Define JSONType in schematics python

I have problem with python schematics. I am using PostgreSQL database, where one of my columns is of json type. From my code perspective I am using schematics to create Request, but schematics dont have JSONType. So I create StringType with json validator like this



param: StringType = StringType(validators=[json_validator])


Json validator looks like this:



def json_validator(data):
try:
json.loads(data)
return data
except ValueError:
raise ValidationError(u'Given parameter value is not JSON.')


When I insert data through PostgreSQL, there is no problem with json, but when I am trying to save data through postman with post request with body like this:



{
"param": "{"name": "John"}"
}


Saved data in db looks like this:



"{"name": "John"}"


Is there a way how to define JSONType in schematics or how to save json like this:



{"name": "John"}


to database?
