Hello,
I'm using a current SVN checkout of django an I'm having difficulties
creating a custom field.
class ForeignKeyAX(models.ForeignKey):
__metaclass__ = models.SubfieldBase
description = "ForeignKey field prepared for Ajax Autocompletion"
def __init__(self,*args,**kwargs):
self.kunde_rel=False
if kwargs.has_key('kunde_rel'):
self.kunde_rel = kwargs.pop('kunde_rel')
super(ForeignKeyAX, self).__init__(*args,**kwargs)
with this, I get the folowing error:
KeyError at /path//id/
'ip'
Request Method: GET
Request URL: http://localhost:8000/path/id/
Django Version: 1.3 beta 1 SVN-15308
Exception Type: KeyError
Exception Value:
'ip'
Exception Location:
/path-to_djanog/django/db/models/fields/subclassing.py in __get__,
line 96
and further down:
/home/roman/devel/django-trunk/django/db/models/fields/subclassing.py in __get__
89.
def __init__(self, field):
self.field = field
def __get__(self, obj, type=None):
if obj is None:
raise AttributeError('Can only be accessed via an instance.')
96. return obj.__dict__[self.field.name]
'ip' is not contained in obj.__dict__. Like the other foreignkey
fields its there as ip_id.
What am I doing wrong? How can I get this going?
BTW: When I ommit the line:
__metaclass__ = models.SubfieldBase
Everything works fine. But then other things I want to do like
overriding to_python will not work as far as I understand.
Please help.
Best regards
Roman
