KeyError: 'NAME' when using SSO_USE_ALTERNATE_W003

[dqd]

Hello and first of all, thank you for your great Django SSO plugins.

After I installed django_google_sso and django_github_sso together on the latest version of Django 5.1, I got W003 warnings. As described in the documentation, this is expected and I should use this setting to silence original Django check and run an alternate check:

SILENCED_SYSTEM_CHECKS = ["templates.W003"]
SSO_USE_ALTERNATE_W003 = True

However, when SSO_USE_ALTERNATE_W003 is set to True, the app crashes for me:

Exception in thread django-main-thread:
Traceback (most recent call last):
  File "/usr/local/lib/python3.12/site-packages/django_github_sso/checks/warnings.py", line 29, in register_sso_check

ImportError: cannot import name 'check_for_template_tags_with_the_same_name' from 'django.core.checks.templates' (/usr/local/lib/python3.12/site-packages/django/core/checks/templates.py)

During handling of the above exception, another exception occurred:

KeyError: 'NAME'

It looks like a bug to me.

The workaround is to add NAME to TEMPLATES setting, like here:

TEMPLATES = [
    {
        "NAME": "django",  # <-- added
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [],
        "APP_DIRS": True,
        "OPTIONS": {
            "context_processors": [
                "django.template.context_processors.debug",
                "django.template.context_processors.request",
                "django.contrib.auth.context_processors.auth",
                "django.contrib.messages.context_processors.messages",
            ],
        },
    },
]

According to the Django documentation, NAME is optional (it defaults to the name of the module defining the engine class), so I still think this is a bug.
