protect_from_forgery

v2.3.8 - Show latest stable - 1 note - Class: ActionController::RequestForgeryProtection::ClassMethods

protect_from_forgery(options = {}) public

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
  end

Valid Options:

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

        if options[:secret] || options[:digest]
          ActiveSupport::Deprecation.warn("protect_from_forgery only takes :only and :except options now. :digest and :secret have no effect", caller)
        end

form_authenticity_token

Instead of disabling the CSRF check you can pass the authenticity_token field in your forms, eg:

<%= hidden_field_tag :authenticity_token, form_authenticity_token -%>
