main_app routes.rb

mount MyEngine::Engine => '/', :as => 'my_engine'

my_engine's routes.rb

get 'my_url' => 'MyEngine::Pages#show', :as => :my_url

in views:


results in "http://localhost:3000//my_url" (note the incorrect '//')

Is there a reason why you use the suffix "_url" in your route name? BTW I attempted to duplicate this without much luck.

the _url is just a naming, not actual generator (as for example _path or _url). i should have chosen better name.
perhaps i also forgot to say, that the engine is not isolated.
i will try to look for some example on which to show this issue …

I think you should mount your engine as

mount MyEngine::Engine => '', :as => 'my_engine'

yes, that would make sense, right? unfortunately:

Right, 1.8 doesn't allows empty strings to be transormed to symbols. If you tried the same in 1.9, it'd work.
