and i’m trying to create a box where the user can select the month he was born in. What I tried was
MONTH_CHOICES = (
(JANUARY, “January”),
(FEBRUARY, “February”),
(MARCH, “March”),
….
(DECEMBER, “December”),
)

I’m wondering if it’s possible to define a foreign key in a models.py file in Django that is a reference to a table in another app?
In other words, I have two apps, called cf and profiles, and in cf/models.py I have (amongst other things):

title = models.CharField(max_length=255)
and in profiles/models.py I want to ….
I’ve got a Django model with two custom manager methods. Each returns a different subset of the model’s objects, based on a different property of the object.
Is there any way to get a queryset, or just a list of objects, that’s the union of the querysets returned by each manager method?

__init__.py
model1.py
model2.py

Django tends to fill up horizontal space when adding or editing entries on the admin, but, in some cases, is a real waste of space, when, i.e., editing a date field, 8 characters wide, or a CharField, also 6 or 8 chars wide, and then the edit box goes up to 15 or 20 chars.
How can I tell the admin how wide a textbox should be, or the height of a T….
