Demo Application

See a functional demo application for a ticket management system using Eventbrite APIs.

We'll cover the following

In this lesson, we will see a sample Django application of a ticket management system. There are two categories of users: organizer and user. We have used the following endpoints in the application:

  1. View events.
  2. Create an event.
  3. Create a ticket.
  4. Publish an event.
  5. Buy tickets using the checkout widget of Eventbrite.

Workflow and APIs

Let’s dive into the code and see how we’ve integrated different Eventbrite APIs into our web application.

User function

Let’s discuss the function of the user in the views.py file:

  • Lines 14–22: The index function retrieves live events using the organization ID and returns the events to the user’s GUI.

Click the link below the “Run” button to open the user’s page.

Organizer functions

Let’s discuss the functions of the organizer in the views.py file:

  • Lines 24–31: The dashboard function retrieves all events using the organization ID and returns the events to the organizer’s GUI.
  • Lines 33–71: The create_event function receives necessary inputs from the GUI and creates the event.
  • Lines 73–105: The create_ticket function receives necessary inputs from the GUI to create a ticket for the event. We have to create at least one ticket to publish an event.
  • Lines 107–123: The publish_event function shows the events with draft status. When we click the “Publish Event,” the event_id is used to change its status to publish as the user can only see the published events.

To open the organizer’s page, use the link given below:

Demo

Click the “Run” button to run the demo application in the widget below. Before that, don’t forget to enter the PRIVATE_TOKEN and ORGANIZATION_ID to start the server.

Note: The following widget only shows the necessary files required to explain the endpoints of Eventbrite API.
