Hello all,
I want to save files from my activity so that I can retrieve them from
the future instances of my activity and also want them to be visible
in the journal. So, I am planning to save them in the datastore. And
is planning to retrieve them using the datastore.find() function in
the future instances of my activity. However, the following link
mentions --
http://wiki.sugarlabs.org/go/Development_Team/Almanac/sugar.datastore.datastore
that using the function is not very reliable except with the
activity_id key.
I don't think that warning is particularly helpful. I'd ignore it.
As, I want to access all such files with a special property which I
saved from the previous versions of the activity, I can't just rely on
the activity_id thing. So, what can be a good solution for it. Would
using the find function be fine. Kindly give your suggestions. Just
repeating my requirements-
1. The files should be visible in the journal.
2. They should be accessible from within the future instances of the
activity.
'activity_id' is actually the activity instance id, which differs
whenever you start a fresh copy of the activity, so that's not what
you want. But using the 'activity' key should work fine, since this is
your activity's bundle id (e.g. 'my.organization.MyActivity'):
