Hi Everyone, I want to redirect the user to login page, when he is trying to use access unavailable page. Usually it throws me a exception error and 404 page. But here when user got 404 error he will be redirected to login page, I modified the method perform\_action under the file /vendor/rails/actionpack/lib/action\_controller/base.rb as follows:       def perform\_action         if self.class.action\_methods.include?(action\_name)           send(action\_name)           default\_render unless performed?         elsif respond\_to? :method\_missing           method\_missing action\_name           default\_render unless performed?         elsif template\_exists? && template\_public?           default\_render         else      #the coding was changed for to avoid 404 errors on 06/04/08      #flash[:notice]="Seems that the page you were looking for does not exist, so you\'ve been redirected here."      redirect\_to :controller=\>'account', :action=\>'login'           #raise UnknownAction, "No action responded to #{action\_name}", caller         end       end Its working well shall I override this function in my application controller or in some where my app files cos its now in vendor folder, regards, veeraa ---

Why do that? That's silly! You should simply catch an exception and redirect to another page rather than do that... but better to use a before\_filter. Julian. Learn Ruby on Rails!
