Pydantic 模型 w Fastapi 看不到属性

Question

schemas.py

import pydantic as _pydantic
import datetime as _dt

class _UserBase(_pydantic.BaseModel):
    email = str


class UserCreate(_UserBase):
    hashed_password = str

    class Config:
        orm_mode = True

main.py

import fastapi as _fastapi
import fastapi.security as _security
import sqlalchemy.orm as _orm
import services as _services
import schemas as _schemas

app = _fastapi.FastAPI()


@app.get("/")
def get():
    m = _schemas.UserCreate.schema_json()
    return m

当我去 localhost:8000/ 它 returns:

"{\"title\": \"UserCreate\", \"type\": \"object\", \"properties\": {}}"

而且我也看不到 swagger 文档中的请求正文。它是空的。

正如您在 official pydantic tutorial 中看到的那样，您应该使用类型注释，而不是将类型分配为 class 变量：

class _UserBase(_pydantic.BaseModel):
    email: str
