Hi Folks,
What's our current thinking on how a developer should go about
establishing and using what I'll call a preference, essentially a single
persistent value with a well-known name (in this case, I'm wanting to
persist the last directories chosen for import and export)?
We've got lots of well-known collections living in
parcels/osaf/app/__init__.py, perhaps that's the appropriate place for
preferences? It doesn't feel quite right to me...
I'm sending this question to the list instead of asking one person or
another because
A) I think there might be different opinions, and
B) I'm hoping someone will write up a detailed example so that knowledge
can live on in the list, not just my brain :)
The simplest thing that would work:
class PrefsForMyParcel(schema.Item):
some_pref = schema.One(sometype, defaultValue=something)
# ... other preferences
def installParcel(parcel, oldVersion=None):
PrefsForMyParcel.update(parcel, "prefs")
Accessing preferences can then be done via:
schema.ns("my.parcel", view).prefs.some_pref
