Hello everyone,
I want to access one (and only one) spreadsheet of a user from within
a task of a google app engine application.
This code works in a normal request but not in a task:
client = gdata.spreadsheet.service.SpreadsheetsService()
gdata.alt.appengine.run_on_appengine(client)
client.email = 'anad...@gmail.com'
client.password = '...'
client.source = '...'
client.ProgrammaticLogin()
feed = client.GetWorksheetsFeed(spreadKey) #
With the Google Web interface the user can give access to
'anad...@gmail.com' for this unique spreadsheet and everything than
goes fine for a normal request.
I understand that ProgrammaticLogin is normally for 'installed
applications' because with Web apps it's better to ask the
authorization on-line... But what strategy should we use in a task?
I need to make some treatments on the spreadsheet and these can nicely
be parted in tasks. Like that, I have all the benefits of tasks...
I could copy all the feeds that I need during a normal request
somewhere in the datastore and later read at this place from the
tasks... But this put a lot of workload on the normal request that
could otherwise be spread on the different tasks.
ProgrammaticLogin has some advantage over AuthSub because I found
problems when trying to limit the authorization scope to everything in
only one spreadshead. And thus with authSub, it even not work in a
normal request.
Could someone give me ideas to solve this situation?
Thanks in advance,
Michel
