Route helper for resource is not created

I have the following resource:

``` js
this.resources('users', { only: ['index', 'edit', 'update', 'destroy'] });
```

So, I don't have page to view user information (`users#show`), but I do have page to edit it (`users#edit`) and action to update if (`users#update`).
The problem is that in this case the route helper `userPath` is not generated and I can't set `action` attribute of the user's edit form:

``` html
...
```

Start by tracing the resources(...) route-generation entry point for the listed index, edit, update, and destroy actions. Check how the edit form's userPath(user) expression is resolved, and consider the work complete when that helper is available for this resource configuration and produces the form action shown.
