TypeError: 'class Meta' got invalid attribute(s): indexes

[Dennis Kornbluh]

Going through the Django tutorial, now at part 5, section "Running tests". Followed the directions precisely, copy/pasted to create polls/test.py, After running

$ python manage.py test polls

got a stacktrace (http://dpaste.com/2XP5QZ7) ending with TypeError: 'class Meta' got invalid attribute(s): indexes

Totally stumped. Everything has worked up to this point.

Hi Dennis,

"indexes" is a new thing in the upcoming Django version. I'm fairly
certain that you accidentially used Django's development version at some
point while going through the tutorial.

Could you please paste your models.py and the migration files Django
created for you when you ran "manage.py makemigrations".

What Django version are you using? Meta.indexes is a new feature in Django 1.11 -- are you using it in your models?

Hi Markus,

Yes, you're right. When I started the tutorial I got the latest source from github, but then I uninstalled and reinstalled 1.10 using pip. Something remained from 1.11, perhaps in the database?

import datetime

from django.db import models

from django.utils import timezone

class Question(models.Model):

    question_text = models.CharField(max_length=200)

    pub_date = models.DateTimeField('date published')

    def __str__(self):

        return self.question_text

    def was_published_recently(self):

        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

class Choice(models.Model):

    question = models.ForeignKey(Question, on_delete=models.CASCADE)

    choice_text = models.CharField(max_length=200)

    votes = models.IntegerField(default=0)

    def __str__(self):

        return self.choice_text

from django.db import migrations, models

import django.db.models.deletion

class Migration(migrations.Migration):

    initial = True

    dependencies = [

    ]

    operations = [

        migrations.CreateModel(

            name='Choice',

            fields=[

                ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),

                ('choice_text', models.CharField(max_length=200)),

                ('votes', models.IntegerField(default=0)),

            ],

            options={

                'indexes': [],

            },

        ),

        migrations.CreateModel(

            name='Question',

            fields=[

                ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),

                ('question_text', models.CharField(max_length=200)),

                ('pub_date', models.DateTimeField(verbose_name='date published')),

            ],

            options={

                'indexes': [],

            },

        ),

        migrations.AddField(

            model_name='choice',

            name='question',

            field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='polls.Question'),

        ),

    ]

Aha! Should've grepped the whole project for indexes. How do I "undo" this?

Thanks,

Dennis

I think I solved the problem by commenting out the two options elements. If there's a better way to address this, please let me know.

Thanks,

Dennis
