ControllerLess

ControllerLess is DSL to DRY controller and Routes using inherited_resources inspired by activeadmin.

Installation

ControllerLess requires ruby 2.* with rails 3.-4. to run.

gem 'controller_less', '~> 0.0.9.pre'

Basic Usage

Initialize the gem by creating file in config/initializers/controller_less.rb, the basic file will look like this.

ControllerLess.setup do
end

You will also need to add this line ControllerLess.load_routes in config/routes.rb.

To use ControllerLess you have to create posts_cls.rb in the app/cls folder.

ControllerLess.register Post do
end

Namespace

To use namespace pass the parameter of namespace to .register method checkbelow for example.

Controller.register Post, namespace: "Api::V1" do
end

Restricting the Routes and Action Created

By default ControllerLess creates seven actions with their routes using inherited_resources. You can restrict the access by passing options to only method. check the exmaple below

Controller.register Post do
    only :index, :show
end

Callbacks

Following methods are delegate to controller.

:respond_to, :_insert_callbacks, :_normalize_callback_options, :after_action, :append_after_action, :append_around_action, :append_before_action, :around_action, :before_action, :prepend_after_action, :prepend_around_action, :prepend_before_action, :skip_action_callback, :skip_after_action, :skip_around_action, :skip_before_action, :skip_filter

How to use the callback in ControllerLess check the example below.

ControllerLess.register User do
    before_action :authenticate_user! 
end

Strong Parameters

ControllerLess works smooth with Strong Parameters to allow the parameters pass the values to permitted_params. Please check the example below.

ControllerLess.register Post do
    permitted_params :title, :create
end

Overriding methods & Add Private methods

You can override method by writing code in controller block. Please the check the example.

ControllerLess.register Post do
    controller do
        def index
            @posts = Post.last(5)
        end
