Question

I’d like to create a before_filter method in my application controller like this…

def check_role(role_name)   unless logged_in_user.has_role? role_name     flash[:notice] = 'Access to that area requires additional privileges.'     redirect_to :back   end end 

However, it doesn’t look as though before filters can take parameters.

Is there a way to parameterize this call, or am I trying to drive a screw with a hammer?

You should be able to do this with a block:

before_filter {|controller| controller.check_role('admin') }
