php artisan make:migration --create address_student create_address_student_pivot_table
php artisan make:migration --create destination_product create_destination_product_pivot_table
php artisan make:migration --create bicycle_user create_bicycle_user_pivot_table
Note: in case you have timestamps on the pivot table you must set withTimestamps on the relationship of both ends like this:
return $this->belongsToMany(\Mega\Modules\Account\Models\Tag::class)->withTimestamps();
return $this->belongsToMany(\Mega\Modules\Account\Models\Account::class)->withTimestamps();
php artisan migrate:refresh;
php artisan db:seed;
or:
php artisan db:seed --class=UsersTableSeeder
best :
php artisan migrate:fresh --seed
You may also seed your database using the migrate:refresh command, which will also rollback and re-run all of your migrations. This command is useful for completely re-building your database:
php artisan migrate:refresh --seed (erase database, but doesn't drop tables.)
php artisan migrate:fresh --seed (a fresh new migration. it drops tables too. (From 5.5).
OR:
7. php artisan tinker
factory('App\Wordchain', 50)->create();
It creates 50 fake, and it will be in the database.
8.
in routes/web
Route::resource('Wordchain', 'WordchainConroller');
php artisan route:list
/it gives all the routes list
9. Then in WordchainController:
public function index()
{
$wordchain = Wordchain::all();
return view('wordchain.index', ['wordchains' => $wordchain]);}
10.resources\views\wordchains(én készítettem)\index.blade.php make and edit.
11. php artisan serve
12.in a brower http://localhost:8000/Wordchain
13.comment out in blade:
{{-- and end with --}}
14. PAGINATION
in the Controller : ->simplePaginate(5);
don't use get:get()
if there is orberBy then it will not work.
in View : <?php echo $products->render(); ?>
or
<div class=" d-flex justify-content-center pt-2">
{{ $products->links() }}
</div>
Second way :
php artisan make:controller LearnController --resource;
$users = DB::table('sizes')
->crossJoin('colours')
->get();
Teszt:
run:
in cli :
.vendor/bin/phpunit
or
./vendor/bin/phpunit
vscodeban phpunit setup:
C:\Users\User\AppData\Roaming\Composer\vendor\bin\phpunit.bat
"./phpunit.xml.dist"

<link href="{{ asset('css/album.css') }}" rel="stylesheet">
//For n:m Relationships, where I need to attach random entries, I use this simple but efficient Seeder code, that only uses real ids:

USEFUL COMMANDS:
php artisan cache:clear
php artisan view:clear
php artisan config:clear
php artisan route:clear

alias paclear='php artisan view:clear && php artisan cache:clear && php artisan config:clear && php artisan route:clear'
answer:
Compiled views cleared!
Application cache cleared!
Configuration cache cleared!
Route cache cleared!
Clear the config cache php artisan config:clear or rebuild it php artisan config:cache.
AUTH and Frontend scaffolding:
in laravel 6:
php artisan make:auth; => it makes a login page. i
in laravel 7 :
composer require laravel/ui
Front end scaffolding:
//in Laravel 7
composer require laravel/ui
//before laravel 8 it worked.
In 2020 12 there was a failure:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- laravel/ui[v3.1.0, ..., 3.x-dev] require illuminate/console ^8.0 -> found illuminate/console[v8.0.0, ..., 8.x-dev] but it conflicts with another require.
- Root composer.json requires laravel/ui ^3.1 -> satisfiable by laravel/ui[v3.1.0, 3.x-dev].
solution:
composer require laravel/ui "^2.0"
//in Laravel 6
composer require laravel/ui:^1.0 --dev
php artisan ui bootstrap --auth
npm install && npm run dev
then:
php artisan ui vue --auth
or
php artisan ui react --auth
or
php artisan ui bootstrap --auth
--auth is not necessary, just in case you need authentication
npm install && npm run dev
npm install
npm run dev
npm run watch
You may find that in certain environments Webpack isn't updating when your files change. If this is the case on your system, consider using the watch-poll command:
npm run watch-poll
Creating Applications Including Authentication
If you are starting a brand new application and would like to include the authentication scaffolding, you may use the --auth directive when creating your application. This command will create a new application with all of the authentication scaffolding compiled and installed:
laravel new blog --auth
How to downgrade Laravel?
The best way to do this is by changing the value of the Laravel version inside the composer.json file to the laravel 5.5.
delete vendor folder and run composer install
or:
composer create-project --prefer-dist laravel/laravel PROJECTNAME "6.*"
>composer create-project --prefer-dist laravel/laravel Projectname "7.*"
prefer-dist :
--prefer-dist: Reverse of --prefer-source, Composer will install from dist if possible. This can speed up installs substantially on build servers and other use cases where you typically do not run updates of the vendors. It is also a way to circumvent problems with git if you do not have a proper setup.
prefer-source:
--prefer-source: There are two ways of downloading a package: source and dist. For stable versions Composer will use the dist by default. The source is a version control repository. If --prefer-source is enabled, Composer will install from source if there is one. This is useful if you want to make a bugfix to a project and get a local git clone of the dependency directly.
Using sqlite
in .env file
DB_CONNECTION=sqlite
?? DB_DATABASE=database/database.sqlite
and make an sqlite database
touch database/database.sqlite
php artisan migrate:fresh
error:
What happens if you remove the DB_DATABASE from your .env file and use the default in config/database.php which is
'database' => env('DB_DATABASE', database_path('database.sqlite')),
Restart server!!!
In vscode : ctrl+shift+p (commands)

open sqlite database (and it is not working :) )
TINKER
factory('App\User', 10)->create();
App\User::all()
App\User::first()
php artisan make:seeder UserSeeder
//Many to many
User::first()->roles()->attach(3);
return User::first();
return User::with('roles')->first();
return User::first()->roles;
return User::first()->roles->first();
return User::first()->roles->first()->name;
Before and Role using
Route::get(/reporting, function(){
return 'secret financial data';
})->before(role:admin);
after that we should make a filter...Route::filter where csrf filter is.
https://github.com/laracasts/Users-and-Roles-in-Laravel/blob/master/app/filters.php
Route::filter('role', function($route, $request, $role)
{
if (Auth::guest() or ! Auth::user()->hasRole($role))
{
App::abort(403);
}
}); 4years ago...
Route::get('/reports', function () {
return 'the secret reports';
})->middleware('can:view_reports');
Auth::loginUsingId(1);
auth()->loginUsingId(11);
Dependency / dependecies:
if you're not a Windows user you can drop cross-env.
Note: if you drop the cross-env dependency, you also have to remove the string "cross-env " from the beginning of each of the scripts lines (e.g. cross-env NODE_ENV=... becomes NODE_ENV=...).
it shows the sql command for the query:
DB::listen(function($query) {var_dump($query->sql, $query->bindings); });
In User Model. It makes the query in Laracasts Laravel 6 from scratch ep.60. It makes the query not by id but by 'name'.
public function getRouteKeyName{
return 'name';
}
<p> Joined {{$user->created_at->diffForHumans() }} </p>
in blade:
@component('master')
//if you have a componentS dir in wievs. Laravel 7.
In laravel 7 also you can use:
<x-master> </x-master>
from Laravel docs:
Often, you will need to pass additional content to your component via "slots". Let's imagine that an alert component we created has the following markup:
<!-- /resources/views/components/alert.blade.php -->
<div class="alert alert-danger">
{{ $slot }}
</div>
We may pass content to the slot by injecting content into the component:
<x-alert>
<strong>Whoops!</strong> Something went wrong!
</x-alert>
The major difference is that Laravel's users table migration out the box changed from $table->increments('id'); to $table->bigIncrements('id'); in Laravel 5.8.
php artisan vendor:publish --tag=anypackage

php artisan vendor:publish --provider="Encore\Admin\AdminServiceProvider"

Stub Customization
php artisan stub:publish
The Artisan console's make commands are used to create a variety of classes, such as controllers, jobs, migrations, and tests. These classes are generated using "stub" files that are populated with values based on your input. However, you may sometimes wish to make small changes to files generated by Artisan. To accomplish this, you may use the stub:publish command to publish the most common stubs for customization:
The published stubs will be located within a stubs directory in the root of your application. Any changes you make to these stubs will be reflected when you generate their corresponding classes using Artisan make commands.
## php artisan storage:link
The [/home/bazs/code/bicycle_7.7.1/public/storage] link has been connected to [/home/bazs/code/bicycle_7.7.1/storage/app/public].
The links have been created.

Middleware auth
or method chaining in .web file ->auth()
or in Controller in the __construct method:
public function __construct()
{
$this->middleware('auth');
}
in blade file
@if (Auth::user()){
Hi {{Auth::user()->name}}
}
@else {
default
}
@endif
or (both is the same)
@if (Auth::check()){
Hi {{Auth::user()->name}}
}
@else{
default
}
@endif
Same:
@auth {
Hi {{Auth::user()->name}}
}
@else {
default
}
@endauth
The opposite of @auth is @guest
@guest {
}
@else {
}
@endguest
Carbon:
use Carbon\Carbon
Add the following line to the aliases array in the config/app.php:
'Carbon' => 'Carbon\Carbon'
And you need to add use Carbon; every class where you want to use it.
You can declare some fields in your models using the following structure:
protected $dates = ['created_at', 'updated_at', 'disabled_at','mydate'];
All of those fields will automatically be Carbon instances and you will be able to use them in your views like:
{{ $article->mydate->diffForHumans() }}
Single Action Controllers:
php artisan make:controller ShowProfile --invokable
Error:
undefined variable id laravel
answe from SO:
just pass the $id to your Update method:
public function update(Request $request, $id)
but you have to make sure your route has {id} segment in your routes file
IF, Unless
@if (! in_array($currentVersion, [DEFAULT_VERSION, 'master']))
@unless (in_array($currentVersion, [DEFAULT_VERSION, 'master']))

doctrine/dbal
dbal = database absraction layer.
doctrine : The Doctrine Project is the home to several PHP libraries primarily focused on database storage and object mapping.
Laravel 5 now supports changing a column; here's an example from the offical documentation:
$table->text('excerpt')->nullable()->change(); ???
Before modifying a column, be sure to add the doctrine/dbal dependency to your composer.json file. The Doctrine DBAL library is used to determine the current state of the column and create the SQL queries needed to make the required adjustments:
Laravel 7 doc
$table->nullableTimestamps(0); Alias of timestamps() method.
$table->softDeletes('deleted_at', 0); Adds a nullable deleted_at TIMESTAMP equivalent column for soft deletes with precision (total digits).
$table->softDeletesTz('deleted_at', 0); Adds a nullable deleted_at TIMESTAMP (with timezone) equivalent column for soft deletes with precision (total digits).
Psalm
Psalm is an open-source static analysis tool for PHP that helps you identify both obvious and hard-to-spot bugs in your code.
https://psalm.dev/schema/config
psalm.xml in vendor files.
Soft Deletes:
in migration table:
$table->softDeletes();
$table->timestamps();
In model:
use SoftDeletes;
protected $dates = ['deleted_at'];
protected $table = 'estados';
protected $casts = ['id' => 'string', 'pais_id' => 'string'];
protected $primaryKey = ['id', 'pais_id']; //
protected $fillable=[
'id', 'pais_id', 'estado',
];
https://laravel.com/docs/7.x/eloquent-mutators
Route::get('/clear-cache', function() {
$configCache = Artisan::call('config:cache');
$clearCache = Artisan::call('cache:clear');
// return what you want
});
# Timezone:
in config\app.php
'timezone' => env('APP_TIMEZONE', 'UTC'),
in .env
APP_TIMEZONE=Europe/Budapest
In order to use users timezone, first that timezone needs to be stored somewhere
for example in DB table users under column timezone
and then if you need the current time in users timezone you just call this method:
$usersCurrentTime = now($user->timezone)->format('Y-m-d H:i:s');
That will give you the current time in users timezone.

# Variable handling Functions
drop the dd() and use print_r() instead due to the Laravel lifecycle
print_r() displays information about a variable in a way that's readable by humans.

# Middleware
# Auth
If you want to add that extra middleware in the route. Just use the group and you'll be fine.
Route::group(['middleware' => 'auth'], function () {
// User needs to be authenticated to enter here.
Route::get('/', function () {
// Uses Auth Middleware
});
Route::get('user/profile', function () {
// Uses Auth Middleware

});
# Truncate
If you wish to truncate the entire table, which will remove all rows and reset the auto-incrementing ID to zero, you may use the truncate method:
DB::table('users')->truncate();
Visitor::query()->truncate();
Visitor::truncate();
# manyToMany
// $admin->role()->attach($adminRole);
// $author->role()->attach($authorRole);
// $user->role()->attach($userRole);
# DB::listen
DB::listen(function($query) {var_dump($query->sql, $query->bindings); });

# uuid
A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. The term globally unique identifier (GUID) is also used, typically in software created by Microsoft.
123e4567-e89b-12d3-a456-426614174000
xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx
You may want to set
protected $keyType = 'string';
so Laravel handles joins as strings and doesn’t cast to integer.
OPTIONAL: If you changed the field name in your migrations, you must set
protected $primaryKey = 'uuid';
to match.
Usually for UUID you will also set
public $incrementing = false;
.Remove it if it causes problems for you.

and simple in your method just call this:

# MYSQL Varchar and text
The string() method creates a VARCHAR equivalent column while text() creates a TEXTequivalent. With that done, let’s go ahead and migrate:
HTTP codes:
200: OK. The standard success code and default option.
201: Object created. Useful for the store actions.
204: No content. When an action was executed successfully, but there is no content to return.
206: Partial content. Useful when you have to return a paginated list of resources.
400: Bad request. The standard option for requests that fail to pass validation.
401: Unauthorized. The user needs to be authenticated.
403: Forbidden. The user is authenticated, but does not have the permissions to perform an action.
404: Not found. This will be returned automatically by Laravel when the resource is not found.
500: Internal server error. Ideally you're not going to be explicitly returning this, but if something unexpected breaks, this is what your user is going to receive.
503: Service unavailable. Pretty self explanatory, but also another code that is not going to be returned explicitly by the application.

An alternate solution is adding this to the links key in your config/filesystems.php file.
public_path('avatars') => storage_path('app/public/avatars'),
After adding that, then you can run the artisan command again, and it should work.
For the avatar validation, you can use the image rule instead of just file. The dimensions rule maybe be useful as well. Example:
'avatar' => [
'image',
'dimensions:min_width=100,min_height=200',
],
<div class="mb-6">
<label class="block mb-2 uppercase font-bold text-xs text-grey-700" for="name">

question:
hi i want to update one of my tables with the new data i post to my controller is there a way to do some thing like
Platform::update($request->all());
my post request is like this
axios.post(`http://www.crown.mehi/admin/platforms`, { data })
.then(res => {
console.log(res);
console.log(res.data);
})
i changed the data inside of json request and i want to update my table in database with it
public function store(Request $request)
{
dd($request->all);
Platform::update($request->all());
}
answer
So the solution for the problem was this:
public function updateOrder(Request $request)
{
foreach ($request['data'] as $entry) {
Platform::where('id', $entry['id'])->update(['order' => $entry['order']]);
}
}
You have to go through all of the sent items and update them.
'bicycle_id' => \App\Bicycle::all()->random()->id,
'user_id' => \App\User::all()->random()->id,
$maxValue = App\User::max('id');
dd($maxValue);
Public function search(){
$pageName = 'your page name';
$error = 'something went wrong';
return view('yourview')->with([
'page_title'=> $pageName,
'error'=> $errorMesssage
]);
}
Now you can access those variable in your blade file as
{{$page_title}}
{{$error}}
Try to use {!! $data->render() !!} instead of {!! $data->links() !!}
# strtotime
$dateStart = date('Y-m-d', strtotime('-5 year'));
$dateEnd = date('Y-m-d');
#php ini
echo php_ini_loaded_file();
# bash function
function acp(){
git add --all;
git commit -m "$1";
git push;
}
# Collection vs 1 object:
When you're using get() you get a collection. In this case you need to iterate over it to get properties:
@foreach ($collection as $object)
{{ $object->title }}
@endforeach
Or you could just get one of objects by it's index:
{{ $collection[0]->title }}
Or get first object from collection:
{{ $collection->first() }}
When you're using find() or first() you get an object, so you can get properties with simple:
{{ $object->title }}
# File Storage example:
public function store(Request $request) {
$blob = $request->file('record_audio');
$filename = $blob->getClientOriginalName() . date("now") . ".ogg";
$localization = 'files/' . $filename;
Storage::put($localization, file_get_contents($blob));
}
# migartion tipps
$table->string('PASSWORD', 500);
$table->string('profileImage', 500)->default(null);
$table->boolean('admin')->default('0');
$table->time('created_At')->nullable()->useCurrent();

php artisan stub:publish
The published stubs will be located within a stubs directory in the root of your application. Any changes you make to these stubs will be reflected when you generate their corresponding classes using Artisan make commands.

# In the shell, what does “ 2>&1 ” mean?
File descriptor 1 is the standard output (stdout).
File descriptor 2 is the standard error (stderr).
Here is one way to remember this construct (although it is not entirely accurate): at first, 2>1 may look like a good way to redirect stderr to stdout. However, it will actually be interpreted as "redirect stderr to a file named 1". & indicates that what follows is a file descriptor and not a filename. So the construct becomes: 2>&1.
Directory Separator:
Because in different OS there is different directory separator. In Windows it's \ in Linux it's /. DIRECTORY_SEPARATOR is constant with that OS directory separator. Use it every time in paths.

});
public function logout(Request $request)
{
Auth::user()->tokens()->where('id', Auth::user()->currentAccessToken()->id)->delete();
return response()->json(['data' => 'User logged out.'], 200);
}
#
$client = new Client();
$res = $client->request('POST', 'http://127.0.0.1:5000', [ 'form_params' => $data ]);
if ($res->getStatusCode() == 200)

//return $response_data;;
dd($response_data);
// $data = gettype($response_data);
// dd($data);
//View
return view('front.flight-list', compact('response_data'));
}
to convert your JSON string response to a JSON object you can work with. You an also do something like $response_data = collect(json_decode($res->getBody(), true)); to make it into a laravel collection as well

# Get specific columns in json
You can use select for certain field display :
Model::select('title', 'price', 'description')->get();
Or, in get() method :
Model::get(['title', 'price', 'description']);
As you would like to make some typically visible attributes hidden on a given model instance, you may use the makeHidden method :
$data = Model::all();
$data->makeHidden('price');
Now price will be hidden from your query.

withTimestamps(); is used in Many to Many relationships where you want to declare that there are created_at and updated_at columns in the join table.
$withTimestamps Indicates if timestamps are available on the pivot table.
As the exception rightly points out, Illuminate\Database\Eloquent\Relations\HasMany does not have a withTimestamps() method.
## Important !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
https://laracasts.com/discuss/channels/laravel/undefined-property-stdclassuser:
If you want to get the User through the defined relationship, then you will need to use the Eloquent model to fetch the $history; using the DB class bypasses Eloquent, and therefore, the relationship. Try this instead:
$history = Adjustments::with('user')
->where('remark_id', $operation->id)

laravel/scout suggests installing algolia/algoliasearch-client-php (Required to use the Algolia engine (^2.2).)
composer require algolia/algoliasearch-client-php
2.7
Finally, add the Laravel\Scout\Searchable trait to the model you would like to make searchable. This trait will register a model observer to keep the model in sync with your search driver:
use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;
class Post extends Model
{
use Searchable;
}
algolia need id...
i try an other engine:

Next add the ServiceProvider to the Package Service Providers in config/app.php
/*
* Package Service Providers...
*/
Yab\MySQLScout\Providers\MySQLScoutServiceProvider::class,
Append the default configuration to config/scout.php
'mysql' => [

'min_search_length' => 0,
'min_fulltext_search_length' => 4,
'min_fulltext_search_fallback' => 'LIKE',
'query_expansion' => false
]
Set SCOUT_DRIVER=mysql in your .env file
<!-- php artisan scout:import -->
php artisan scout:mysql-index App\\Hero

spatielaravel-permissions 3.16
composer require spatie/laravel-permission
https://spatie.be/docs/laravel-permission/v3/installation-laravel
In the Installation instructions you'll see that the HasRoles trait must be added to the User model to enable this package's features.
use Illuminate\Foundation\Auth\User as Authenticatable;
use Spatie\Permission\Traits\HasRoles;
class User extends Authenticatable
{
use HasRoles;
// ...
}
in config/app.php add:
Spatie\Permission\PermissionServiceProvider::class,
php artisan vendor:publish --provider="Spatie\Permission\PermissionServiceProvider"
php artisan optimize:clear
php artisan migrate
php artisan make:seeder RolesAndPermissionsSeeder
in that seeder class:
$role = Role::create(['name' => 'admin']);
$role->givePermissionTo(Permission::all());
$admin = factory(\App\User::class)->create([
'id' => '1',
'name' => 'Admin Adam',
'email' => 'admin@admin.com',
'password' => bcrypt('adminadmin'),
'phone' => '0623232565321',
]);
$admin ->assignRole('admin');
$authuser = factory(\App\User::class)->create([
'id' => '2',
'name' => 'Authenticated User',
'email' => 'authuser@authuser.com',
'password' => bcrypt('authuser'),
'phone' => '0623232565322',
]);
$authuser ->assignRole('authuser');

ls database/migrations | wc -l
(wordcount -line)
There is no factory method anymore.
App\Models\User::factory()->make();
//dont persist in the database
App\Models\User::factory()->count(3)->make();
persist in the database.
App\Models\User::factory()->count(3)->create();
---
App\Models\User::factory()->has(Post::factory->count(5)->create();
This one needs the User model has posts().
posts(){
return \$this->hasMany(Post::class);
}
---
a lesser verbose with magic method:
App\Models\User::factory()->hasPosts(5)->create();
--
reverse of it:
Post::factory()->for(User::factory)->count(3)->create();
This one still needs a relationship.
public functon user(){
return \$this->belongsTo(User::class);
}
a lesser verbose:
Post::factory()->forUser()->count(3)->create();

php artisan down --secret=asecretword
so localhost/asecretword will work. It put a cookie on the machine.
published: php artisa publish 12
php artisan down --render="errors.illustrated-layout"
php artisan down --render="errors::503"

When you generate your factory with php artisan make:factory in Laravel 8, you need to update:
use App\Models\Model;
class ModelFactory
protected $model = Model::class;
In your case, you would have to replace Model with Article:
use App\Models\Article;
class ArticleFactory
protected $model = Article::class;
An easier option would have been to run php artisan make:factory --model=Article from the start. Everything would have been properly filled to be used for an Article model. Then, only the definition method would have needed to be edited.

Spatie\Permission\Exceptions\GuardDoesNotMatch
The given role or permission should use guard `` instead of `web`.
solution: //in User.php
protected $guard_name = 'web';
---
class App\User not found whn i want to login.
solution: config/auth.php 'model' => App\Models\User::class,

$attributes contains the current version of model's attributes. $original is supposed to contain, well, the original values of given object, so here you'll find the values that object was created with or the values it was loaded with from the database.

Download xdebug-2.9.8.tgz
Install the pre-requisites for compiling PHP extensions.
On your Ubuntu system, install them with:
sudo apt install php-dev autoconf automake
Unpack the downloaded file with tar -xvzf xdebug-2.9.8.tgz
Run: cd xdebug-2.9.8
Run: phpize (See the FAQ if you don't have phpize).
The phpize command is used to prepare the build environment for a PHP extension.
As part of its output it should show:
Configuring for:
...
Zend Module Api No: 20190902
Zend Extension Api No: 320190902
If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.
Run: ./configure
Run: make
Run: cp modules/xdebug.so /usr/lib/php/20190902
Edit /etc/php/7.4/cli/php.ini and add the line
zend_extension = /usr/lib/php/20190902/xdebug.so
Make sure that zend_extension = /usr/lib/php/20190902/xdebug.so is below the line for OPcache.
Please also update php.ini files in adjacent directories, as your system seems to be configured with a separate php.ini file for the web server and command line.
Restart the webserver
in php ini:
[XDEBUG]
xdebug.remote_enable=1
xdebug.remote_autostart=1

text, longtext
It's based on what type of content you're expecting from the user Text has the capacity to hold 65,535 characters which is about 64 KiB of size while LONG TEXT has the capacity to hold 4,294,967,295 characters which is about 4GB of size.
For me I use TEXT.
Hope it's helpful.

php artisan make:controller --model=Video VideoController
php artisan make:controller --invokable CreateVideoController
Resource:
php artisan make:controller --model=Video --resource VideoController
API:
php artisan make:controller --model=Video --api VideoController
Route::apiResource() only creates routes for index, store, show, update and destroy while
Route::resource() also adds a create and edit route which don't make sense in an API context.
---
Interesting. Route::get /anything here gives back a view.
Route::get('/{any}', function () {
return view('vueapp');
})->where('any', '.*');

Cannot create cache directory .. or directory is not writable. Proceeding without cache in Laravel:
solution:
Change the group permission for the folder
sudo chown -R w3cert /home/w3cert/.composer/cache/repo/https---packagist.org
and the Files folder too
sudo chown -R w3cert /home/w3cert/.composer/cache/files/
I'm assuming w3cert is your username, if not change the 4th parameter to your username.
If the problem still persists try
sudo chown -R w3cert /home/w3cert/.composer
I've encountered this a couple of times, but just realised that this may be a consequence of running self-update as root: $ sudo composer self-update , which may have been the cause of why the ~/.composer folder and all its contents change owner. Just chown -R your ~/.composer back to yourself

npm, js, vue, laravel-mix
failure:
[webpack-cli] Error: Unknown option '--hide-modules'
[webpack-cli] Run 'webpack --help' to see available commands and options
https://github.com/JeffreyWay/laravel-mix/issues/2523
solution:
JeffreyWay's answer:
Remove those two options from your build script in package.json. Webpack 5 no longer supports them.
Or use the new Mix executable:
npx mix -p
https://github.com/JeffreyWay/laravel-mix/blob/master/docs/cli.md
(When it comes time to build your assets for a production environment, Mix will set the appropriate webpack options, minify your source code, and optionally version your assets based on your Mix configuration file (webpack.mix.js). To build assets for production, include the --production flag - or the alias -p - to the Mix CLI. Mix will take care of the rest!
npx mix --production)
(laravel-mix 6.doc:
-Support for webpack 5
-New `npx mix` executable for triggering your build
https://github.com/JeffreyWay/laravel-mix/blob/master/docs/installation.md
)
What is difference between NPM and NPX?
Npm is a tool that use to install packages. Npx is a tool that use to execute packages. Packages used by npm are installed globally you have to care about pollution for the long term. Packages used by npx are not installed globally so you have to carefree for the pollution for the long term.

This means your vue and vue-template-compiler dependencies are out of sync. Per Vue 2's instructions, the version number for both of these dependencies must be identical. Update as needed to fix the problem:
solution:
npm update vue
// or
npm install vue@2.5.15 (both need to be identical)
---
I'm having trouble updating/installing Mix.
Unfortunately, there are countless reasons why your dependencies may not be installing properly. A common root relates to an ancient version of Node (node -v) and npm (npm -v) installed. As a first step, visit http://nodejs.org and update those.
Otherwise, often, it's related to a faulty lock file that needs to be deleted. Give this series of commands a try to install everything from scratch:
rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force //npm cache clean no longer works because npm is self healing.
npm install
