EmberJS: Loading Multiple Models on a Single Route

While embarking on an EmberJS journey, developers may encounter the challenge of loading multiple unrelated models on the same route. Here's how to tackle this issue:

Consider the Route

First, assess whether the route dynamically loads data based on a slug parameter ":id". If so, refrain from loading multiple models in the model hook. Why? Because when linking to such a route with a model, Ember ignores the model hook.

Alternatives to the Model Hook

  • SetupController/afterModel: Load additional models in these hooks. If waiting is necessary, return a promise from afterModel and manually manage results within setupController.
  • Ember Data: Use store.find('resource') in the model hook. Ember Data will automatically handle async interactions.

Handling Non-Dynamic Routes

If the route does not dynamically load data based on a parameter, here are the options:

  • Multiple Models in the Model Hook: Return an object with multiple model keys and values.
  • RSVP Hash: Load promises or plain values as a hash using Ember.RSVP.hash({ modelKey: promise/value, ... }).
  • Mix and Match: Combine RSVP hashes with non-promise values, RSVP will adjust accordingly.

Additional Considerations

  • If any model needs blocking, return a promise from afterModel in addition to using other methods.
  • Setup controller can be used to further modify or associate models, e.g., setting dependencies.
  • Remember that these techniques are route-specific and do not apply to nested routes.
