Installation

Add this line to your application's Gemfile:

gem 'before_actions'

And then execute:

bundle
rails g before_actions:template

Upgrading from 1.*

bundle update before_actions
rails g before_actions:template

Then simply adjust your controllers to the new syntax

Demo

It's simple!

class ContactsController < ApplicationController

  # load and authorize resources
  before_actions do
    # listing actions
    only(:index) { @contacts = Contact.all }

    # building actions
    only(:new)    { @contact = Contact.new }
    only(:create) { @contact = Contact.new(contact_params) }

    # member actions, will raise a 404 if the model is not found
    only(:show, :edit, :update, :destroy) { @contact = Contact.find(params[:id]) }
  end

  after_actions do
    all { your_code_here }
    except(:index) { your_code_here }
  end


  around_actions do
    only(:create) do |controller, action|
      your_code
      action.call
      in_here
    end
  end

  ...

  def contact_params
    params.require(:contact).permit(:name)
  end
end
