#4633: Unable to serialize a not yet saved model which has many-to-many
relation.

Reporter: Bear | Owner: jacob
Status: new | Component: Serialization
Version: SVN | Keywords: model, serialize, many-to-many
Stage: Unreviewed | Has_patch: 0

If I try to serialize a not yet saved model which has many-to-many
relation, it will raise ValueError while serialize many-to-many field.
for instance:
from django.contrib.auth.models import User
u = User(username="bear", password="bear", email="[EMAIL PROTECTED]")
from django.core import serializers
serializers.serialize("json", [u])
=>
ValueError: <class 'django.contrib.auth.models.Group'> instance needs to
have a
primary key value before a many-to-many relationship can be used.
This makes inconvenient while use ajax in some situation.
