# module ActionController::RequestForgeryProtection::ClassMethods

### Public Instance Methods

protect_from_forgery(options = {}) click to toggle source

Turn on request forgery protection. Bear in mind that only non-GET, HTML/JavaScript requests are checked.

Example:

    class FooController < ApplicationController
      protect_from_forgery :except => :index

You can disable csrf protection on controller-by-controller basis:

    skip_before_filter :verify_authenticity_token

It can also be disabled for specific controller actions:

    skip_before_filter :verify_authenticity_token, :except => [:create]

Valid Options:

- `:only/:except` - Passed to the `before_filter` call. Set which actions are verified.
