What are some useful Django shell commands?

Django shell commands are powerful tools for interacting with your Django application. Some useful commands include:

1. python manage.py shell - Opens an interactive Python shell with your Django environment loaded.
2. python manage.py makemigrations - Creates new migrations based on the changes you made to your models.
3. python manage.py migrate - Applies migrations to your database.
4. python manage.py createsuperuser - Creates a superuser account for the admin interface.

Can you give me an example of using the shell to query the database?

Sure! After running python manage.py shell, you can import your models and query the database. For example:

from myapp.models import MyModel
results = MyModel.objects.all()
for item in results:
    print(item)
``` This will print all instances of `MyModel`.

What about running custom management commands?

You can create custom management commands by adding a management/commands directory in your app. Then, create a Python file for your command. For example:

from django.core.management.base import BaseCommand

class Command(BaseCommand):
    help = 'My custom command'

    def handle(self, *args, **kwargs):
        self.stdout.write('Hello from my custom command!')
``` You can run it with `python manage.py my_custom_command`.

Are there any commands for testing?

Yes! You can use python manage.py test to run your tests. It will discover and run all tests in your project.
