mfatemipour opened a new issue, #66845:
URL: https://github.com/apache/airflow/issues/66845
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.2.1
### What happened and how to reproduce it?
I implemented a custom connection where I want the host, port, login, and
password fields to always have constant values. To achieve this, I overrode the
get_connection and aget_connection methods and injected those constant values.
This approach works correctly for synchronous calls within my hook (i.e.,
when running on a worker). However, it does not behave as expected in
asynchronous contexts (i.e., when running in the triggerer). In those cases,
the connection fields appear to be empty instead of using the values I set.
### What you think should happen instead?
I guess the root cause is in this helper function:
``` python
#
providers/common/compat/src/airflow/providers/common/compat/connection/__init__.py
async def get_async_connection(conn_id: str) -> Connection:
from asgiref.sync import sync_to_async
if hasattr(BaseHook, "aget_connection"):
return await BaseHook.aget_connection(conn_id=conn_id) #
hard-coded class
return await sync_to_async(BaseHook.get_connection)(conn_id=conn_id) #
hard-coded class
```
Although aget_connection is a @classmethod, calling it through the literal
BaseHook class short-circuits the MRO — Python dispatches straight to
BaseHook's implementation and the subclass override is never consulted.
