Accessing JSON data model from Ember route or controller

Exploring the capabilities of Ember.js

Is it possible to expose my data model as JSON through a route or controller?

The object saved in the store looks like this:

this.store.createRecord('Person', {
  id: 1,
  name: this.get('name'),
  email: this.get('email')
});

I aim to present this data as a JSON object from either a route or controller without involving any views.

Can this be achieved? Thank you for your assistance!

EDIT The route is defined as follows:

App.ResultRoute = Ember.Route.extend({
model: function() { 
   return this.store.find('person', 1);
   }
});

The '1' specifies that only this record should be fetched. This approach displays the {{name}} and {{email}} in the view corresponding to the Person object. However, I want to obtain just the JSON representation. I attempted the following suggested solution:

App.ResultRoute = Ember.Route.extend({
  afterModel: function (model) {
  model.get('content').forEach(function (item) {
    console.log(item.get('content'));
   });
 } 
});

But an error occurred:

Uncaught Error: Assertion Failed: Error: More context objects were passed than there are dynamic segments for the route: error

What could be causing this error?

Answer №1

To streamline this process, I would implement an API within my model that delivers a straightforward JSON object to any requester. Within the Person model, there would be a method called getPersonDetails that conceals all internal complexities, such as attributes and associations, and simply presents the state of the specific person object it is being called upon. For instance, if one needed to showcase a table of persons or similar data set, they could create a record and easily retrieve the details from the newly created person object.

Answer №2

To get started, refer to this guide from the beginning: . It will walk you through how to specify a model for a route.

Next, it's important to thoroughly read this guide on controllers: .

Generally, to access data from the route's model hook, you can use:

this.store.find('person') // All records

If you want to retrieve the first object as JSON, you can do:

var person_JSON = this.store.find('person').then(function (persons) {
  console.log(persons.objectAt(0).get('content'));
});

You can also loop through all records and extract the content to generate raw JSON without Ember wrapping depending on your requirements.

The ideal place to implement this would be in the route's afterModel hook. In this case, you wouldn't need to handle promises as Ember takes care of it for you:

afterModel: function (model) {
  model.get('content').forEach(function (item) {
    console.log(item.get('content'));
  });
}

Hope this information is useful.

Edit: For one record, try this:

afterModel: function (model) {
  console.log(model.get('content'));
}
