Ditch the component. Whatever you’re wanting to display with “myaction”,  
work  
it in to the view with partials or as the view itself.

A cleaner way of doing this is by using a before filter in  
“mycontroller”.  
Create an action that will check for the presence of session, and call  
it as  
a before filter.

We’ll call this action “check\_for\_session”. In your controller, at the  
top,  
put this:

before\_filter :check\_for\_session

Then, define the “check\_for\_session” action in your controller and stick  
your  
session-checking logic in there. Simply use redirect\_to on failures,  
which  
will send users without sessions to the login page.

Problem solved. When “myaction” is called, the controller will run  
check\_for\_session first. If check\_for\_session doesn’t see any session,  
it  
will redirect to the login page. Nice and clean.
