Question

In Rails what is the before_filter syntax when you want to “except” controller “abc”.

Example, in the application_controller if I want to say:

before_filter :login_required :except => ["-name of controller-"]

Background – Just wanted basic authentication across the whole app except the controller that actually handles getting a user authenticated….

Answer 1

You can put the following line in the controller where the before_filter should not be executed:

skip_before_filter :login_required

You can even specifiy the methods where the before_filter is ignored with :only and :except options:

skip_before_filter :login_required, :only => [:login]

An example here.

Edit: with Rails 4, before_filter is aliased with before_action, and skip_before_filter is also aliased with skip_before_action
