Adding Modules API on Open Event Server

Adding Modules API on Open Event Server

The Open Event Server enables organizers to manage events from concerts to conferences and meet-ups. It offers features for events with several tracks and venues. Event managers can create invitation forms for speakers and build schedules in a drag and drop interface. The event information is stored in a database. The system provides API endpoints to fetch the data, and to modify and update it.

The Open Event Server is based on JSON 1.0 Specification and hence build on top of Flask Rest Json API (for building Rest APIs) and Marshmallow (for Schema).

In this blog, we will talk about how to add API for accessing the Modules on Open Event Server. The focus is on Schema creation and it’s API creation.

Schema Creation

For the ModuleSchema, we’ll make our Schema as follows

Now, let’s try to understand this Schema.

In this feature, we are providing Admin the rights to set whether Admin wants to include tickets, payment and donation in the open event application.

  1. First of all, we will provide three fields in this Schema, which are ticket_include, payment_include and donation_include.
  2. The very first attribute ticket_include should be Boolean as we want Admin to update it whether he wants to include ticketing system in the application from default one which is False.
  3. Next attribute payment_include should be Boolean as we want Admin to update it whether he wants to include payment system in the application from default one which is False.
  4. Next attribute donation_include should be Boolean as we want Admin to update it whether he wants to include donation system in the application from default one which is False.

API Creation

For the ModuleDetail, we’ll make our API as follows

Now, let’s try to understand this API.

In this API, we are providing Admin the rights to set whether Admin wants to include tickets, payment and donation in the open event application.

  1. First of all, there is the need to know that this API has two method GET and PATCH.
  2. Decorators shows us that only Admin has permissions to access PATCH method for this API i.e. only Admins can modify the modules .
  3. before_get method shows us that this API will give first record of Modules model irrespective of the id requested by user.
  4. Schema used here is default one of Modules
  5. Hence, GET Request is accessible to all the users.

So, we saw how Module Schema and API is created to allow users to get it’s values and Admin users to modify it’s values.
