You want to asynchronously update a user's email and then fetch the updated user object. Which code correctly does this?
AUser.objects.filter(pk=1).aupdate(email='new@example.com') user = User.objects.aget(pk=1)
Bawait User.objects.afilter(pk=1).aupdate(email='new@example.com') user = await User.objects.aget(pk=1)
Cawait User.objects.filter(pk=1).update(email='new@example.com') user = await User.objects.get(pk=1)
DUser.objects.filter(pk=1).update(email='new@example.com') user = User.objects.get(pk=1)
Step-by-Step Solution
Solution:
  1. Step 1: Use async update method

    'aupdate' is the async version of 'update' and must be awaited.
  2. Step 2: Fetch updated user asynchronously

    Use 'await' with 'aget' to get updated user object asynchronously.
  3. Final Answer:

    Await 'aupdate' and then await 'aget' to fetch updated user -> Option B
  4. Quick Check:

    Async update + async get with await = await User.objects.afilter(pk=1).aupdate(email='new@example.com') user = await User.objects.aget(pk=1) [OK]
Quick Trick: Use 'await' with 'aupdate' and 'aget' for async update and fetch [OK]
Common Mistakes:
MISTAKES
  • Using synchronous 'update' without await
  • Not awaiting 'aget' after update
  • Mixing sync and async ORM calls
