Before_filter :except => [:controller => :main_menu] ? do we have such thing

Rails
1

Hi all

I have added a before_filter method in my application. Mainly most of
the controllers use that method except one controller. The whole
controller does not use this method, so I want to exclude it from the
list

I tried
before_filter :authenticate, :except => [:methods_here ]

but how can we make an except for a controller

Thanks

You can add guards in the filter, based on the controller and/or
action
names.
Example:

#in application.rb
before_filter :login_required, :except => [:welcome,:login]

 def login_required
     return if self.controller_name == 'test'  <<----- GUARD

     unless current_user
         redirect_to login_invite_url
     end
 end

Hi

Thanks for the fast answer
in fact I find a way
there is a method called
skip_before_filter
which you add it into the controller and it will do the job

Thanks

Yeah I’m using the skip_before_filter method too,
but still, it seems it would be better if you could specify a
controller/action like your original posts suggests

before_filter :custom_filter, :except => {:controler=>:action}

that way you can include the filter on everything by applying it to the
ApplicationController, and only remove it from the few
controllers/actions that don’t need it.

before_filter :filter_method, :only => :action

or

before_filter :filter_method, :except => :action

See the ‘Filter conditions’ section of

Hope that helps,
