Is there a way to only update certain fields in update()?

[aliakhtar]

Is there an equivalent of exclude_fields() for update() to only update certain fields when update() is called?

I have multiple concurrent requests happening - in each request I only want to update one particular field - but because update() saves the whole model, its possible that there will be race conditions and one request will accidentally overwrite the changes of a previous request, even though they are updating different fields each.

Yeah, it's a clear omission.
In bulk_update you have columns: List to set columns that should be updated.
In QuerySet.update (so Model.objects.update(**kwargs)) you only update params passed as kwargs.

And in 0.10.2 (PR #140) that will be merged this week I added _columns: List[str] to Model.update() where you can pass fields that should be updated (if omitted or empty all fields are updated)
