Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It is currently at version 6.0.3 and follows a time-based release schedule with feature releases approximately every eight months. Long-term support (LTS) releases occur every two years and receive security and data loss fixes for three years.
pip install DjangoVerified import paths — ran on the pinned version, not inferred.
This quickstart guides you through setting up a new Django project and application, running migrations, and creating an admin superuser. It modifies `settings.py` to include your new app and provides instructions to start the development server.
Upgrade your Python installation to 3.12, 3.13, or 3.14. Verify all dependencies are compatible with the new Python version before upgrading Django.
Refactor your `urlpatterns` to use `path()` for simple URL patterns and `re_path()` with regular expressions where needed. E.g., change `url(r'^api/users/(?P<id>\d+)/$', views.user_detail)` to `path('api/users/<int:id>/', views.user_detail)` or `re_path(r'^api/users/(?P<id>\d+)/$', views.user_detail)`.Consult the Django 6.0 release notes and deprecation timeline to identify and replace removed APIs. For translation, use `gettext()` instead of `ugettext()`.
Always run `python manage.py makemigrations` to create migration files for your model changes, and then `python manage.py migrate` to apply those changes to your database.
Use absolute imports starting from the app name (e.g., `from myapp.models import MyModel`) or explicit relative imports (e.g., `from .models import MyModel`) where appropriate, ensuring the app is correctly registered in `INSTALLED_APPS`.
Ensure your system's SQLite library is updated to version 3.31.0 or newer, especially in production environments.
Activate your project's virtual environment (if used) and install Django: `pip install django` or `python -m pip install django`.
Ensure the DJANGO_SETTINGS_MODULE environment variable is set to your project's settings file (e.g., `export DJANGO_SETTINGS_MODULE=myproject.settings`) or run Django commands using `python manage.py`.
Ensure that the data being saved adheres to unique constraints by checking for existing records before saving, updating the existing record if intended, or by implementing `try-except IntegrityError` blocks for robust error handling.
Use a `try-except YourModel.DoesNotExist` block to gracefully handle cases where the object is not found, or in views, use the `get_object_or_404()` shortcut to automatically raise an Http404 exception.
Verify that your app is included in `INSTALLED_APPS` in `settings.py`, ensure a `migrations` directory with an `__init__.py` file exists within your app, and double-check your model definitions for any unsaved changes or typos.
