OpenAPI extension parses dataclass validators as body

[Silur]

#from pydantic.dataclasses import dataclass
from pydantic.dataclasses import dataclass

@dataclass
class RegisterBody:
    name: str
    email: str
    password: str

    @validator('name')
    def validate_name(cls, v):
        if len(v) < 5:
            raise ValueError('name must be at leasth 5 characters')

@app.post("/register")
@openapi.body({"application/json": RegisterBody})
@validate(json=RegisterBody)
async def register(request, body):
     return json({})

The code above produces the OpenAPI /docs page to populate a validator_name field in the Swagger UI, while for the actual mode it is not a field. Tried with the builting python dataclasses and the Pydantic wrapper too.

Because "schema" is just schema. It's better to have schemas separately from objects with working business logic. You can inherit classes with business logic from schema objects.

Fix on the way. FYI...

@openapi.body({"application/json": RegisterBody}, validate=True)

is the same as

@openapi.body({"application/json": RegisterBody})
@validate(json=RegisterBody)
