Hi,
look at this example:
{{{
class A(models.Model):
foo = models.CharField(max_length=32)
# b = models.ManyToManyField('B', through='A_B')
b = models.ManyToManyField('B')
class B(models.Model):
bar = models.CharField(max_length=32)
class A_B(models.Model):
a = models.ForeignKey('A')
b = models.ForeignKey('B')
}}}
Then i run:
{{{
>>> from django.core.serializers import serialize
>>> serialize('python', A.objects.all())
[{'pk': 1L, 'model': u'testapp.a', 'fields': {'foo': u'eeeee', 'b':
[1L]}}]
}}}
This is OK.
Now I change models to this:
{{{
class A(models.Model):
foo = models.CharField(max_length=32)
b = models.ManyToManyField('B', through='A_B')
# b = models.ManyToManyField('B')
class B(models.Model):
bar = models.CharField(max_length=32)
class A_B(models.Model):
a = models.ForeignKey('A')
b = models.ForeignKey('B')
}}}
I serialize it:
{{{
>>> from django.core.serializers import serialize
>>> serialize('python', A.objects.all())
[{'pk': 1L, 'model': u'testapp.a', 'fields': {'foo': u'eeeee'}}]
}}}
'b' is missing in output...
