Rails - Sep 2006 - Access protected flash in block of before_filter?

Hi all

I''d like to put a block after a before_filter instead of calling a 
separate method because I think it''s looking cooler. ;-)

before_filter :only => [:new, :create] do |controller|
  flash[:notice] = "That is not allowed!."
  redirect_to :referer
end

Sadly this doesn''t work:

ndefined local variable or method `flash'' for 
SchmuckSeitenController:Class

I tried it with controller.flash, but then Rails tells me it is 
protected.
Is there a way to access flash? :-)

Thanks
Josh

You can wrap your filter body in a controller.instance_eval block.

But this is really a job for verify:

Thanks, mate. I tried it the following way, but it doesn''t work:

  verify  :only => [:new, :create],
          :add_flash => {:notice => ''Creation is
deactivated.''},
          :redirect_to => :back

I want to prevent the user from creating a new object, but maybe later I 
will allow it to the user. So I just want to make sure he can''t access 
the new and create methods.
