How do I create a new datastore object?
In addition to the [[1]write_file()] method, which allows sugar's activity code to save your activity by creating a datastore object, you can explicitly create datastore object in your activity code using the datastore.create() method. The following code shows how a new datastore object is created and then actually written to the datastore. Other sections will discuss how this datastore object can actually be assigned to files and populated with useful metadata.
#This method creates a datastore object that will be saved for later use by this activity.
def _create_ds_object(self):
#my_dsobject is of type datastore.DSObject
my_dsobject = datastore.create()
# ... you can put any code to change your datastore file and metadata here ...
#Persist this newly created datastore object in the datastore for later access.
datastore.write(my_dsobject)
return my_dsobject
