pattern for updating a datastore object

Vote count:

I'm wondering what the right pattern should be to update an existing datastore object using endpoints-proto-datastore.

For example, given a model like the one from your GDL videos:

class Task(EndpointsModel):
    detail = ndb.StringProperty(required=True)
    owner = ndb.StringProperty()

imagine we'd like to update the 'detail' of a Task.

I considered something like:

@Task.method(name='task.update',
             path='task/{id}',
             request_fields=('id', 'detail'))
def updateTask(self, task):
    pass

However, 'task' would presumably contain the previously-stored version of the object, and I'm not clear on how to access the 'new' detail variable with which to update the object and re-store it.

Put another way, I'd like to write something like this:

def updateTask(self, task_in_datastore, task_from_request):
    task_in_datastore.detail = task_from_request.detail
    task_in_datastore.put()

Is there a pattern for in-place updates of objects with endpoints-proto-datastore?

Thanks!
