Django Accounts Framework FDG

A reusable Django authentication and role-management application built with Django REST Framework. It provides email-based accounts, session authentication, activation and password recovery, a custom user model with public UUIDs, user administration, and Django Group-based roles.

Current release: Version 0.2.1 on PyPI. This package supplies a custom user model and is intended primarily for new Django projects.

Features

• Email-based registration, sign-in, sign-out, account activation, and password reset.
• User profile and administrative account APIs.
• A custom accounts.User model with a random, unique public_id UUID for public API references.
• Forced-password-change middleware with configurable protected paths and exemptions.
• Django Groups, multiple roles per user, permission checks, and a Django Admin Role Setup Wizard.
• Configurable project branding, frontend links, activation behavior, supported locales, and email templates.
• Password validation through the host project’s AUTH_PASSWORD_VALIDATORS for account creation and password changes.
• Configurable activation-link expiry and renewal when a new activation link is requested.
• Django system checks for important configuration requirements.

Security boundary: UUIDs are opaque identifiers, not authorization. Each project must still enforce authentication, permissions, and object ownership. The Accounts app does not replace a project's CORS, CSRF, HTTPS, or session-cookie configuration.

Requirements and installation

The package metadata currently declares Python 3.13+, Django 6.x, and Django REST Framework 3.16+. These are declared compatibility ranges, not a claim that all combinations have been independently tested.

To install a local editable copy from the package repository:

python -m pip install -e .

After building a wheel with python -m build, you can also install that wheel into a fresh virtual environment to validate the packaged distribution:

python -m pip install path/to/django_accounts_framework_fdg-0.2.1-py3-none-any.whl

Install the published package from PyPI:

python -m pip install django-accounts-framework-fdg

Import-name note: The installed distribution is named django-accounts-framework-fdg, but the Django application is imported as accounts. Avoid installing another package that uses the same top-level Python module name.

Configure a new Django project

1. Install and configure the custom User model

In your project's settings.py, add the app and set the custom user model before running initial migrations:

INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "rest_framework",
    "accounts.apps.AccountsConfig",
]

AUTH_USER_MODEL = "accounts.User"

If your project already has users and migrations using a different user model, switching to accounts.User is not a drop-in operation. Plan a dedicated data and schema migration instead.

2. Configure middleware

Keep your project's normal Django security, session, CSRF, authentication, and message middleware. Place the Accounts middleware after AuthenticationMiddleware:

MIDDLEWARE = [
    "django.middleware.security.SecurityMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "accounts.force_password_middleware.ForcePasswordChangeMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
]

3. Mount Accounts URLs

In the host project's urls.py:

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path("admin/", admin.site.urls),
    path("api/", include("accounts.urls")),
]

The /api/ mount point is only an example. Accounts' own routes use auth/… and a permissions/ endpoint relative to wherever you mount them. Named URLs let the forced-password middleware identify its essential account exemptions even when the mount point changes. Ensure your frontend calls the corresponding paths.

4. Configure branding and account behavior

Add an application-specific ACCOUNTS_FRAMEWORK dictionary to settings.py:

ACCOUNTS_FRAMEWORK = {
    "SITE_NAME": "Example Application",
    "FRONTEND_URL": "https://app.example.com",
    "SITE_URL": "https://api.example.com/",
    "LOGO_URL": "https://example.com/static/logo.png",
    "SUPPORT_EMAIL": "support@example.com",
    "BRAND_COLOR": "#0F766E",
    "ENABLE_SELF_REGISTRATION": True,
    "REQUIRE_EMAIL_ACTIVATION": True,
    "ACTIVATION_PATH": "/activate-account",
    "PASSWORD_RESET_PATH": "/reset-password",
    "ACTIVATION_TOKEN_EXPIRY_HOURS": 24,
    "PASSWORD_RESET_EXPIRY_HOURS": 2,
    "SEND_WELCOME_EMAIL": False,
    "SUPPORTED_LOCALES": ["en", "fr"],  # Example: choose languages supported by your project.
    "ROLE_PRESETS": [],  # Define the new project's groups/permissions.
    "MANAGER_ASSIGNABLE_ROLES": [],
}

The SUPPORTED_LOCALES value above is an example, not a required default. Configure only locales your project supports; invalid values are reported by the Accounts configuration checks. Passwords are validated against your project’s AUTH_PASSWORD_VALIDATORS, so configure those validators in Django settings as well.

Set up a working Django email backend and sender identity in the host project. Ensure activation and reset paths exist in your frontend. Never commit SMTP credentials, database passwords, or Django secret keys.

5. Run initial setup

With your database configured, run:

python manage.py check
python manage.py migrate
python manage.py createsuperuser

Sign in to Django Admin and open the Role Setup Wizard to create your configured Groups. Business apps should define their own permissions and use user.has_perm("app_label.codename"); keep those domain-specific permission definitions outside Accounts.

Forced password changes: protected paths versus allowed paths

When a signed-in user has must_change_password=True, ForcePasswordChangeMiddleware restricts access until their password is changed. Two settings let each project control the scope:

Setting	Default	Purpose
ACCOUNTS_FORCE_PASSWORD_PROTECTED_PREFIXES	("/",)	Where to enforce the password-change restriction. The default covers the whole website.
ACCOUNTS_FORCE_PASSWORD_ALLOWED_PREFIXES	()	Exceptions that the user may still reach before changing their password.

For example, a project might enforce the rule for API routes while allowing a token-based public download endpoint:

ACCOUNTS_FORCE_PASSWORD_PROTECTED_PREFIXES = (
    "/api/",
)

ACCOUNTS_FORCE_PASSWORD_ALLOWED_PREFIXES = (
    "/api/public-downloads/",
)

With must_change_password=True:

Example request	Middleware behavior
/api/private-data/	Blocked with HTTP 403
/api/public-downloads/file-token/	Permitted past this middleware
/api/auth/change-password/	Permitted by Accounts' built-in account-route exception
/dashboard/	Outside the configured protected scope

Important: Allowed paths do not clear must_change_password; they only bypass this middleware check. Views must still enforce their own authentication, token validation, and permissions. Keep prefix exemptions narrow, because a prefix also exempts all paths underneath it. Necessary built-in account endpoints and static assets are also exempted so users can complete the password-change flow.

Public identifiers and account administration

• accounts.User.public_id is the UUID intended for public account identifiers; internal integer database primary keys remain an implementation detail.
• Administration endpoints that target users accept user_public_id rather than exposing a database ID.
• Django Groups and permissions are referenced by Group name and permission code (app_label.codename), not public numeric IDs.
• A non-superuser holding accounts.manage_users may assign only Groups listed in MANAGER_ASSIGNABLE_ROLES. Keep this allowlist limited to low-privilege roles; the Administrator role is superuser-only to assign. Delegated user management in Django Admin should follow the same restriction.

Representative routes when mounted under /api/:

Endpoint	Purpose
/api/auth/csrf/	Obtain CSRF cookie/token support
/api/auth/register/	Register account
/api/auth/activate/	Activate account
/api/auth/login/, /api/auth/logout/	Session authentication
/api/auth/me/	Current user/profile
/api/auth/change-password/	Change password
/api/auth/password-reset/request/	Start password reset
/api/auth/password-reset/check/	Validate reset flow
/api/auth/password-reset/confirm/	Complete reset
/api/auth/roles/, /api/auth/assign-role/	Roles and assignments
/api/auth/set-active/	User active status
/api/auth/admin-set-password/	Administrative password action

See accounts/urls.py and the corresponding serializers/views for supported methods, request payloads, and permission requirements.

Email templates

The package includes text and HTML templates under:

accounts/templates/accounts/emails/
├── activation_email.html
├── activation_email.txt
├── password_reset_email.html
├── password_reset_email.txt
├── welcome_email.html
└── welcome_email.txt

Confirm these templates are present in the built wheel. The containing Django project must enable app template loading (APP_DIRS=True) or configure equivalent template loaders.

Testing and release preparation

In a newly created Django integration project (with no business-specific apps installed), run:

python manage.py check
python manage.py makemigrations --check --dry-run
python manage.py migrate
python manage.py test accounts

Test registration, session login, activation expiry and resend, password validation and recovery, CSRF/cookies, forced password changes, delegated administrative permissions, and the Role Setup Wizard. Validate against each database engine and Python/Django version you intend to support.

To build and validate the distribution from this repository:

python -m pip install --upgrade build twine
python -m build
python -m twine check dist/*
unzip -l dist/*.whl

Verify that the wheel includes accounts/migrations/ and email templates, and that the metadata contains this README as its long description. Passing package checks does not replace clean-install integration tests.

Scope and compatibility notes

• This package ships a concrete custom User model. Adopt it at project initialization, not as an unplanned replacement for an established user schema.
• The account API's JSON shapes and internal route names are part of its public integration contract.
• The package does not host your frontend, configure SMTP credentials, or automatically manage allowed cross-origin browser requests.
• Migration compatibility: Version 0.2.1 retains a regenerated accounts/migrations/0001_initial.py instead of an incremental 0002 migration. It is intended for fresh databases. Do not assume an existing database migrated under 0.1.0 can upgrade directly; a separate schema/data migration plan is required. Never delete an existing database to upgrade without preserving its data.
• Published release: 0.2.1 on PyPI.
