Hi, I seem to be getting a routing error due to a before filter I have puut in application.rb that assists with localization. The before\_filter is checking the locale and in this case is performing a redirect. The parameters look ok just as the redirect request is set off in the before\_filter, BUT THEN the URL that comes back from the client is WRONG with double entries (e.g. “/active\_rbac/active\_rbac/login/login”) Any advice on how to fault find this? Could this be the way rails determines what the URL should be for a request. Does it back-calculate from routes.rb information? Perhaps I’ve got inconsistent data in my routes.rb file (e.g. more than one map with same number of parameters). I’ll copy my routes.rb below.

PS. ummm…can ones routes.rb can contain more than one mapping with the same number of parameters or not? i.e. if it did how would rails know how to back calculate a url\_for or a redirect\_to request? Wonder if this would explain my problem? I have the following lines in my routes.rb that both have 4 parameters: … map.connect ‘:controller/:action/:sort/:order’ map.connect ‘:locale/:controller/:action/:permalink’ … ---

Can anyone provide an overview of the business logic behind the “url\_for” functionality in relation to how it works given there may be many routes specified in ones “routes.rb” file? How does it determine which mapping to use & rules behind populating the URL? I stated to look at the rails code around started getting a headache ☹ (still not quite up to this level in ruby/rails)
