I think @JostCrow should have a look as well. have only some remarks-questions after reading and testing your code.

this will be evaluatied upon loading open-inwoner. Should be populated in the init

[annashamray]

I thougth it would be ok, since django querysets are lazy and should not be executed before running. Locally I tried loading OIP main page (with and without logging as a user) and there were no DB queries to Invite table.
Or did I misunderstand your comment?

[alextreme]

I think you indeed misunderstood. Doing this means afaik executing the queryset when starting/reloading runserver, the queryset won't be executed when instantiating the form. In my experience you need to make your queryset a callable, in that case it should work as expected.

However it could be that my knowledge is rusty, I noticed that they have an example in the Django documentation which does the same: https://docs.djangoproject.com/en/4.0/topics/forms/modelforms/#a-full-example

We also use this pattern for the Plan form. Should I leave it as it is or change it everywhere?

[alextreme]

Lets leave it as is. I've tested adding a plantemplate on the testenvironment and this worked so I was incorrect, sorry!
