return from an action

Hello,

I would like to exit an action, however, I cannot use return because it should be called from another method:

def click     requires_valid_login     other_things end

protected def requires_valid_login     if !@user        flash[:error] = 'you must be logged for view this page'        redirect_to :back     end end

Is there any elegant way to exit from action :click and don't process "other things"?

I could use:     requires_valid_login or return

However I don't like this.

Hope this helps...

def click   return unless valid_login   other_things end

def valid_login      if !@user         flash[:error] = 'you must be logged for view this page'         redirect_to :back         false      end      true end

Uhhhh to keep the syntax ruby-like you should rename valid_login to valid_login?

Use a before_filter and return false, aborting the action.

Thank you, I am already using before filter which does the authentication, however I don't want to abort every actions, only some of them.

Is it possible to abort the action inside from a method called by the action itself?

That's what I am trying to avoid, the explicit return from the action itself.
