Hi,
using SVN revision 15440 I get some weird behaviour:
Part of my model looks like this:
---------
from django.contrib.gis.db import models
class Address(models.Model):
uuid = UuidField(primary_key=True)
readable = models.CharField(max_length=200)
geo = models.GeometryField()
def save(self, *args, **kwargs):
self.readable, self.geo = geocode(self.readable)
super(Address, self).save(*args, **kwargs)
class Corporation(models.Model):
uuid = UuidField(primary_key=True)
name = models.CharField(max_length=200)
class Branch(models.Model):
uuid = UuidField(primary_key=True)
address = models.OneToOneField(Address)
corporation = models.ForeignKey(Corporation)
---------
In the admin interface I use
---------
class AddressAdmin(admin.ModelAdmin):
readonly_fields = ('geo',)
admin.site.register(Address, AddressAdmin)
class BranchInline(admin.StackedInline):
model = Branch
fields = ('address',)
class CorporationAdmin(admin.ModelAdmin):
inlines = [BranchInline]
fields = ('name',)
admin.site.register(Corporation, CorporationAdmin)
--------
Now for the weird part:
Add a corporation via admin interface, click save, works as expected.
Open the corporation again, in the inlined branch, add a new address,
click save, works as expected.
Then: open that corporation a third time, no matter what you do (delete
a branch, add another, change anything) clicking save returns this error:
MultiValueDictKeyError at

u'branches-MAX_NUM_FORMS': [u''], u'branches-1-address': [u'']}>"
I'm worried about the mention of branches.uuid -- this shows up
nowherein the generated form (only a select 'branches-0-address' with
the uuids of available addresses).
Playing around with fk_name on the inline admin brought me nothing but
error messages…
This only seems to concern the InlineModelAdmin. When I use seperate
ModelAdmin-s, everything works.
Where should I look for the bug? Might it be my custom UUID-field? (but
it seems to work…)
Cheers,
