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.

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.

import os def run_django_quickstart(): project_name = 'myproject' app_name = 'myapp' print(f"Creating Django project '{project_name}'...") os.system(f'django-admin startproject {project_name} .') os.chdir(project_name) print(f"Creating Django app '{app_name}'...") os.system(f'python manage.py startapp {app_name}') # Modify settings.py to include the new app settings_path = os.path.join(project_name, 'settings.py') with open(settings_path, 'r') as f: content = f.readlines() insert_index = -1 for i, line in enumerate(content): if 'INSTALLED_APPS' in line: insert_index = i + 1 break if insert_index != -1: content.insert(insert_index, f" '{app_name}',\n") else: print("Warning: Could not find INSTALLED_APPS in settings.py. Please add manually.") with open(settings_path, 'w') as f: f.writelines(content) print("Applying migrations...") os.system('python manage.py makemigrations') os.system('python manage.py migrate') print("Creating superuser (username: admin, email: admin@example.com, password: password).

Debug
Known issues
breakingDjango 6.0 dropped support for Python versions older than 3.12. Projects on Python 3.11 or earlier must upgrade their Python environment before upgrading to Django 6.0.
fix
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.
affects: >=6.0
breakingIn Django 6.0, URL patterns in `urlpatterns` now explicitly require `path()` or `re_path()`. Implicit string syntax for URL patterns is no longer supported.
fix
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)`.
affects: >=6.0
breakingSeveral previously deprecated APIs were removed in Django 6.0, including `django.utils.translation.ugettext()` (use `gettext()` instead) and specific form renderers like `DjangoDivFormRenderer`.
fix
Consult the Django 6.0 release notes and deprecation timeline to identify and replace removed APIs. For translation, use `gettext()` instead of `ugettext()`.
affects: >=6.0
gotchaFailing to run `makemigrations` and `migrate` after model changes or adding new apps is a common mistake that leads to database schema inconsistencies.
fix
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.
affects: All versions
gotchaIncorrect relative imports within Django apps can cause 'ModuleNotFoundError' issues. Django's import system relies on the project structure.
fix
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`.
affects: All versions
breakingDjango 6.0 requires a minimum of SQLite 3.31.0. Older SQLite versions are no longer supported.
fix
Ensure your system's SQLite library is updated to version 3.31.0 or newer, especially in production environments.
affects: >=6.0
Errors
Common errors & fixes
ModuleNotFoundError: No module named 'django'
The Django package is not installed in the active Python environment, or the incorrect Python interpreter/virtual environment is being used for the project.
fix
Activate your project's virtual environment (if used) and install Django: `pip install django` or `python -m pip install django`.
django.core.exceptions.ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
Django's settings module is not correctly specified, often when running a script outside the standard manage.py context or when the DJANGO_SETTINGS_MODULE environment variable is not set or points to a wrong location.
fix
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`.
django.db.utils.IntegrityError: UNIQUE constraint failed: app_model.field_name
An attempt was made to save a new object or update an existing one with a value for a unique field that already exists in the database, violating a UNIQUE constraint.
fix
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.
YourModel.DoesNotExist: YourModel matching query does not exist.
A `get()` query on a Django model's manager did not find any object matching the given lookup parameters in the database.
fix
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.
No changes detected
Django's `makemigrations` command did not find any differences between your models and the current migration files, often because the app is not listed in `INSTALLED_APPS`, the `migrations` directory is missing, or there's a typo in the model definition.
fix
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.
