Before Render

Introduction

Add a hook like before_filter 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).

Plugin heavily based on Todd Knarr's rails5_before_render which is based on Vladimir Penkin's rails3_before_render which in turn is based on before_filter for Rails 2 by Todd Willey.

Provided methods:

  • before_render
  • prepend_before_render
  • skip_before_render

Installation

gem 'rails6_before_render'

Warning: Rails 6 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.
