I've already created a ticket that ended up with 'WONTFIX' here <https://code.djangoproject.com/ticket/33770>. Please read it first.
The scenario that led me trying to add that feature: Well, I'v a model that has a primary key and unique field... Every X period of time I've a cron that calls an external API to load updated data and store it in my Django project db. Thing is I want to execute the update query without having to have the pk with me.. I already have the unique field in hand (got it from the API) and it should be enough to identify what object to be updated.. example code that will do so.. *# call external API and load data as list[dict]* *objs = list()* *for record in data:* * # Just create instance of MyModel class with values needed..* * objs.append(MyModel(my_unique_field=data['national_id'], name="New Name"))* *# I expect to do:MyModel.objects.bulk_update(objs, fields=["name"], unique_field="my_unique_field")* The current implementation requires every object to have its primary key set, but, that's not always the case. Also, if the primary key is my-django-project-generated, there's no way AFAIK to get those PKs without having to query them from DB, which will be a very expensive query to run if the data is large. You can find the POC PR here: https://github.com/django/django/pull/15764 I really thing that'd be a very useful update to add. I also have a question about this function: We can't use it to update primary keys.. I'm wondering why ? I want to also add that support to it. -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
