python social auth load strategy and authenticate user manually with release 0.1.26 - python-social-auth

Question

I used python social auth for social authentication in the last 2 months and it was great.
I needed QQ support, hence installed newest git commit (23e4e289ec426732324af106c7c2e24efea34aeb - not part of a release).
until now i used to authenticate the user using the following code:
# setup redirect uri in order to load strategy
uri = redirect_uri = "social:complete"
if uri and not uri.startswith('/'):
uri = reverse(redirect_uri, args=(backend,))
# load the strategy
try:
strategy = load_strategy(
request=request, backend=backend,
redirect_uri=uri, **kwargs
)
strategy = load_strategy(request=bundle.request)
except MissingBackend:
raise ImmediateHttpResponse(HttpNotFound('Backend not found'))
# get the backend for the strategy
backend = strategy.backend
# check backend type and set token accordingly
if isinstance(backend, BaseOAuth1):
token = {
'oauth_token': bundle.data.get('access_token'),
'oauth_token_secret': bundle.data.get('access_token_secret'),
}
elif isinstance(backend, BaseOAuth2):
token = bundle.data.get('access_token')
else:
raise ImmediateHttpResponse(HttpBadRequest('Wrong backend type'))
# authenticate the user
user = strategy.backend.do_auth(token)
which worked fine.
In the latest release this behaviour has changed, and an exception is raised since the "load_strategy" method has changed.
I can't seem to find any documentation on how to do it with the new release.
Any help would be appreciated!

The last changes in the repository changed the importance of the strategy, instead of being the main entity to perform the authentication, it's just a helper class to glue the framework with the backends. Try with this snippet to load the strategy and the backend:
from social.apps.django_app.utils import load_strategy, load_backend
strategy = load_strategy(request)
backend = load_backend(strategy, backend, uri)
...
user = backend.do_auth(token)
