The Open Event Server enables organizers to manage events from concerts to conferences and meetups. 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 different events role concerning a user on Open Event Server. The focus is on its model and Schema updation.
For the User Table, we’ll update our User Model as follows:
Now, let’s try to understand these hybrid properties.
In this feature, we are providing Admin the rights to see whether a user is acting as a organizer, co-organizer, track_organizer, moderator, attendee and registrar of any of the event or not. Here, _is_role method is used to check whether an user plays a event role like organizer, co-organizer, track_organizer, moderator, attendee and registrar or not. This is done by querying the record from UserEventsRole model. If the record is present then the returned value is True otherwise False.
For the User Model, we’ll update our Schema as follows
Now, let’s try to understand this Schema.
Since all the properties will return either True or false so these all properties are set to Boolean in Schema. Here dump_only means, we will return this property in the Schema.
So, we saw how User Model and Schema is updated to show events role concerning a user on Open Event Server.
