    Active Admin and Git Challenge

Let's create a demo app Rails 5 app using Active Admin. We can also practice using git along the way.

Create a new Rails app.
Initialize the Rails app folder as a git repository.
Add and commit the existing Rails app files/folders to your git repo.
Create a new git branch called adding_models
Generate a Category model: rails g model Category name:string
Add and commit using git.
Generate a Product model: rails g model Product name:string price:decimal category:references
Ensure that the belongs_to and has_many declarations are present in the Product and Cateogory model classes.
Run your db migrations.
Add and commit using git.
Checkout your master git branch and git in your adding_models branch.
Create a new git branch called adding_activeadmin
Edit the Gemfile to add the following


gem 'inherited_resources', git: 'https://github.com/activeadmin/inherited_resources'
gem 'activeadmin', git: 'https://github.com/activeadmin/activeadmin'
gem 'devise'


Run: bundle install
Run: rails g active_admin:install
Run: rails g active_admin:resource Product
Run: rails g active_admin:resource Category
Edit the product.rb and category.rb files in the app/admin folder to permit all columns to be editable from active admin. (Don't forget the category_id column for the product.)
Run: rails db:migrate
Run: rails db:seed
Run: rails s -b 0.0.0.0
Try loading http://localhost:3000/admin and logging in as admin@example.com with a password of password.
Add two categories using the admin dashboard.
Add three products assigning each one a category.
If everything was successfull, kill server and switch back to the master branch. Merge in the adding_models changes.
Create a remote repository on github and link it to your local git repo.
Push your local repo to the github repo.
Submit a zip of your repo to the dropbox and sumbit the github repo URL in the dropbox comment textarea.
