Django, OAuth2

Install & Settings

Install django-allauth

1	pip install django-allauth

settings.py

# Specify the context processors as follows:
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # Already defined Django-related contexts here

                # `allauth` needs this from django
                'django.template.context_processors.request',
            ],
        },
    },
]

AUTHENTICATION_BACKENDS = (
    ...
    # Needed to login by username in Django admin, regardless of `allauth`
    'django.contrib.auth.backends.ModelBackend',

    # `allauth` specific authentication methods, such as login by e-mail
    'allauth.account.auth_backends.AuthenticationBackend',
    ...
)

INSTALLED_APPS = (
    ...
    # The following apps are required:
    'django.contrib.auth',
    'django.contrib.messages',
    'django.contrib.sites',

    'allauth',
    'allauth.account',
    'allauth.socialaccount',
    # ... include the providers you want to enable:
    'allauth.socialaccount.providers.kakao',
)

SITE_ID = 1

LOGIN_REDIRECT_URL = "accounts:main"

필자는 django 2.2.1버전으로 진행하였고,

AUTHENTICATION_BACKENDS부터 추가하면 되었다.
