OK, more insight.
This appears to be a figment of the testing framework.
I didn't mention that I also had a file tests.py and the duplicate
problem is generated when the model that holds the doctests is
imported into tests.py. (I agree that the test code shown below
shouldn't sit in a model doctest)
So, to recreate this behavior, create a models.py that looks like
this:
def MyModel(models.Model):
"""
>>> u=User.objects.create_user('test2','[EMAIL PROTECTED]')
>>> u.email='new'
>>> u.save()
"""
anyfield = models.BooleanField()
COUNT = 0
def user_pre_save(sender, instance, signal, *args, **kwargs):
global COUNT
r = random.randint(1,50)
print 'pre_save: count: %s random: %s' %(COUNT, r)
COUNT +=1
dispatcher.connect(user_pre_save, signal=signals.pre_save,
sender=User)
Then create a tests.py and add this import (that's all you need):
from myproject.models import MyModel
You'll get the behavior I displayed earlier. I'll see if I can figure
out what is causing this.
