Today, when doing business, this problem always occurs, I studied for half a day, found that my code strictly according to

Try

***

exception

***

Else

***

This format to write, why still wrong?

So all kinds of Google, what comments off @transaction.commit_manually see where the mistake, everything tried.

Until I found this post: Http://stackoverflow.com/questions/9955321/django-transaction-managed-block-ended-with-pending-commit-rollback

Ma but Ah, it turns out that there are database operations before returning to the view.

1retval = Render_to_response ('***/***.html',{2                 'form': Form,3                 'nav_active':'Active',4 },context)5 Transaction.commit ()6         returnretval

This will be OK.
