Optional form data about pyfa-converter HOT 6 CLOSED

@fgsalomon, Firstly, Field should be used inside the pydantic model, not Form.

class MyRequest(BaseModel):
    a: str | None = Field(default=None)
    b: str | None = Field(default=None)

    @validator('a')
    def a_must_contain_space(cls, v):
        if not v:
            return v
        if ' ' not in v:
            raise ValueError('must contain a space')
        return v.title()

@app.post("/test")
async def test(data: MyRequest | None = FormDepends(MyRequest)):
    print(data)

Successful sending of the request, if you uncheck the swagger on send empty value buton.

Ooops, my bad. I've fixed this now. However, it seems to me it doesn't change anything.

Yeah, I know I can do that but what I would like is the model to be None when no data is sent:

curl -X 'POST' \
  'http://127.0.0.1:8000/test' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/x-www-form-urlencoded'
"Has form data"%

@fgsalomon,

class MyRequest(BaseModel):
    a: str | None = Field(default=None)
    b: str | None = Field(default=None)

    @root_validator
    def all_is_none(cls, values: dict[str, Any]):
        if all(v is None for v in values.values()):
            raise ValueError("all is none")
        return values

You need it?

i don't understand the essence of your task, first you want to allow None value, now you don't want None value...
