I'm assuming that you're using some kind of Handlebars pre-compiler which is getting the template name from the path. (I've never used rails, so I don't know if that's built into Ember-rails.) If that's the case, I think you have two options.
You could attempt to modify/configure the pre-compiler so that it takes the template name from somewhere other than the path. I don't know which one you're using, so I can't really give you details.
You can change the template that the route renders. You could use the render method of
Route
, or you could defined the view for the route and change thelayoutName
property.
Personally, I would highly suggest taking advantage of nested routes, as they offer many other benefits besides template organization. But if you really don't want to, look up documentation on your pre-compiler and try option number 1. You might be able to come up with something clever.
EDIT: With Ember-Rails, option 1 is probably the best. I don't know anything about Ruby, but I'm pretty sure everything you need is in template.rb.
