Ubuntu 8.04
Using sqlite3
All was working fine until the "StackedInLine"
My admin.py:

from mysite.polls.models import Poll, Choice
from django.contrib import admin

class ChoiceInLine(admin.StackedInLine):

model = Choice
extra = 3

class PollAdmin(admin.ModelAdmin):

#fields = ['pub_date', 'question']
fieldsets = [

(None, {'fields': question}),
('Date information', {'fields': pub_date,

'classes':collapse}),

]
inlines = [ChoiceInLine]

admin.site.register(Poll, PollAdmin)

[dc]

Inline not InLine
