Before Render

Introduction

Add a hook like before_action to your controllers that gets executed between when your action is completed and the template is rendered. It can really DRY up loading some data that is used for views (headers / layouts / etc).

Provided methods:

• before_render
• prepend_before_render
• skip_before_render

Installation

gem 'before_render', '~> 0.2', github: 'ishumilova/before_render'

Warning: Ruby 2+, Rails 4 and Rails 5 only.

Usage

before_render / prepend_before_render / skip_before_render works as other filters. Options like :except and :only can be passed to filter.

class PostsController < ApplicationController
  before_render :ping, :except => [:destroy]

  def index; end     

  def new; end

  def show; end

  def destroy; end                                                                          
          
  private
    def ping
      Rails.logger.info "Ping-Pong actions"
    end
end       

Method ping will be executed after your actions and before template is rendered.
