How to force a DictField to be documented as an object, not a string?

[tardate]

When passing a dict/hash of arbitrary data in an API, we're using DictField (same applies for JSONField). A good example is an errors collection, where we really don't want to define a serializer with all the possible elements it may contain. So we declare like this:

class CustomSerializer(serializers.Serializer):
    errors = serializers.DictField(
        required=False, help_text="Error conditions, if any"
    )

The problem is this shows up in the swagger UI as a string:

CustomSerializer {
  errors (string): Error conditions, if any
}

Likewise in swagger doc:

"CustomSerializer": {
  "required": [
    "errors"
  ],
  "id": "CustomSerializer",
  "properties": {
    "errors": {
      "description": "Error conditions, if any",
      "required": false,
      "readOnly": false,
      "type": "string"
    }
  }
},

This is causing problems for API clients that are attempting to introspect on the basis of the swagger doc. Is there a way to define these elements better - at least not have them declared as a string? Am I missing something obvious?

Note we are still on 0.3.x branch (0.3.10)

Unfortunately this is not supported in the 0.3.x., but is now possible in the latest version
