Changes in Django 2.2 mean that the auto-created primary key changes
(https://docs.djangoproject.com/en/3.2/releases/3.2/#customizing-type-of-
auto-created-primary-keys) throw the associated warnings, as the Tutorial
Part 2 doesn't adjust for these.
Reproduction:
* in a new virtualenv, `pip install django==3.2.2`
* generate a new template project `django-admin startproject mysite .`
* confirm the generated `settings.py` doesn't mention
DEFAULT_AUTO_FIELD
* run though the tutorial, up to and including
https://docs.djangoproject.com/en/3.2/intro/tutorial02/#creating-models
* attempt to `python manage.py makemigrations polls`
* get errors
{{{
System check identified some issues:
WARNINGS:
polls.Choice: (models.W042) Auto-created primary key used when not
defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the
PollsConfig.default_auto_field attribute to point to a subclass of
AutoField, e.g. 'django.db.models.BigAutoField'.
polls.Question: (models.W042) Auto-created primary key used when not
defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the
PollsConfig.default_auto_field attribute to point to a subclass of
AutoField, e.g. 'django.db.models.BigAutoField'.
