Implementing JSON API for ‘settings/contact-info’ route in Open Event Frontend

In Open Event Frontend, under the settings route, there is a ‘contact-info’ route which allows the user to change his info (email and contact). Previously to achieve this we were using the mock response from the server. But since we have the JSON API now we could integrate and use the JSON API for it so as to let the user modify his/her email and contact info. In the following section, I will explain how it is built:

The first thing to do is to create the model for the user so as to have a skeleton of the database and include our required fields in it. The user model looks like:

export default ModelBase.extend({
  email        : attr('string'),
  password     : attr('string'),
  isVerified   : attr('boolean', { readOnly: true }),
  isSuperAdmin : attr('boolean', { readOnly: true }),
  isAdmin      : attr('boolean', { readOnly: true }),

  firstName : attr('string'),
  lastName  : attr('string'),
  details   : attr('string'),
  contact   : attr('string'),

Above is the user’s model, however just the related fields are included here(there are more fields in user’s model). The above code shows that email and contact are two attributes which will accept ‘string’ values as inputs. We have a contact-info form located at ‘settings/contact-info’ route. It has two input fields as follows:

<form class="ui form {{if isLoading 'loading'}}" {{action 'submit' on='submit'}} novalidate>
  <div class="field">
    <label>{{t 'Email'}}</label>
    {{input type='email' name='email'}}
  <div class="field">
    <label>{{t 'Phone'}}</label>
    {{input type='text' name='phone'}}
  <button class="ui teal button" type="submit">{{t 'Save'}}</button>

The form has a submit button which triggers the submit action. We redirect the submit action from the component to the controller so as to maintain ‘Data down, actions up’. The code is irrelevant, hence not shown here. Following is the action which is used to update the user which we are handling in the contact-info.js controller.

updateContactInfo() {
      this.set('isLoading', true);
      let currentUser = this.get('model');{
        adapterOptions: {
          updateMode: 'contact-info'
        .then(user => {
          this.set('isLoading', false);
          let userData = user.serialize(false).data.attributes;
 = user.get('id');
          this.get('authManager').set('currentUserModel', user);
          this.get('session').set('data.currentUserFallback', userData);
          this.get('notify', 'Updated information successfully');
        .catch(() => {

We are returning the current user’s model from the route’s model method and storing it into ‘currentUser’ variable. Since we have data binding ember inputs in our contact-info form, the values will be grabbed automatically once the form submits. Thus, we can call ‘save’ method on the ‘currentUser’ model and pass an object called ‘adapterOptions’ which has key ‘updateMode’. We send this key to the ‘user’ serializer so that it picks only the attributes to be updated and omits the other ones. We have customized our user serializer as:

if (snapshot.adapterOptions && snapshot.adapterOptions.updateMode === 'contact-info') { = pick(, ['email', 'contact']);

The ‘save’ method on the ‘currentUser’ ‘’ returns a promise. We resolve the promise by setting the ‘currentUserModel’ as the updated ‘user’ as returned by the promise. Thus, we are able to update the email and contact-info using the JSON API.
