Found an example
there is a thing in laravel called FormRequest
.
Sometimes, I need extra validation. So I need to use some service there somehow. What options I have
- facade
- service locator via app() global function
- I also have instance of container there via
$this->container
which one is the best here? I suppose instance of container
I can't do constructor injection. Why? Because for me, it seams that there are too many arguments on the __construct
method
it look like this
Am I wrong with this one?
Also they (FormRequest
s) help me to make controllers slim.
I get all the extra data there (for example get user by email,
I mean not the current session user, but the one that I, for example, edit)
so I don't need to do this in other place.
what I also can do is to make some separate method, name it, for example, afterValidationRequestDataSetter
,
on the form request, call it at the end of all operations like
$this->container->call([$this, 'afterValidationRequestDataSetter'])
and it will inject all the dependencies that I need
(I suppose, have not tested yet), but that
-
is not constructor injection
-
looks a bit like a magic since you can't do search on who calls this method (especially, it will be hard for new people on the project)
what is your ides about that?
p.s. not laravel zombie-fan and not forcing people to use facades
Also need to mention about views and service providers (see https://laravel.com/docs/5.7/providers)
so I shouldn't use
boot
method on\Illuminate\Support\ServiceProvider
also (it work similar to what I was trying to do withafterValidationRequestDataSetter
) ? If yes, how should I inject dependencies then into service provider?because I can't inject anything into constructor because it resolves it like this https://github.com/laravel/framework/blob/5.7/src/Illuminate/Foundation/Application.php#L636-L639
also sometimes I need services in my views (it was layouts) there are 2 ways to do that
app()
helper function which is bad since service locator is used and in view I only need the end data and even no way to change things via servicewhich one is better?
also is that ok to inject
\Illuminate\Foundation\Application
(which is also a container instance at the same time) into my services?
