Steps to Reproduce

• Create a data source with data files in it.
• do a REST API call on export-templates with this payload:

{
  "name": "billing",
  "slug": "billing",
  "data_source": 1,
  "data_file": 3,
  "auto_sync_enabled": true,
  "object_types": [
    "dcim.device"
  ],
  "mime_type": "application/json",
  "file_name": "billing",
  "file_extension": "json",
  "as_attachment": true,
  "template_code": "{# #}"
}

Expected Behavior

I expected an export template to be created with the data source, data file configured, that syncs the template_code from the file.

Observed Behavior

An export template was created with the 'dummy' template code. The data source is configured, but the data file is not, and the auto_sync_enabled flag is not turned on.

Suspected Cause

When checking the OPTIONS call to the export-templates endpoint, it seems that the data_file is a read_only field:

... "data_file":{"type":"nested object","required":false,"read_only":true,"label":"Data file", ...
