Zobi helps you to orchestrate your controller behaviors using the following gems :

• devise
• has_scope
• kaminari
• pundit
• draper

Add it in your Gemfile and run bundle install:

gem 'zobi', '~> 4.0.2' # Rails 4
gem 'zobi', '~> 5.0.0.rc1' # Rails 5

Next, include Zobi module in your controller and set modules you want to include :

extend Zobi
behaviors :inherited, :scoped, :included, :paginated, :controlled_access, :decorated

This module historically use inherited_resources gem, which is now deprecated.

Now it only defines create/update/destroy methods to easily build CRUD backend.

If your controller is namespaced, you should define the zobi_resource_name method to override its generic behavior.

If your model is namespaced, you should define the zobi_resource_class:

def zobi_resource_class
  ::User::Address`
end

This module also deals with Strong Parameters using Parameters classes.

A Parameters inherits from Zobi::ParametersSanitizer, and should define the list of parameters and nested parameters to accept.

Here is an example :

module User
  class AddressParameters < Zobi::ParametersSanitizer

    # Optional, usefull for a namespaced controller, User::AddressesController
    # here.
    def resource_type
      :user_address
    end

    protected

    def fields
      [
        :id,
        :street,
        :zip_code,
        nested_attributes: [:id, :foo, :bar]
      ]
    end
  end
end

By default, Parameters class are discovered using the controller namespace. Given a User::AddressesController, Zobi will search for User::AddressParameters class.

If you don't want to use Parameters class, you can define the permitted_params in your controller and perform custom filtering.

This module uses has_scope gem.

This module only works with ActiveRecord because it uses the Eager Loading Associations of Active Record.

You just need to define a method named includes and add the associations to load.

def includes
  [:association]
end

This module uses kaminari gem.

This module uses pundit and devise gems.

This module uses draper gem and has a dependency on Inherited modules for now.

By default, Zobi will try to discover the decorator class to use using the current namespece.

For example, given a controller named Admin::User::AddressesController, Zobi will try to find the appropriate decorator class in this order :

Collection :

Admin::User::AddressesDecorator
Admin::AddressesDecorator
AdressesDecorator
Admin::User::CollectionDecorator
Admin::CollectionDecorator
CollectionDecorator

Resource :

Admin::User::AddressDecorator
Admin::AddressDecorator
AdressDecorator
Admin::User::ResourceDecorator
Admin::ResourceDecorator
ResourceDecorator

If this is not the way you organize your decorators, you can override this behavior by defining a method called collection_decorator_class or decorator_class which returns the decorator class to use.

Launch test suite :

cd spec/dummy
bundle exec rake db:test:prepare
cd ../..
bundle exec rspec

Launch the dummy app :

cd spec/dummy
bundle exec rake db:migrate
bundle exec rails s

We decided to follow rails versions to simplify update of Zobi when you want to upgrade rails.
