Class NotFoundError

public

Defined in: ../adapter/addon/error.js:281

A NotFoundError equates to a HTTP 404 Not Found response status. It is used by an adapter to signal that a request to the external API was rejected because the resource could not be found on the API.

An example use case would be to detect if the user has entered a route for a specific model that does not exist. For example:

app/routes/post.js

import Route from '@ember/routing/route';
import { NotFoundError } from '@ember-data/adapter/error';
import { inject as service } from '@ember/service';
import { action } from '@ember/object';

export default class PostRoute extends Route {
  @service store;
  model(params) {
    return this.get('store').findRecord('post', params.post_id);
  }
  @action
  error(error, transition) {
    if (error instanceof NotFoundError) {
      // redirect to a list of all posts instead
      this.transitionTo('posts');
    } else {
      // otherwise let the error bubble
      return true;
    }
  }
}
