Well, I put the code in line, thus:
class BolForm(forms.Form):
- q = Scac.objects.all()
- scaclist = []
- for x in q:
--- scaclist.append((x.code, x.name))
- scac = forms.ChoiceField(
----- label=u'Ocean Carrier', choices=scaclist)
- bill_of_lading = forms.CharField(
----- label=u'Bill of Lading #', max_length=50)
- bol_type = forms.ChoiceField(
----- label=u'Type of B/L', choices=BOL_CODE_QUALIFIERS)
It worked. But is there a better way?
