Python 将函数传递给Dependers时，FastAPI在0x000002B68FBDB100>；处引发"；TypeError：<；生成器对象get_db不是可调用的对象

我得到了:

文件"C:\PythonProjects\myProject\routers\home.py"，第39行， @router.get("/home"，response_class=HTMLResponse)

...

raise TypeError('{！r}不是可调用对象". format(obj)) TypeError:0x 000002 B68 FBDB 100处的生成器对象get_db不是 可调用对象

home.py个

    from fastapi import Depends, APIRouter, Request
    from fastapi.templating import Jinja2Templates
    from sqlalchemy.orm import Session
    from starlette.responses import HTMLResponse
    
    from database import SessionLocal, engine
    from models import Base
    
    router = APIRouter()
    templates = Jinja2Templates(directory="templates", autoescape=False)
    Base.metadata.create_all(bind=engine)
    
    
    def get_db():
        try:
            db = SessionLocal()
            yield db
        finally:
            db.close()

@router.get("/home", response_class=HTMLResponse)
async def all_skills(request: Request, db: Session = Depends(get_db())):
    all = db.query()
    return templates.TemplateResponse("home.html", {"request": request, "show": all})

database.py个

from sqlalchemy import create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

SQL_ALCHEMY_DATABASE_URL = "postgresql://postgres:password@localhost/DatabaseName"

engine = create_engine(SQL_ALCHEMY_DATABASE_URL)

SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)

Base = declarative_base()

main.py个

from fastapi import FastAPI

import models
from database import engine
from routers import home
from starlette.staticfiles import StaticFiles


app = FastAPI()

models.Base.metadata.create_all(bind=engine)

app.mount("/static", StaticFiles(directory="static"), name="static")

app.include_router(home.router)
