[But he top-posted, so I moved his stuff down below the question]. A bit of fiddling about with the interpreter in a manage.py shell session reveals all: In [11]: from django.db.models import Field In [12]: f = Field() In [13]: f.get_internal_type() Out[13]: 'Field' In [14]: from django.db.models import IntegerField In [15]: i = IntegerField() In [16]: i.get_internal_type() Out[16]: 'IntegerField' And, of course, there's always In [17]: help(i.get_internal_type) which tells you: """ Help on method get_internal_type in module django.db.models.fields: get_internal_type(self) method of django.db.models.fields.IntegerField instance """ Not terrifically helpful, but at least the signature tells you no arguments are required ... regards Steve --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
