We will have a "new" resource called registrants, so we would want to make a REST API for it. There are 5 routes that will allow us to interact with this resource with admin perms, they are the following:

Get all registrants

GET: {{server_url}}/api/admin/events/{{event_id}}/registrants

Things expected from the request body:

• Nothing

Things to return:

• All registrants from event with {{event_id}}, each registrant is populated with the referenced user model in the userId field. (You should be able to just use .populate())

Get registrants by ID

GET: {{server_url}}/api/admin/events/{{event_id}}/registrants//{{user_id}}

Things expected from the request body:

• Nothing

Things to return:

• Registrants with {{user_id}} from event with {{event_id}}, the registrant is populated with the referenced user model in the userId field. (You should be able to just use .populate())

Attach registrant by ID

POST: {{server_url}}/api/admin/events/{{event_id}}/registrants//{{user_id}}

Things expected from the request body:

• [Required] userId : ObjectID
  • The user must exist within our users collection, but also must not already be a registrant for this event (Maybe make a validator ?)
• [Required] All keys in additionalFieldsSchema field of the event to attach to
  • For now, all values should be casted to string

Things to return:

• 200OK
• The newly attached registrant, populated with the user referenced

Patch event by ID

PATCH: {{server_url}}/api/admin/events/{{event_id}}/registrants//{{user_id}}
