Can't get contextmanager-style resource to work: #920
Description
Running version 4.43.0
No combination of calling the provider, or calling init_resources before or after calling the provider calls the __enter__ method. shutdown_resources doesn't work either:
In [22]: from dependency_injector import containers, providers
...:
...: class DatabaseConnection:
...: def __init__(self):
...: self.connected = False
...:
...: def __enter__(self):
...: print(f"Connecting db")
...: self.connected = True
...: return self
...:
...: def __exit__(self, exc_type, exc_val, exc_tb):
...: print("Closing connection")
...: self.connected = False
...:
...:
...: class Container(containers.DeclarativeContainer):
...:
...: config = providers.Configuration()
...: db = providers.Resource(
...: DatabaseConnection,
...: )
...:
In [23]: c = Container()
In [24]: c.db()
Out[24]: <__main__.DatabaseConnection at 0x7cb818aa2180>
In [25]: c.init_resources()
In [26]: c = Container()
In [27]: c.init_resources()
In [28]: c.db()
Out[28]: <__main__.DatabaseConnection at 0x7cb7e6116210>
In [29]: c.db().connected
Out[29]: False
In [30]: c.db.init().connected
Out[30]: False
In [31]: c = Container()
In [32]: c.init_resources()function-type resources work fine, but I don't think they can be shutdown. Creating a contextmanager from a function with @contextlib.contextmanager doesn't work either.
Tested with the latest version, can't get that to work either
