Method Details

appendKey(self, okey, vkey)

Append referenced object relational data to association data and update association data of referenced class.
Parameters:
okey - Application object's primary key value.
vkey - Referenced object's primary key value.
Overrides:
bazaar.assoc.List.appendKey

loadData(self)

Load association data from database.
Overrides:
bazaar.assoc.List.loadData

See Also: reloadData appendKey

reloadData(self, now=False)

Request reloading association relational data. Referenced class' association data are reloaded, too.

Association data are removed from memory. If now is set to true, then relationship data are loaded from database immediately.
Parameters:
now - Reload relationship data immediately.
Overrides:
bazaar.assoc.List.reloadData
