named routes does not handle parameters with a "." in the values

Reported by Jean-Marc Lagacé | September 17th, 2008 @ 07:44 PM | in 2.x


I have the following problem with the routes... I first thought it was a mis-configuration from my part but I can reproduce it at will on a blank new application.

Let's say you have a resource called Dummy (with the routes and controller). From the console the following will fail with Rails 2.0.2, 2.1.0 and 2.1.1:


All of those generates the same message:

ActionController::RoutingError: dummy_url failed to generate from {:controller=>"dummies", :action=>"show", :id=>"a-sd.ef"}, expected: {:controller=>"dummies", :action=>"show"}, diff: {:id=>"a-sd.ef"}

    • Title changed from “named routes does not handle parameters with a "." in the values” to “why it is important (well at least to me)”

    My urls contains the user name of the users on the site. I am allowing the "." as part of the name...

    I can disable that feature but it's a bit silly a simple "." would crash it

    • Assigned user set to “Michael Koziarski”
    • State changed from “new” to “incomplete”

    Could you submit a failing test case please ?

    Hi Micheal,

    While putting a failing test case in place I found a way to make it work without changing any of the ActionPack code. A few reasons motivated trying to find an alternative... the main one is that the decimal point allows the Route to determine if there is a format present in the URL when parsing it.

    Using the :requirements parameter of the route configuration I was finally able to put an email address as part of a named route.

    So... should I document it through a test... how should we proceed?

    • State changed from “incomplete” to “wontfix”

    The idea here is if you want dots in your ids and you're not using formats it's probably best to do something like this:

    map.resources :dummies, :requirements => {:id => /[a-zA-Z0-9\.\-_]+/ }

    I think you don't understood: this works for resources but not for named routes. I have this issue on Rails 2.3.5
