Passing parameters to before_filter methods in Rails

If you have methods in your controller class that requires parameters you can still user them as filters.

Example:

def require_role(role)

#do some stuff with 'role' parameter

end

We can use it like this:

before_filter do |controller_instance|

controller_instance.require_role :admin

end

In fact, you can still use :only and :except if you need it, example:

before_filter :only => :index do |controller_instance|

controller_instance.require_role :admin

end

Have a nice day.
