Hello,
I have problems with many-to-many model. Look at this please:
from django.core import meta
class Model1(meta.Model):
attr1 = meta.CharField(maxlength=10)
class META:
admin = meta.Admin()
class Model2(meta.Model):
attr2 = meta.ManyToManyField(Model1)
class META:
admin = meta.Admin()
When I try to make new Model2, I get this error:
>>> from django.models.test import model2s
>>> b=model2s.Model2()
>>> b.save()
---------------------------------------------------------------------------
exceptions.AttributeError Traceback (most
recent call last)
/usr/home/michal/www/django-server/valmez_info/<console>
/usr/local/lib/python2.4/site-packages/django/utils/functional.py in

----> 3 return args[0](*(args[1:]+moreargs),

/usr/local/lib/python2.4/site-packages/django/core/meta/__init__.py in
method_save(opts, self)

991 # First, try an UPDATE. If that doesn't update anything, do
an INSERT.
--> 992 pk_val = getattr(self, opts.pk.attname)
993 pk_set = bool(pk_val)
994 record_exists = True
AttributeError: 'Model2' object has no attribute 'id'
But if I add field to Model2 class, like:
class Model2(meta.Model):
something = meta.CharField(maxlength=10)
attr2 = meta.ManyToManyField(Model1)
class META:
admin = meta.Admin()
And then make the new Model2 in shell, everything works fine:
>>> from django.models.test import model2s
>>> b=model2s.Model2(something="foo")
>>> b.save()
(No errors here)
Does anybody tell me what I make wrong please?
Thank you for any advice
Regards
Michal
