TypeError: __init__() missing 1 required positional argument: 'strategy' #2
Description
Not sure what I've done wrong, but in our app we get the error TypeError: __init__() missing 1 required positional argument: 'strategy' when running tests. It happens for the first test and seems to be caused by the __init__ method not being patched. It seems to only effect the first test run in our suite as on later tests the __init__ method is patched.
If we add from social_django import views in the __init__.py of our project root then the error doesn't appear. If we remove any social_core backends from out AUTHENTICATION_BACKENDS list then the error doesn't occur. So the issue has a workaround, but I'm just wondering if there is something wrong with our set up.
Here are our versions:
Django==1.11.10
social-auth-app-django==2.1.0
social-auth-app-django-mongoengine==1.0.0
social-auth-core==1.7.0
social-auth-storage-mongoengine==1.0.1
Python 3.6.4
Our settings.py has the following setup:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
...
'social_django_mongoengine',
...
)
AUTHENTICATION_BACKENDS = (
'social_core.backends.facebook.FacebookOAuth2',
...
)
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [TEMPLATE_PATH],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
"django.contrib.auth.context_processors.auth",
'social_django.context_processors.backends',
'social_django.context_processors.login_redirect',
],
"debug": DEBUG,
}
}
]
