I have some code in my apps.py's ready() method that loads some Oauth providers using the authlib module. Basically I am doing this (apps.py):
from django.apps import AppConfig
from authlib.integrations.django_client import OAuth
from django.core.cache import caches
class ApiConfig(AppConfig):
name = 'api'
def ready(self):
import api.receivers
defaultcache = caches['default']
from .modules.oauth import fetch_token
from .models import OauthProvider, OAuth2Token
oauth = OAuth(fetch_token=fetch_token)
print('settings oauthproviders')
allproviders = OauthProvider.objects.all()
for provider in allproviders:
oauth.register(
name=provider.name,
client_id=provider.client_id,
client_secret=provider.client_secret_decrypted,
access_token_url=provider.access_token_url,
access_token_params=provider.access_token_params,
authorize_url=provider.authorize_url,
authorize_params=provider.authorize_params,
api_base_url=provider.api_base_url,
client_kwargs=eval(provider.client_kwargs),
)
print(OAuth2Token.objects.get(name='enelogic'))
defaultcache.set('oauth', oauth)
#defaultcache.get('oauth') # <--- this line gives error
Error:
Fatal Python error: Cannot recover from stack overflow.

This registers some oauth credentials (info) that can be used using the oauth variable (for example oauth.get_authorization_url() which gets me the authorize URL for that Oauth Provider.
Now, I have a lot of different files (I split my views.py into multiple files). How can I access this oauth variable in those files? I have tried with django caches, but then I get a weird overflow error when I try to access the variable.
How would you recommend?
The oauth class is working fine locally in the file, I just need to transfer it to some other file
Why not extracting this in a separate python file (but still inside of your django app).
# oauth_providers.py
from authlib.integrations.django_client import OAuth
from .modules.oauth import fetch_token
from .models import OauthProvider, OAuth2Token
def register_providers(oauth):
print('settings oauthproviders')
allproviders = OauthProvider.objects.all()
for provider in allproviders:
oauth.register(
name=provider.name,
client_id=provider.client_id,
client_secret=provider.client_secret_decrypted,
access_token_url=provider.access_token_url,
access_token_params=provider.access_token_params,
authorize_url=provider.authorize_url,
authorize_params=provider.authorize_params,
api_base_url=provider.api_base_url,
client_kwargs=eval(provider.client_kwargs),
)
print(OAuth2Token.objects.get(name='enelogic'))
oauth = OAuth(fetch_token=fetch_token)
# apps.py
from django.apps import AppConfig
class ApiConfig(AppConfig):
name = 'api'
def ready(self):
from .oauth_providers import oauth, register_providers
register_providers(oauth)
And now you can use it in your views by simple import
# views.py
from .oauth_providers import oauth
# do whatever with oauth
Yes, there are some caveats it will be a global variable (so don't try to change, I don't think you'll need to) and don't try to import the file in your models.py since this should be imported after the app is ready().
