Unable to figure out the syntax to import a model from a different app now that ModelForms are in play

[dgets]

Running into the same problem that I originally had from #5 again, now that I've switched from using models & forms separately in subadd to utilizing ModelForms to avoid redundancy. This is in trying to find the proper solution to #11, which I just closed, as everything seems to be working, except for accessing the query of the Substance records.

See also:

lasttime/recadm/forms.py

Line 5 in 682db29

sub = forms.ForeignKey('subadd.Substance', on_delete=models.CASCADE)

...which I have replaced with sub = forms.ModelChoiceField(queryset=subadd.Substance), along with at least a dozen other variations (including variations of from imports).

Try:

from subadd.models import Substance
[...]
sub = forms.ModelChoiceField(queryset=Substance.objects.all())

Later, you may want to change that queryset dynamically, for instance to filter by the currently-logged-in user. A pretty solid example of doing this is here:

How exceedingly odd, I could swear that I tried exactly that. I bet I tried every combination of things like it, but never matched up those 2 lines properly. m(

Thank you for your input, sir. It is much appreciated.
