python - Attaching extra information to model instance - django -

I have a dynamic model that I want to attach an additional piece of information, depending on the environment according to the example (The user who is logged in) For this reason, I do not want to do this at the database level.

Is that okay? Or there are problems that I'm not predicting

"Type 'foo' or 'bar'" "def __init __ (auto, type): self.type = type

views.py

FooChat (FooOrBar): "" "" "never saved the database" def __init __ (self, foo_or_bar): self .__ dict__ = foo_or_bar .__ dict __copy () def check_type ( Self, external_type): If external_type == 'foo': self.is_foo = any other is true: self.is_foo = false foos_or_bars = FooOrBar.objects.all () foochecks = map (FooCheck, foos_or_bars) in foochecks For foocheck: foocheck.check_type ('foo')

Additional credit questions: Is there a more efficient method of calling a method on many items i.e. the last with some clever To change the line?

OK, it does not work to destroy a Trying FooOrBar objects about a complaint

throws

  / OperationalError on such a table: test_FooCheck  

get around this I just fuoraba Inherit'm not going to happen, but if anyone has any suggestions on better ways to do it so I'd be interested in hearing it
