This is really key. Even extremely common patterns that will be present in virtually every web app have no examples that I can find anywhere on the web. A great example is simple nested resources, where the URL is something like `/tv_shows/555/seasons/3/episodes/2`. Obviously, this is the page that displays info about episode 2 of season 3 of the TV show with id 555. So how do I reference the tv_show model (which I will almost certainly need to do) from the `EpisodesIndexController` or the `episodes/index` template? Do I really have to specify `needs` [0] on every controller nested under `TvShowsController`, and perhaps add a `setupController` hook to make the property easily accessible like in this tutorial [1]?

Granted, I'm pretty new to this, so maybe I'm just missing the obvious way to do this sort of thing clearly.

These are the first three results for "Ember nested routes" on Google. They're all pretty simple and straightforward. Hope that helps!

Perhaps my wording wasn't great, but I'm talking about the specific issue that I explain later in the paragraph.

Ah, my apologies! I am also learning Ember, so I am not entirely sure. Hopefully someone else can come along and enlighten both of us.

I have a large, complex Ember.js + Ember-Data + Flask API app, and I don't think that I use `needs` anywhere in the codebase, so I don't think it's absolutely necessary. IIRC, the documentation says that `needs` only applies to singleton controllers. If you have a controller associated with a model (vs. a view + controller + route combo), I would assume that it's not a singleton (i.e. controllers associated with a view are singletons in that Controller.init() is only called once, even when switching away and back to a view).

To use my example of an app with URLs like "/tv_shows/555/seasons/3/episodes/2", if you're in the episodes/index controller (or template or view), how do you reference the particular season and tv_show that episode is part of?
