Hello,
I just solved it, and went with a @property. On Build I have:
@property
def values(self):
return Value.objects.filter(grouping__build=self)
and on the Value I have:
@property
def build(self):
return self.grouping.build
This way I stay backwards compatible and didn’t even have to change my
templates and such. Thanks for the tips, though!
Best,
Gergely
