In Django 1.6 and earlier, intermediate models containing more than one

Now that you have set up your :class:`~django.db.models.ManyToManyField` to use

.. versionchanged:: 1.7
Before Django 1.7, inheriting from multiple models that had an ``id`` primary
key field did not raise an error, but could result in data loss. For example,
consider these models (which no longer validate due to the clashing ``id``
fields)::
class Article(models.Model):
headline = models.CharField(max_length=50)
body = models.TextField()
class Book(models.Model):
title = models.CharField(max_length=50)
class BookReview(Book, Article):
pass
This snippet demonstrates how creating a child object overwrote the value of a
previously created parent object::
>>> article = Article.objects.create(headline='Some piece of news.')
>>> review = BookReview.objects.create(
... headline='Review of Little Red Riding Hood.',
... title='Little Red Riding Hood')
>>>
>>> assert Article.objects.get(pk=article.pk).headline == article.headline
Traceback (most recent call last):
File "<console>", line 1, in <module>
AssertionError
>>> # the "Some piece of news." headline has been overwritten.
>>> Article.objects.get(pk=article.pk).headline
'Review of Little Red Riding Hood.'

:pep:`249` does not state whether a cursor should be usable as a context

an unexpected behavior in magic method lookups (`Python ticket #9220`_).
Django 1.7 explicitly added support to allow using a cursor as context
