OneToOneField being ignored in Django Admin

[andrew_rust@…]

I have the following models set up:

---

from django.db import models
import datetime

class Ref(models.Model):

ref = models.CharField(max_length=200)

def unicode(self):

return self.ref

class Poll(models.Model):

ref = models.OneToOneField(Ref, verbose_name='reference')
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')

def unicode(self):

return self.ref

def unicode(self):

return self.question

class Choice(models.Model):

poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)

def unicode(self):

return self.choice

class Vote(models.Model):

site = models.CharField(max_length=200)
choice = models.ForeignKey(Choice)
votes = models.IntegerField()
date = models.DateTimeField('date voted')

def unicode(self):

return self.site

from django.contrib import admin

class ChoiceInline(admin.TabularInline):

model = Choice
extra = 5

class PollAdmin(admin.ModelAdmin):

fieldsets = [

('Poll Information', {

'fields': ('ref', 'question')

}),
('Date information', {

'fields': pub_date

}),

]
inlines = [ChoiceInline]
list_display = ('question', 'ref', 'pub_date')
list_display_links = ('question', 'ref')
list_per_page = 25
search_fields = question
save_on_top = True

admin.site.register(Poll, PollAdmin)

When trying to run syncdb against this i get the following error....

If i change the OneToOneField to a ForeignKeyField then syncdb runs with no problems.
