Post dictionary value along with a file

[MacLotsen]

When sending a multipart request as follows:

-----------------------------1996172951399624151317139513
Content-Disposition: form-data; name="attrs"
Content-Type: application/json

{"test":"hello world"}
-----------------------------1996172951399624151317139513
Content-Disposition: form-data; name="files"; filename="myfile.pdf"
Content-Type: application/pdf

<pdf data>

With the following as resource:

'things': {
  'schema': {
    'files': {
      'type': 'list',
      'schema': {'type': 'media'}
    },
    'attrs': {'type': 'dict'}
  }
}

Eve will not detect that the attached json is ment te be of type 'dict'. The exact message:

{_status=ERR, _issues={env=must be of dict type}, _error={code=422.0, message=Insertion failure: 1 document(s) contain(s) error(s)}}

I have seen that it works for string types, yet dictionaries won't work. Is there any workaround present?

Also someone else encountered the problem (see link).

Got a workaround!
Override the dict validator:

class JsonValidator(Validator):

    def _validate_type_dict(self, field, value):
        if type(value) is dict:
            pass
        try:
            json.loads(value)
        except:
            self._error(value, "Invalid JSON")

app = Eve(validator=JsonValidator)

I know, it's very nasty... Maybe introduce 'converter' so it can be done in one hit?

Add an insert hook:

def multi_request_json_parser(documents):
    for item in documents:
        if 'my_json_field' in item.keys():
            item['my_json_field'] = json.loads(item['my_json_field'])

app.on_insert_myendpoint += multi_request_json_parser
