Hi all,
I've noticed that a few people are trying to use ClientLogin with one
master account on App Engine, so allow me to explain with a big caveat
up front: this technique can cause auth tokens to be shared by
everyone who uses your App Engine app.
Unless you are using one master account that you want all of your
users to share, please do not use this technique.
First, you'll need to tell your Google Data service client that it is
running on App Engine:
client = gdata.service.GDataService() # or some subclass of
GDataService, like DocsService
gdata.alt.appengine.run_on_appengine(client)
By default, the above modifies the token_store so that all auth tokens
must be associated with a user. When your app has a current_user, the
token is stored in the datastore, if there is no current user, the
token is discarded. I required that tokens be associated with a user
since some parts of your app can stay in memory across requests to
your app and it is possible that you might write your app in a way
that could cause tokens to be used for the wrong user. I've tried to
make it more difficult for you to make such a mistake. If you are
using one shared account, then it is ok for all of your app users to
have access to the same auth token. We can replace the token store
with one that keeps all tokens in memory and does not associate them
with any user:
client.token_store = atom.token_store.TokenStore()
Then use ClientLogin(), or ProgrammaticLogin(), etc.
Let me repeat one more time, after you make this change, and depending
on how your client is initialized, it is possible for auth tokens from
one user to stay in memory and be reused in other requests, so make
sure that you really want all users to see data for this account. I
can't emphasize enough that this modification should only be used in
very limited circumstances.
Thank you,
Jeff
