我们从Python开源项目中，提取了以下33个代码示例，用于说明如何使用google.appengine.ext.db.ListProperty()。
def decode_list_property(obj, prop, value): if value is None: return [] # there is an issue with large ints and ListProperty(int) AMF leaves # ints > amf3.MAX_29B_INT as floats db.ListProperty complains pretty # hard in this case so we try to work around the issue. if prop.item_type in (int, long): for i, x in enumerate(value): if isinstance(x, float): y = int(x) # only convert the type if there is no mantissa # otherwise let the chips fall where they may if x == y: value[i] = y return value
