#28668: Add ON CONFLICT support to QuerySet.bulk_create() -------------------------------------+------------------------------------- Reporter: Tom Forbes | Owner: Tom | Forbes Type: New feature | Status: assigned Component: Database layer | Version: master (models, ORM) | Severity: Normal | Resolution: Keywords: | Triage Stage: Accepted Has patch: 1 | Needs documentation: 0 Needs tests: 0 | Patch needs improvement: 0 Easy pickings: 0 | UI/UX: 0 -------------------------------------+------------------------------------- Changes (by Дилян Палаузов):
* Attachment "on_conflict_ignore.patch" added. The on_conflict_ignore.patch adds on_conflict='ignore' to QuerySet.bulk_create and empowers bulk_create optionally to send post_save signals, when the ID of the inserted object is known to bulk_create. For postgresql bulk_create offers in addition to retrieve the IDs of the newly inserted objects, when using on_conflict='ignore' and, with a second query, to find the PKs pf the supplied objs that were already in the databse. When supported by the backend (so not Oracle), on_conflict='ignore' is added to bulk_create() in django.db.models.fields.create_forward_many_to_many_manager.ManyRelatedManager._add_items, making ManyRelatedManager.add() thread-safe, possibly resolving #19544. -- Ticket URL: <https://code.djangoproject.com/ticket/28668> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
