How to post unstructured json data as Form parameter?

[baseplate-admin]

Hi everyone,

I was making a POST request using curl

curl -X 'POST' \
  'http://127.0.0.1:9000/api/v1/anime/5/episodes' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer qhdVcdJPzIonD8Ze' \
  -H 'Content-Type: multipart/form-data' \
  -F 'episode_number=1245321' \
  -F 'episode_name=fads' \
  -F 'episode_summary=gasd' \
  -F 'providers={"hello":"world"}'

Heres my views.py

@router.post("/{int:anime_id}/episodes", response=EpisodeGETSchema, auth=AuthBearer())
def post_individual_episodes(
    request: HttpRequest,
    anime_id: int,
    episode_number: int = Form(...),
    episode_name: str = Form(...),
    episode_cover: UploadedFile | None = File(default=None),
    episode_summary: str = Form(...),
    providers: dict[str,str] | None = Form(default=None),
) -> EpisodeModel:
    user: CustomUser = request.auth
    if not user.is_superuser:
        raise HttpResponse(
            "Superuser is required for this operation",
            status=HTTPStatus.UNAUTHORIZED,
        )
    # Set this at top
    # Because if there is no anime_info_model with corresponding query
    # theres no point in continuing
    anime_info_model = get_object_or_404(AnimeModel, pk=anime_id)

    payload = {
        "episode_number": episode_number,
        "episode_name": episode_name,
        "episode_cover": episode_cover,
        "episode_summary": episode_summary,
        "providers": json.loads(providers),
    }

    instance = EpisodeModel.objects.create(
        **{key: value for key, value in payload.items() if value}
    )
    anime_info_model.episodes.add(instance)

    return instance

But it raised:

{
  "detail": [
    {
      "loc": [
        "form",
        "providers"
      ],
      "msg": "value is not a valid dict",
      "type": "type_error.dict"
    }
  ]
}

Hey vitalik,

I will have to ask one more small question.

Do you know how to validate both keys and values?
This should work :

{"hello": "world"}

This should not :

{"hello":1}

I have tried to do :

class JsonObjectValidator(Schema):
        json : Json[AnyStr]

But it didn't work.

What i want to validate is dict[str,str]
