Hi James,
Yes, it workedd :)
I created the object outside the method and called it at every transaction
point in the loop and when there is rollback, it rollbacks all the queries.
Thanks James

Hi James,
Thanks for your feedback. I basically want to rollback that query where I
update the db. Basically I want to rollback all the updates that were made
during that transaction. Tried out the method of custom Exception as
suggested by Tom but somehow my bad luck that it is still not worki
Hi Tom,
I tried the code that you posted but somehow it is giving*
UnexpectedNoAssetSpecificationException at /reservation/ *error. I am not
sure but when this exception is raised, then control is not going to
class UnexpectedNoAssetSpecificationException(Exception):
pass
and when it goes
> asset_spec =
AssetSpecification.objects.filter(asset_id_id=inventory,utilized_value=0).values_list('asset_id',
flat=True)
> trans = transaction.savepoint() // Here I am trying
not to commit the code and store it in transaction.

Hi Tom,
All these conditions are to be verified before data received from the form
is saved in database.
I tried this Exception method but when the control goes to except block,

Hi Tom,
If you see then in *if *block, I am creating my savepoint. At any point of
time, if the condition is not met and control goes to *else* block then I
want to rollback all the changes that are saved in transaction and redirect
it to some other page and not commit anything to db. I am able
