I'm using the above REST API (GET /rest/api/3/field) to get all fields with their types.
When I examine the resulting JSON, each custom fields has the dict entry some_entry['schema']['type'],
the value being the field type.
There are two problems:
1. Both radio buttons and checkbox return the same value, ':radiobuttons'
2. All selections (single, multi and cascade) return the same value, ':select'
Any idea how to make this distinction?
