Rails 3 - overwriting routes

I'm currently having some problems with setting up the right routes for my application.

In short I would like to have URLs like so:

explanation:

Show actual page for the selected poll

abstract:

localhost:3000/polls/:category_slug/:poll_id

example:

localhost:3000/polls/technology/1337

routes.rb

get 'polls/:category_slug/:poll_id' => 'polls#show', :as => :poll

Furthermore the user should be able to filter the polls against some criteria, like show Top-Polls, New-Polls and so on...

explanation:

Show a list of polls, which are matching the selected criteria

abstract:

localhost:3000/polls/:category_slug/:filter_mode

example:

localhost:3000/polls/technology/top

routes.rb

get 'polls/:category_slug/:filter_mode' => 'filter#by_mode', :as => :polls_filter

And here's the problem

ActiveRecord::RecordNotFound : Couldn't find Poll with ID=top_all

The second route ('polls/:category_slug/:filter_mode') is overwriting the first route so Rails recognizes the :filter_mode as a :poll_id.

So my question is, how can I change this behavior, so both routes will actually work

without overwriting each other ? (the first route will work perefectly, when I leave out the second one)

I hope someone under开发者_Go百科stands my problem, appreciate every help.

You can set a constraint on the filter one to take only strings, and then put it before the other one. It will fall through to the poll_id one.
