Instance Method Details

#use_presenters! ⇒ Object

Overrides AbstractController#view_assigns to return presenters set with the present method.

When you call this method in a controller class, instance variables set in actions will no longer be shared with views.

Examples

# app/controllers/posts_controller.rb
class PostController < ApplicationController
  include Livery::Controler
  use_presenters!

  def show
    @post = Post.find(params[:id])
    present(post_presenter: @post)
  end
end

In this example, the instance variable @post will not be shared with the view. Instead, the present method will create a presenter-wrapped object available as @post_presenter in the view.
