How do I get the application title of a Google AppEngine app from within that app

Question

Under the application settings page in the Administration console, it is possible to specify a name for the application, AFAIK this is used in the login page when using the users API to login.

I would like to be able to use this information within an application, currently, the title is also specified in a separate configuration file, but configuration repetition is something I would like to avoid if at all possible.

Is there some way for a GAE application to determine the "Application Title"?

Oh, also, I am using python.

Answer 1

I believe that's not possible, unfortunately.

Using the app enine console, I could not find the application title on the environment variables.

Answer 2

There's actually a way to do it, but it might be a little too much on the hacky side.. you can get the title (ab)using the users API like this:

>>> from google.appengine.api import users
>>> import urllib
>>> url = users.create_login_url()
>>> url_dict = dict((p.split('=') for p in url.split('&')))
>>> urllib.unquote_plus(url_dict['ahname'])
'App Engine Console'

I tried it on the App Engine Console linked by jbochi (great link btw, thanks!). Not to sure weather I'd put such code into production, though. Further diving into google.appengine.api.user_service might turn up a saner way.
