示例1: Indexable
# 需要导入模块: from book import Book [as 别名]
# 或者: from book.Book import commitTransaction [as 别名]
class Indexable(Persistent):
# prepend _v_ to make it volatilive
_v_book = None
def __init__(self):
self._v_book = Book()
self._v_book.addData(self)
def __setattr__(self, name, value):
#only run this if the name is within the current objects attributes
if self._v_book and name not in Persistent.__dict__:
# if the book exists AND
# if the value has changed
# and that attribute is an indexable attribute
# OR we want it to be indexed, however it is not actually in the index (this condition will be caught
# in updateIndexedValue)
if self._v_book and self.__dict__.get(name) != value and name in self.indexableAttrs:
self._v_book.updateIndexedValue(self, name, value)
# save changes
self._v_book.commitTransaction()
Persistent.__setattr__(self, name, value)
