name space and before filter

is it possible to have a before filter apply to all controllers in a name space, or do you have to do it separate for each individual controller. for example, an admin name space with a require_admin before filter.

easiest way is to have those controllers inherit from some common controller.

Freds tip is good, if you don't want to do it, you can test for the name space in the filter like: request.path.starts_with?('/admin')

thanks fred, that is a clean and easy solution.
