Question

I am using GAE with python and I can ask users to sign in with Google using:

loginURL = (users.create_login_url(self.request.path))

This gives me a link that lets users sign in and get redirected to my site.
However some users do not have a Google ID,
Is there any way to let them sign up for one and be redirected to my site?

I know there is no:

signupURL = (users.create_signup_url(self.request.path))

That is the kind of thing I am looking for, asking the user to sign up and have her quickly redirected when she is done.

Thank you very much for any insight.

Actually, it is possible to direct a user to the subscription page.
It is just a little tricky:

The link you get to sign in looks like this:

https://www.google.com/accounts/ServiceLogin?service=ah&passive=true&continue=https://appengine.google.com/_ah/conflogin%3Fcontinue%3Dhttp://study-wise.appspot.com/login&ltmpl=gm&shdf=ChULEgZhaG5hbWUaCVN0dWR5V2lzZQwSAmFoIhRSjkTO01_PtfPG9VN12NFsbyludCgBMhQrFIvLEm2lqCc65PvVrBca1skQRA

Where in my case: http://study-wise.appspot.com/login is the url of the application.
The shdf appears to be some key google uses to track the request. But I have not found any clues about it

Now the sign up link will be:

https://accounts.google.com/NewAccount?continue=https%3A%2F%2Fappengine.google.com%2F_ah%2Fconflogin%3Fcontinue%3Dhttp%3A%2F%2Fstudy-wise.appspot.com%2Flogin&shdf=ChULEgZhaG5hbWUaCVN0dWR5V2lzZQwSAmFoIhRSjkTO01_PtfPG9VN12NFsbyludCgBMhQrFIvLEm2lqCc65PvVrBca1skQRA&service=ah&ltmpl=gm

The url:

https://www.google.com/accounts/ServiceLogin

Was replaced by

https://accounts.google.com/NewAccount

and

passive=true

Has been removed. As far as I see no other changes have been made.

Here is the python function I wrote:

def login2Subscribe(link):
    return link.replace('https://www.google.com/accounts/ServiceLogin', 'https://accounts.google.com/NewAccount').replace('passive=true', '')

You can use it like this:

viewVals['subscribe'] = login2Subscribe(users.create_login_url("/login"))
