.
I am trying to create a many to many relationship between two classes
(Promotion and Category).
When I add "categories = models.ManyToManyField(Category)" to the
Promotion class I get an errror saying "Category is not defined".
However, when I add "promotions = models.ManyToManyField(Promotion)"
to the Category Class it works fine!
This is driving me crazy, as a newbie it's not easy to diagnose where
the problem lies. I've been very impressed with the documentation,
review etc of Django - but after 24 hours of not getting too far, I'm
getting rather frustrated.

from django.db import models

class Promotion (models.Model):
promo_headline = models.CharField(maxlength=400, core=True)
promo_sbody = models.TextField(help_text="This is for a short
description about the offer")
promo_lbody = models.TextField(help_text="This if sfor a long
description about the offer")
pub_date = models.DateTimeField()
categories = models.ManyToManyField(Category)
start_date = models.DateTimeField(core=True)
expiry_date = models.DateTimeField()
promoter_name = models.ForeignKey(Promoter,
edit_inline=models.TABULAR)
is_multi_takeup = models.BooleanField(help_text="Tick if the offer
can be taken up by the same person more than once")
takeup_url = models.URLField(help_text="URL where the offer will be
taken up")
question_email = models.EmailField(core=True, help_text="where
questions about this offer will be sent")
terms_conditions = models.TextField(core=True)
def __str__(self):
return self.promo_headline
class Category (models.Model):
category_name = models.CharField(maxlength=400)
def __str__(self):
return self.category_name
class Admin:
pass
