Question

In tutorial here I get down to where you run was_published_recently and I get this error:

ImproperlyConfigured at /admin/polls/poll/
PollAdmin.list_display[2], ‘was_published_recently’ is not a callable or an attribute of ‘PollAdmin’ or found in the model ‘Poll’.
Request Method: GET
Request URL: /admin/polls/poll/
Django Version: 1.4
Exception Type: ImproperlyConfigured
Exception Value:
PollAdmin.list_display[2], ‘was_published_recently’ is not a callable or an attribute of ‘PollAdmin’ or found in the model ‘Poll’.
Exception Location: C:\Python27\lib\site-packages\django\contrib\admin\validation.py in validate, line 38

here is my code:

from polls.models import Poll

from django.contrib import admin

from polls.models import Choice

class ChoiceInline(admin.TabularInline):
  model = Choice
  extra = 3

class PollAdmin(admin.ModelAdmin):

   fieldsets = [
    (None,               {'fields': ['question']}),
    ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
   inlines = [ChoiceInline]

class PollAdmin(admin.ModelAdmin):
   # ...
   list_display = ('question', 'pub_date', 'was_published_recently')

  admin.site.register(Poll, PollAdmin)

here is my poll model

  from django.db import models

  class Poll(models.Model):
   question = models.CharField(max_length=200)
   pub_date = models.DateTimeField('date published')


  class Choice(models.Model):
   poll = models.ForeignKey(Poll)
   choice = models.CharField(max_length=200)
   votes = models.IntegerField()

  class Poll(models.Model):
   # ...
   def __unicode__(self):
    return self.question

  class Choice(models.Model):
    # ...
    def __unicode__(self):
    return self.choice

Answer 1

Can you update your question with your Poll model?

It looks like you may have made a mistake when adding the was_published_recently method to your Poll model in the Playing with the API step in Tutorial 1.

Update:

Now that you’ve posted your model, it does look as if you’ve missed out the was_published_recently method. Go back over tutorial 1 and add it in.

Secondly, don’t include each model more than once in models.py – the second one will replace the first.
