python manage.py runserver
Visit http://127.0.0.1:8000/
If there is an error that claims polls
is missing, you'll need to install my django-polls
app.
# I had to use pip3 instead of pip to get this to work
pip3 install --user path/to/django-polls/dist/django-polls-0.1.tar.gz
After changing a model, database migrations will need to be generated and applied.
python manage.py makemigrations polls
python manage.py migrate
To preview what sort of database query is generated by any given migration, run (replacing 0001
with the migration number of your choice)...
python manage.py sqlmigrate polls 0001
Import modules, apps and models to fiddle with them.
python manage.py shell
For example, test adding, updating and deleting items from the database via models.
python manage.py shell
>>> from polls.models import Question
>>> from django.utils import timezone
>>> q = Question(question_text="What's up?", pub_date=timezone.now())
>>> q.save()
>>> q.choice_set.create(choice_text='The sky', votes=0)
>>> c = q.choice_set.create(choice_text='Just hacking again', votes=0)
>>> c.delete()
>>> q.choice_set.count()
