Adding Panel to Add Event Types in Admin Dashboard of Open Event Frontend

This blog will illustrate how to add a new section to admin dashboard of Open Event Frontend which allows admin to add event types. For this we need modals to display a form by which we can edit or add a new event type and we need to create a new route admin/content/events. To create a new route we use ember CLI command:

ember g route admin/content/events

The primary end point of Open Event API with which we are concerned with for creating a new event type or topic is:

GET/POST/DELETE        /v1/event-types

The model concerned with event types is:

 name : attr('string'),
 slug : attr('string'),

 events: hasMany('event')


This model is very basic and contains only name and slug and a relationship to event model. Next we want to fetch the existing event types and display them in table. We write queries which fetches data in event-type model in the route file admin/content/events.js.

import Route from '@ember/routing/route';
export default Route.extend({
 titleToken() {
   return this.get('l10n').t('Social Links');
 async model() {
   return {
     'eventTopics': await this.get('store').query('event-topic', {}),
     'eventTypes': await this.get('store').query('event-type', {})


This will fetch the data in our model. Next we need to display this data in a template for which we define a table that will display each event type.

<button class="ui blue button {{if device.isMobile 'fluid'}}" {{action 'openNewEventTypeModal'}}>{{t 'Add New Event Type'}}</button> 

      <table class="ui celled table">
           {{#each model.eventTypes as |eventType|}}


We have two buttons that are used to edit or delete a event type. Both buttons open up a modal to achieve this functionality. We also have a “Add new Event Type” button at the top. This buttons opens up a modal and sends out a action to its controller when user successfully fills up the name of the event type. Let us take a look at the code of our controller that saves/deletes our event type to server.

addEventType() {
     this.set('isLoading', true);
       .then(() => {
        // Success message
       .catch(()=> {
        //failure message
       .finally(() => {
         this.set('isLoading', false);


deleteEventType(eventType) {
     this.set('isLoading', true);
       .then(() => {
        // Success
       .catch(()=> {
       .finally(() => {
         this.set('isLoading', false);


In addNewEventType() function we take the data from the form and save the model, which eventually sends POST request to save the new Event Type on server. This returns a JavaScript promise and we handle it via then and catch. It goes to then block if promise resolves and goes to catch is promise rejects/fails.

Similarly in delete function we take the eventType which is passed as model of event-type object and call destroyRecord() function which eventually sends out a DELETE request to server and data gets deleted. Here also we handle the response via resolve and reject depicted with then and catch respectively.
