ImproperlyConfigured at /admin/polls/poll/add/ 'model' is a required attribute of 'PollAdmin.inlines[0]'.

[Adrian Paul Ciobanita]

Hello, i've been playing with Django 1.5.4 for some TDD tutorials, examples, and tried to also do the tutorial : https://docs.djangoproject.com/en/1.4/intro/tutorial02/#adding-related-objects

BUT i keep receiving this error, as suggested in the Subject: 

ImproperlyConfigured at /admin/polls/poll/add/ 

'model' is a required attribute of 'PollAdmin.inlines[0]'.

This is my admin.py content:
from django.contrib import admin                                                                                                                                    

from polls.models import Choice, Poll

   

   

class ChoiceInline(admin.StackedInline):

    mode = Choice

    extra = 2

    

class PollAdmin(admin.ModelAdmin):

    fieldsets = [

            (None, {'fields': ['question']}),

            ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),]

    inlines = [ChoiceInline]

    list_display = ('question', 'pub_date', 'was_published_recently')

    search_fields = ['question']

    list_filter = ['pub_date']

  

admin.site.register(Poll, PollAdmin)

If i change admin.py and i'm left with:

admin.site.register(Poll)

Then i have no problem whatsoever with accessing, creating, deleting polls.

Can any of you please point out in the right direction? It get's really frustrating. :(

Below is the output/stacktrace from the server:

Thx in advance.

Kind regards.

Rename the attribute "mode" to model in the ChoiceInline.
