Resourceable

Replaces the need for scaffolded controllers while not restricting the developer.

• CanCanCan - loading and authorizing resource
• Ransack - searching and sorting
• Kaminari - pagination

Add this line to your application's Gemfile:

gem 'resourceable'

Run the installer. Resourceable will also run the installers for Kaminari, CanCan and Responders.

rails g resourceable:install

Replaces the need for scaffolded controller code. You will still need too create the views (for now).

class UsersController < ApplicationController 
  crud permitted: [ # strong params (default to {})
    :email, :password 
    ], 
    cancan: { # cancan options (default is cancan default)
      class_name: User, 
      id_params: :user_id 
    },
    q: :search # ransack url variable (defaults to :q)
end

Strong params can be defined in an instance method named resource_params

class UsersController < ApplicationController 
  crud

  private 

  def resource_params 
    params.require(:user).permit(:email, :password)
  end
end

Any of the regular CRUD actions can be done as one normally would. If you need some custom handling of resource creation, just define it. Resourceable will still handle any actions you haven't defined.

class UsersController < ApplicationController 
  crud permitted: [:email, :password]

  def create 
    if @user.valid?
      @user.save 
      UserMailer.new_user(@user).deliver_now
    else 
      render :new
    end
  end
end

Pagination can be configured through the pagination option. Everything else is just plain Kaminari.

class UsersController < ApplicationController 
  crud pagination: {
      param: :user_page,  # default is :page, 
      per: 10,            # default is 20
    }
end

Resourceable adds a new SimpleForm input of has_many to simplify has_many associations. Resourceable will use the provided partial to display the associated objects. Don't forget to update the permitted params in your controller for the nested attributes.

class Task < ApplicationRecord 
  has_many :details 
  accepts_nested_attributes_for :details
end

class Detail < ApplicationRecord 
  belongs_to :task
end

/ app/views/tasks/_form.slim
= simple_form_for @task do |f|
  = f.input :details, as: :has_many, partial: 'tasks/detail_fields'

/ app/views/tasks/_detail_fields.slim
= form_object.input :body
