TransactionManagementError from inside atomic block

I have a method that updates a row in the table.

To avoid race condition, I locked the row using `select_for_update` inside an `atomic` block and doing the update.

This method is called from a celery task.

This works well on my local machine. But when this gets called on my production server (two tasks being picked up by two workers at the same time and therefore trying to access the same row at once), I get: 

`TransactionManagementError('select_for_update cannot be used outside of a transaction.',)`

I checked that to use `select_for_update`, autocommit should be False.

Inside the atomic block `get_autocommit` returns False.

Now on production this must be returning `TRUE`.

What could be the reason?
