I have to admit I'm not sure how the API should look like. I'll probably take a look at a few examples in other projects. Maybe you can update the PR to show the current signature of the bulk update. |

Yeah I understand. I mean you've done this:
def bulk_update(self, objects: typing.List[MODEL], ...):

In this case Model will be undefined because it has been defined after bulk_update

So, maybe we need to add it to |

yes, I have an old PR which is doing it but It's not really the best way but it can give you some ideas. Feel free to take a look at that and start your own. |
