Deprecation Guide for Implicit Route Model

Previously, if no Route#model hook was specified and a _id parameter was present, Ember would attempt to figure out how to load that model for you. Specify your own model hook to load from the store, if desired.

An optional feature, called no-implicit-route-model, can be turned on to clear this deprecation and opt in to the new behaviour. This optional feature is enabled in blueprints as of v5.7.0 and will be removed in v6.0.0. For more information, see the optional features guides.

For example:

import { Route } from '@ember/routing/route';
import { service } from '@ember/service';

export default class MyModelRoute extends Route {
  @service store;

  model({ my_model_id }) {
    return this.store.findRecord('my-model', my_model_id);
  }
}
