Django 4.0: How to properly handle async views and database transactions with SQLAlchemy?
I'm integrating two systems and I'm relatively new to this, so bear with me. I'm working on a Django 4.0 application where I need to implement some async views that interact with a PostgreSQL database using SQLAlchemy as my ORM. The scenario arises when I try to commit a transaction within an async view. I keep working with the behavior `RuntimeError: Task <Task pending name='Task-1' coro=<MyView.as_view() running at myapp/views.py:20> cb=[<TaskWakeupMethWrapper object>]> got Future <Future pending> attached to a different loop`. Here's a simplified version of my code: ```python from django.http import JsonResponse from django.views import View from sqlalchemy.ext.asyncio import AsyncSession, create_async_engine from sqlalchemy.orm import sessionmaker DATABASE_URL = 'postgresql+asyncpg://user:password@localhost/dbname' engine = create_async_engine(DATABASE_URL, echo=True) async_session = sessionmaker(engine, expire_on_commit=False, class_=AsyncSession) class MyView(View): async def get(self, request): async with async_session() as session: async with session.begin(): result = await session.execute('SELECT * FROM my_table') data = result.fetchall() return JsonResponse({'data': data}) ``` I've tried making sure that I have the correct event loop running by using `asyncio.run()` in my main execution point, but it doesn't seem to solve the question. I also attempted to wrap the `async with` block in an `async def` function, but the behavior continues. What am I missing here? Is there a specific way to handle the database session in Django async views that differs from the traditional synchronous approach? Any insights would be greatly appreciated! For context: I'm using Python on Linux. Has anyone else encountered this? My team is using Python for this application. Any examples would be super helpful.
