Hello again,

It’s possible to use before\_filter in the application\_controller, and  
exclude for some methods from other controllers ?

i have a before\_filter in application\_controller that checks if the user  
is logged, if the time hasn’t expired, … and I want to exclude some  
methods of this check, like the login. This ‘login’ belongs to other  
controller.

I can put those before\_filter in every control that will need it, but  
all of my controls need it, so I prefer to put it in the  
application\_controller.

thanks,

raimon

ps. this doesn’t work

before\_filter (:session\_expiry =\> :except ) {|login\_controller|}

Add this to your login\_controller:

skip\_before\_filter :session\_expiry
