This hook is provided the current `transition` attempt as a parameter, which can be used to `.abort()` the transition, save it for a later `.retry()`, or retrieve values set on it from a previous hook. You can also just call `router.transitionTo` to another route to implicitly abort the `transition`. You can return a promise from this hook to pause the transition until the promise resolves (or rejects). This could be useful, for instance, for retrieving async code from the server that is required to enter a route. @method beforeModel @param {Transition} transition @return {any | Promise<any>} if the value returned from this hook is a promise, the transition will pause until the transition resolves.

Calling `this.router.transitionTo` from inside of the `redirect` hook will abort the current transition (into the route that has implemented `redirect`). `redirect` and `afterModel` behave very similarly and are called almost at the same time, but they have an important distinction when calling `this.router.transitionTo` to a child route of the current route. From `afterModel`, this new transition invalidates the current transition, causing `beforeModel`, `model`, and `afterModel` hooks to be called again. But the same transition started from `redirect` does _not_ invalidate the current transition. In other words, by the time the `redirect` hook has been called, both the resolved model and the attempted entry into this route are considered fully validated. @method redirect @param {Object} model the model for this route @param {Transition} transition the transition object associated with the current transition @since 1.0.0 @public */ redirect(_model, _transition) {} /** Called when the context is changed by router.js. @private @method contextDidChange */ contextDidChange() { this.currentModel = this.context; } /** A hook you can implement to convert the URL into the model for this route. ```app/router.js // ... Router.map(function() { this.route('post', { path: '/posts/:post_id' }); }); export default Router; ``` Note that for routes with dynamic segments, this hook is not always executed. If the route is entered through a transition (e.g. when using the `link-to` Handlebars helper or the `transitionTo` method of routes), and a model context is already provided this hook is not called. A model context does not include a primitive string or number, which does cause the model hook to be called. Routes without dynamic segments will always execute the model hook. ```javascript // no dynamic segment, model hook always called this.router.transitionTo('posts'); // model passed in, so model hook not called thePost = store.findRecord('post', 1); this.router.transitionTo('post', thePost); // integer passed in, model hook is called this.router.transitionTo('post', 1); // model id passed in, model hook is called // useful for forcing the hook to execute thePost = store.findRecord('post', 1); this.router.transitionTo('post', thePost.id); ``` This hook follows the asynchronous/promise semantics described in the documentation for `beforeModel`. In particular, if a promise returned from `model` fails, the error will be handled by the `error` hook on `Route`. Note that the legacy behavior of automatically defining a model hook when a dynamic segment ending in `_id` is present is [deprecated](https://deprecations.emberjs.com/v5.x#toc_deprecate-implicit-route-model). You should explicitly define a model hook whenever any segments are present. Example ```app/routes/post.js import Route from '@ember/routing/route'; import { service } from '@ember/service'; export default class PostRoute extends Route { @service store; model(params) { return this.store.findRecord('post', params.post_id); } } ``` @method model @param {Object} params the parameters extracted from the URL @param {Transition} transition @return {any | Promise<any>} the model for this route.

This method is called with the controller for the current route and the model supplied by the `model` hook. By default, the `setupController` hook sets the `model` property of the controller to the specified `model` when it is not `undefined`. If you implement the `setupController` hook in your Route, it will prevent this default behavior. If you want to preserve that behavior when implementing your `setupController` function, make sure to call `super`: ```app/routes/photos.js import Route from '@ember/routing/route'; import { service } from '@ember/service'; export default class PhotosRoute extends Route { @service store; model() { return this.store.findAll('photo'); } setupController(controller, model) { super.setupController(controller, model); this.controllerFor('application').set('showingPhotos', true); } } ``` The provided controller will be one resolved based on the name of this route.

Router.map(function() { this.route('post', { path: '/posts/:post_id' }); }); export default Router; ``` If you have defined a file for the post controller, the framework will use it.

During a transition, all routes must resolve a model object, and if a route needs access to a parent route's model in order to resolve a model (or just reuse the model from a parent), it can call `this.modelFor(theNameOfParentRoute)` to retrieve it. If the ancestor route's model was a promise, its resolved result is returned. Example ```app/router.js // ... Router.map(function() { this.route('post', { path: '/posts/:post_id' }, function() { this.route('comments'); }); }); export default Router; ``` ```app/routes/post/comments.js import Route from '@ember/routing/route'; export default class PostCommentsRoute extends Route { model() { let post = this.modelFor('post'); return post.comments; } } ``` @method modelFor @param {String} name the name of the route @return {Object} the model object @since 1.0.0 @public */ modelFor(_name) { let name; let owner = getOwner(this); (isDevelopingApp() && !(owner instanceof EngineInstance) && assert('Expected router owner to be an EngineInstance', owner instanceof EngineInstance)); let transition = this._router && this._router._routerMicrolib ? this._router._routerMicrolib.activeTransition : undefined; // Only change the route name when there is an active transition. // Otherwise, use the passed in route name. if (owner.routable && transition !== undefined) { name = getEngineRouteName(owner, _name); } else { name = _name; } let route = owner.lookup(`route:${name}`); // If we are mid-transition, we want to try and look up // resolved parent contexts on the current transitionEvent. if (transition !== undefined && transition !== null) { let modelLookupName = route && route.routeName || name; if (Object.prototype.hasOwnProperty.call(transition.resolvedModels, modelLookupName)) { return transition.resolvedModels[modelLookupName]; } } return route?.currentModel; } [RENDER_STATE] = undefined; /** `this[RENDER]` is used to set up the rendering option for the outlet state. @method this[RENDER] @private */ [RENDER]() { this[RENDER_STATE] = buildRenderState(this); once(this._router, '_setOutlets'); } willDestroy() { this.teardownViews(); } /** @private @method teardownViews */ teardownViews() { if (this[RENDER_STATE]) { this[RENDER_STATE] = undefined; once(this._router, '_setOutlets'); } } /** Allows you to produce custom metadata for the route.
