AssertionError in django-allauth settings.py during Django application startup

I'm encountering an AssertionError in my Django application when trying to start the development server. The error occurs in the django-allauth package, specifically in the settings.py file. I've already tried reinstalling django-allauth, checking dependencies, and reviewing my configuration without success.

The error occurs when I try to make the ACCOUNT_EMAIL_VERIFICATION = 'mandatory' instead of "none"

here is the traceback:

My Question: How to fix this error as it shows only when ACCOUNT_EMAIL_VERIFICATION is mandatory if it is none the project runs smoothly.

The error you're encountering is an AssertionError in the django-allauth package when you set ACCOUNT_EMAIL_VERIFICATION to 'mandatory'. This error occurs because the django-allauth package expects certain settings to be configured correctly.

To resolve this issue, you can follow these steps:

  1. Ensure you have installed the latest version of django-allauth. You can use the following command to upgrade to the latest version:

    pip install --upgrade django-allauth

  2. Verify that you have included 'allauth' and 'allauth.account' in the INSTALLED_APPS list in your project's settings.py file:

    INSTALLED_APPS = [
    # other apps...
    'allauth',
    'allauth.account',
    # other apps...
]

  3. Double-check your project's urls.py file to ensure that you have included the necessary URLs for django-allauth:

    urlpatterns = [
    # other URL patterns...
    path('accounts/', include('allauth.urls')),
    # other URL patterns...
]

  4. If you have a custom user model, make sure it is correctly configured in your project's settings.py file. You can specify your custom user model using the AUTH_USER_MODEL setting:

    AUTH_USER_MODEL = 'yourapp.YourCustomUserModel'

  5. Review the other settings related to email verification in your settings.py file. Ensure that you have properly configured settings like EMAIL_BACKEND, ACCOUNT_EMAIL_REQUIRED, and ACCOUNT_EMAIL_VERIFICATION.

    Here's an example configuration for email verification:

    EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_EMAIL_VERIFICATION = 'mandatory'

    Make sure you have a valid email backend configured that matches your email service provider.

  6. If the issue persists, try removing any compiled Python files (.pyc or pycache) from your project directory to eliminate any potential caching issues.

I hop it's work

It appears you are getting an assertion error, caused by the fact that some settings have requirements for other settings which are not fulfilled.

ACCOUNT_EMAIL_VERIFICATION = 'mandatory' also requires ACCOUNT_EMAIL_REQUIRED = True.

You can see the documentation for the configuration options and their requirements.

Looking at your error and the source code for django-allauth it seems to be the following requirement that is not fulfilled:

# If login is by email, email must be required
        assert (
            not self.AUTHENTICATION_METHOD == self.AuthenticationMethod.EMAIL
        ) or self.EMAIL_REQUIRED

This further points to the problem being ACCOUNT_EMAIL_REQUIRED not being set to True.
You can see this post for an example of a valid configuration for email verification.
