  • Why are you not closing the database connection before shutdown?

    Why are you not closing the database connection before shutdown?

    We (our team) were trying with your library, and stumbled on this "missing" feature.

    It's important to close the connections for a truly graceful shutdown. Was that a project decision? Didn't you just think about it?

    More important: would you be willing to receive a proposal for this implementation?

  • Remove __all__ in __init__

    Remove __all__ in __init__

    Hi, I noticed this project uses __all__ for most of its modules. However, in fastapi_plugins/__init__.py I see __all__ = [] which causes my editor to warn with things like 'RedisSettings' is not declared in __all__. I decided to simply remove __all__ from there since it is optional. Alternatively, I could combine __all__ from each of the imported modules.

    What do you think?

  •  AttributeError: 'State' object has no attribute 'REDIS'

    AttributeError: 'State' object has no attribute 'REDIS'

    Pytest API testing does not work if a function has a cache dependency.

    Here is the example

    @router.post("/login/", response_model=Token)
    async def login(form_data: OAuth2PasswordRequestForm = Depends(),
                    cache: aioredis.Redis = Depends(fastapi_plugins.depends_redis)):
                    ...
                    await cache.setex("SomeKey", 300, "SomeValue")
    
    
        @pytest.mark.asyncio
        async def test_login_view_pass(self, client):
            data = UserInput(**self.__generate_data())
            await user_create(data)
            response = await client.post(f"{settings.API_VERSION}/users/login/",
                                         data={"username": data.username,
                                               "password": data.password},
                                         headers={"Content-Type": "application/x-www-form-urlencoded"})
            assert response.status_code == status.HTTP_200_OK
    
    
    self = <starlette.datastructures.State object at 0x7f10ceccd610>, key = 'REDIS'
    
        def __getattr__(self, key: typing.Any) -> typing.Any:
            try:
                return self._state[key]
            except KeyError:
                message = "'{}' object has no attribute '{}'"
    >           raise AttributeError(message.format(self.__class__.__name__, key))
    E           AttributeError: 'State' object has no attribute 'REDIS'
    
    /usr/local/lib/python3.8/site-packages/starlette/datastructures.py:672: AttributeError
    

    Is there any way to solve this issue ?

  • aioredis version issue: `AttributeError: module 'aioredis' has no attribute 'create_redis_pool'`

    aioredis version issue: `AttributeError: module 'aioredis' has no attribute 'create_redis_pool'`

    aioredis does not import anymore create_redis_pool method in its __init__ at least after v1.3.1 see here.

    Unfortunately fastapi-plugins is still using that method in _redis.init() and it defines aioredis>=1.3.* in its setup.py see here

    That can cause to raise the following exception in case aioredis > 1.3.1 has been installed in your system

    AttributeError: module 'aioredis' has no attribute 'create_redis_pool'
