Rails - May 2006 - Can you have multiple before filters?

Hi,

Is it possible to specify multiple before filters in a controller... 
here''s the thing: only one set of filters is to use the :except option.
Something like:

before_filter :check_for_session_cookie
before_filter :validate_user :except =>[''login'']

which I use to a) check if the user has returned to the site and has a 
saved cookie holding login details b) check to see if user is logged on, 
unless they are attempting to do so.

As far as I can tell the :except is applied to both my before filters. 
Am I right in thinking this is because both my filters are chained, and 
the :except is applied to the chain?

thanks
Lindsay

I am using two filters without any problems like so:

  before_filter :auth_login
  before_filter :get_group, :only => [:edit, :delete, :show]

the :auth_login is always performed.  I also checked this with an
:except option on my :get_group before_filter and the auth_login still
worked.

So, I suspect the problem lies somewhere else.  Your filters should be
able to specify different conditions.

Feel free to post more info if you need more help.

Good Luck,
Tom

Is this an email typo, or is this your actual code?

Hi Pat, yes its an email typo. Sorry about that! I''ve followed up on 
what Tom has said. There is a problem with my code elsewhere in the app 
-  I''ll figure that out. The before_filters are working properly, which
is good to know.

thanks
Lindsay
