This follows the
[http://www.djangoproject.com/documentation/models/m2m_intermediary/
m2m_intermediary pattern], but with associations, not between two
different models, but between pairs of instances of the *same* model.
Given this Person model:
{{{
class Person(models.Model):
first_name = models.CharField(maxlength = 100)
last_name = models.CharField(maxlength = 100)
}}}
and associating pairs of persons, while adding some data:
{{{
class Association(models.Model):
person = models.ForeignKey(Person, related_name='friend_of')
associate = models.ForeignKey(Person, related_name='friends')
some_data = models.IntegerField()
}}}
the admin interface for these models works correctly.
Now, to be able to add Associations while editing Persons, add
edit_inline and core to Association fields.
When adding them to both !ForeignKey fields:
{{{
class Association(models.Model):
person = models.ForeignKey(Person, related_name='friend_of',
core=True, edit_inline=models.TABULAR)
associate = models.ForeignKey(Person, related_name='friends',
core=True, edit_inline=models.TABULAR)
dummy = models.IntegerField()
}}}
this error comes out:
{{{

When adding edit_inline and core to the first !ForeignKey field only:

associate = models.ForeignKey(Person, related_name='friends')
