Restrict

A rails controller extension, that gives you the possibility to restrict access to your controller actions.

Installation

gem 'restrict'

Compatibility

Works with rails 3 and 4 and all versions every ruby 2.

Usage

class GoodiesController < ApplicationController
  restrict :take
  restrict :delete, allow_if: :goodie_manager?

  def take
    # Grab a goodie
  end

  def delete
    # Remove all the goodies
  end

  private

  def goodie_manager?
    # Your domain implementation
  end
end

What that does:

1. Any anonymous access to one of both methods will raise Restrict::LoginRequired
2. If a current_user exists the access to take is allowed
3. If a current_user exists but goodie_manager? returns false, then Restrict::AccessDenied will be raised
4. If a current_user exists and goodie_manager? is true, the access is allowed

Restrict all actions

restrict :all_actions

This one will apply to all actions on this controller. It takes the allow_if option as well.

Configuration

# Default is :user_signed_in?
Restrict.config.authentication_validation_method = :current_user

You may set the method that is used to figure out whether a user is signed in or not to whatever you like, however it's default is :user_signed_in? which is the most common (devise) method in use.

Todo Ideas

• restrict :all_actions, except: [:new], allow_if: 'dsfsdf'
