new version:
def assign_class(table, **kwargs):
import new
klass = new.classobj('Class' + table.name.capitalize(), (object,), {})
def __init__(self, **kwargs):
for key, value in kwargs.items():
self.__dict__[key] = value
def __repr__(self):
s = []
for k in self.__class__.c.keys():
value = getattr(self, k, '')
if isinstance(value, unicode):
value = value.encode('gbk')
s.append("%s=%s" % (k, value))
return ','.join(s)
klass.__init__ = __init__
klass.__repr__ = __repr__
klass.table = table
assign_mapper(klass, table, **kwargs)
return klass
Usage:
A = assign_class(tableA)
B = assign_class(tableB, order_by=tableB.c.name)
