Answer 1

With Rails 4, you now have the option to write in skip_before_action instead of skip_before_filter.

# Works in Rails 4 and 5
skip_before_action :verify_authenticity_token

or

# Works in Rails 3 and 4 (deprecated in Rails 4 and removed in Rails 5)
skip_before_filter :verify_authenticity_token

Answer 2

In Rails3 you can disable the csrf token in your controller for particular methods:

protect_from_forgery :except => :create 

Answer 3

In the controller where you want to disable CSRF the check:

skip_before_action :verify_authenticity_token

Or to disable it for everything except a few methods:

skip_before_action :verify_authenticity_token, :except => [:update, :create]

Or to disable only specified methods:

skip_before_action :verify_authenticity_token, :only => [:custom_auth, :update]
