I'm using Django 1.2.3 and South 0.7.3.
I am trying to convert my app (named core) to use Django-South. I have a custom model/field that I'm using, named ImageWithThumbsField. It's basically just the ol' django.db.models.ImageField with some attributes such as height, weight, etc.
While trying to ./manage.py convert_to_auth core I receieve South's freezing errors. I have no idea why, I'm Probably missing something...
I am using a simple custom Model:
from django.db.models import ImageField
class ImageWithThumbsField(ImageField):
def __init__(self, verbose_name=None, name=None, width_field=None, height_field=None, sizes=None, **kwargs):
self.verbose_name=verbose_name
self.name=name
self.width_field=width_field
self.height_field=height_field
self.sizes = sizes
super(ImageField, self).__init__(**kwargs)
And this is my introspection rule, which I add to the top of my models.py:
from south.modelsinspector import add_introspection_rules
from lib.thumbs import ImageWithThumbsField
add_introspection_rules(
[
(
(ImageWithThumbsField, ),
[],
{
"verbose_name": ["verbose_name", {"default": None}],
"name": ["name", {"default": None}],
"width_field": ["width_field", {"default": None}],
"height_field": ["height_field", {"default": None}],
"sizes": ["sizes", {"default": None}],
},
),
],
["^core/.fields/.ImageWithThumbsField",])
This is the errors I receieve:
! Cannot freeze field 'core.additionalmaterialphoto.photo'
! (this field has class lib.thumbs.ImageWithThumbsField)
! Cannot freeze field 'core.material.photo'
! (this field has class lib.thumbs.ImageWithThumbsField)
! Cannot freeze field 'core.material.formulaimage'
! (this field has class lib.thumbs.ImageWithThumbsField)
! South cannot introspect some fields; this is probably because they are custom
! fields. If they worked in 0.6 or below, this is because we have removed the
! models parser (it often broke things).
! To fix this, read http://south.aeracode.org/wiki/MyFieldsDontWork
Does anybody know why? What am I doing wrong?
