Could you show the code with your attempt to use atomic?

Hi,
I tried that but, when child_serializer.save() throws an exception, the row
created by parent_serializer.save() at the database is not rolled back.
Kind regards,

You can use transaction.atomic:

Hi,
Say I have a parent and a child model.
And also there is a view which is using DRF serializers to save data
into models.
The saving operation steps are:
First create parent parent object
Then, create child object with parent object relation.
The view code regarding the description above:
parent_data = {
"foo": "bar",
"baz": "bar"
}
parent_serializer = ParentSerializer(data=parent_data)
if parent_serializer.is_valid():
parent_serializer.save()
child_data = {
"parent_id": parent_serializer.data['id'],
"baz": "foo":
"bar": "baz"
}
child_serializer = ChildSerializer(data=child_data)
if child_serializer.is_valid():
child_serializer.save()
if any exception is thrown while child_serializer saving, how to roll
back the parent object, too?
Is there any chance to make this happen in a transaction to roll back
any related record?
Kind regards,
Sencer HAMARAT
