Accessing components in the frontend

You'll sometimes need to access a component from the frontend, often to fetch it's associated model or models.

How it works

Say you defined the following config/components.rb (for more informations on this file, see Components Configuration) :

section :main_menu do
  component :configuration, :form, model_type: 'Configuration'
  component :informations, :crud, model_type: 'Page', namespaced: true
end

Para then defines a method on the Para.components object with the same name as the identifier. So you can call Para.components.configuration to get you :configuration component.

Here's an example usage :

class SomeController < ApplicationController
  def index
    # Get the configuration model
    @configuration = Para.components.configuration.resource
    # Get the pages from the Informations component
    @information_pages = Para.components.informations.resources
  end
end
