Rails 3 Routing Constraint and Regex

Question

I\'m looking to match the pattern state/city in the path, unless the state variable equals \"auth\"

match \'/:state/:city\' => \'cities#index         


        

Answer 1

You should be able to define your /auth route before your state/city routes:

Route priority

Not all routes are created equally. Routes have priority defined by the order of appearance of the routes in the config/routes.rb file. The priority goes from top to bottom.

So this order should do the right thing:

match '/auth/twitter' => ...
match '/:state/:city' => ... 

You might want to avoid the problem altogether by putting your state/city routes into their own namespace:

match '/place/:state/:city' => ...

That leaves the top level clear for other future uses.
