Class DS.NotFoundError

Extends: AdapterError
Defined in: addon/-private/adapters/errors.js:283
Module: ember-data

A DS.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 DS from 'ember-data';

const { NotFoundError } = DS;

export default Route.extend({
  model(params) {
    return this.get('store').findRecord('post', params.post_id);
  },

  actions: {
    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;
      }
    }
  }
});
