[Rails] Anything like with_scope for ActionController?
There are areas of my application that "want" to use a url structure like domain/<human_readable_param>/<Module>/<Controller>/<Action>/<Id> Please note that the human readable parameter I need to inject is NOT related to the <id> being used by the action/controller pair. It''s identifying a container object whose contains are operated on by the actions. I currently have this working with routes, however I need to tack on an extra parameter to all the url generating functions (url_for, form_start_tag, named_route_url...) to get the mapping to pick up the custom URL parameter. Having to remember to append :short_name=>@my_object.short_name (with or without to_param magic), is getting annoying and the repetition is getting ugly. Is there anything like ActiveRecord''s with_scope function to "bind" this extra parameter once and make ActionController smart about propagating the extra parameter everywhere? Thank you. Eric
Just put it the shared logic in application_controller.rb.

Sorry, I meant to say in application.rb and use a before filter to
call for each necessary method.

Yeah, I wasn''t suggesting any fancy Ruby magic of opening up Rails
classes and adding an optional parameter.
I was just saying that you could create a bunch of your own methods
like my_url_for and my_form_tag that would call the real functions
with your parameter added. You would put your methods in
application.rb. It''s not as DRY as opening up one class and getting
the functionality for all methods, but it''s still DRY.
If you use my naming scheme and "miss a function" you''ll get
an
immediate application error.
