2536	Mutually referential many-to-one relationship AddManipulator fails.	anonymous	Adrian Holovaty	"There is an example of this given here:

http://www.djangoproject.com/documentation/models/mutually_referential/

It hasn't been updated to reflect magic removal changes, but seems pretty straightforward:
{{{
class Parent( models.Model ):
    name = models.CharField(maxlength=100, core=True)
    bestchild = models.ForeignKey(""Child"", null=True, related_name=""favoured_by"")

    class Admin:
        pass

class Child( models.Model ):
    name = models.CharField(maxlength=100)
    parent = models.ForeignKey(Parent)

    class Admin:
        pass
}}}
When playing with these models in the shell, everything seems to work fine.  When I use the admin interface and click to add a child I get:

'bool' object has no attribute 'get'

with the full stack trace:
{{{

Adding a Parent works until you try and add the bestchild attribute.
