redirect_uri is lost

[brandoncc]

I have a scenario where I need to redirect to a different url for creating users, as I don't want it to happen automatically in the same controller action as a user signing in. I have tried attaching a redirect_uri to my oauth request to Github but it gets lost in the sorcery code.

First request url (correct, includes /create):

http://0.0.0.0:3000/oauth/github?redirect_uri=http%3A%2F%2F0.0.0.0%3A3000%2Foauth%2Fcallback%2Fcreate%3Fprovider%3Dgithub

Next request in network tab (/create is gone):

https://github.com/login/oauth/authorize?client_id=***&display=&redirect_uri=http%3A%2F%2F0.0.0.0%3A3000%2Foauth%2Fcallback%3Fprovider%3Dgithub&response_type=code&scope=&state=

I have followed the flow of the code and it appears that authorize_url doesn't have any way to support this currently. Is there a recommended way to use separate controller actions for signing in and registering?

By the way, I changed my oauth controller action to:

def oauth
  login_at(auth_params[:provider], redirect_uri: auth_params[:redirect_uri])
end
