Hi everyone,
What's the trick to getting a ModelChoiceField to use the first object
in a QuerySet as the initial value to get rid of -?
If I do:
qs = Model.objects.all()
my_field = forms.ModelChoiceField(queryset=qs, initial=qs[0])
I still get -- as the first choice.
TIA,
Bran
Solved: ModelChoiceField(empty_label=None)

appropriate CSS styling will render really nice forms as is, with the
exception of the help_text. I even think that could be fixed without
any major rework, just a change in the as_p() string
from
def as_p(self):

I need to use a db backend (Sybase) which is not supported by Django.
I don't need to use the Django ORM but would like Django to maintain a
pool of open db connections so that I don't have to make a new
connection every time I need to run a query (similar functionality

Ok - I think I should actually be using initial - but still haven't
gotten that to actually work. I'm trying something like this:
In models.py
