Django object creation or table insertion

[susanodd]

ADD MORE DESCRIPTION TO CLARIFY WHAT THIS IS ABOUT
THE FOLLOWING IS A CODE SNIPPET BUT IS INSUFFICIENT

@vanlummelhuizen

        for sense_translation in old_sense.senseTranslations.all():
            # iterate over a list because the objects will be removed
            for translation in sense_translation.translations.all():
                sense_translation.translations.remove(translation)

Are these calls to remove(...) necessary here given that they concern either vanilla many-to-many relationships or a through-model have ForeignKey fields with on_delete=models.CASCADE, e.g. GlossSense?

If the removes are not necessary, could all calls to delete of individual objects, be replaced to the delete of a few querysets? Or even one queryset, if the on_delete=models.CASCADE does the rest?

Has this code actually deleted the object, or merely removed it from the table?

There is some discrepancy between accounts online of

• creating and object using the constructor

• inserting a row into a table

When said object is deleted, is it actually deleted or just removed from the table?

Normally, an object may not have been deleted if other objects still refer to it

Senses can be shared.
