Django Authentication Forms in Django 5.1

The django.contrib.auth.forms module is not deprecated in Django 5.1. It's a valid and important part of Django's authentication system that provides built-in forms for common authentication tasks.

Built-in Authentication Forms

According to the Django 5.1 documentation, the authentication system provides several built-in forms located in django.contrib.auth.forms, including:

• PasswordResetForm: Used for initiating the password reset process
• SetPasswordForm: Used for setting a new password (typically after a reset)

These forms are still fully supported and are the recommended way to handle password reset functionality rather than creating custom forms from scratch.

Testing Password Reset Functionality

Testing the default password reset functionality is worthwhile, especially when you're customizing templates or workflows. While there isn't a dedicated section in the documentation specifically for testing password reset functionality, you can test it using Django's standard testing tools.

Your approach of importing and testing these forms is valid:

PYTHONCopied
from django.contrib.auth.forms import PasswordResetForm, SetPasswordForm

Implementation in Django 5.1

For implementing password reset functionality in Django 5.1, you would typically use the built-in class-based views:

PYTHONCopied
from django.contrib.auth import views as auth_views

urlpatterns = [
    path(
        "password_reset/",
        auth_views.PasswordResetView.as_view(),
        name="password_reset",
    ),
    path(
        "password_reset/done/",
        auth_views.PasswordResetDoneView.as_view(),
        name="password_reset_done",
    ),
    path(
        "reset/<uidb64>/<token>/",
        auth_views.PasswordResetConfirmView.as_view(),
        name="password_reset_confirm",
    ),
    path(
        "reset/done/",
        auth_views.PasswordResetCompleteView.as_view(),
        name="password_reset_complete",
    ),
]

These class-based views have superseded the older function-based views that were deprecated in Django 1.11.

Recommendation

Continue using the django.contrib.auth.forms module as it's still the correct approach. For testing, focus on:

1. Testing that the password reset workflow functions correctly
2. Testing that emails are sent correctly
3. Testing that users can successfully reset their passwords
4. Testing edge cases like invalid tokens or expired links

If you're customizing the templates or adding additional functionality, those customizations should be tested as well.
