Before Render

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 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

gem 'rails5_before_render'

Warning: Rails 5 only.

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.
