I'v written a help function to auto create a class, and predefined a
__init__ function, and auto assign_mapper to a table metadata:
def assign_class(class_name, table, **kwargs):
import new
class_ = new.classobj(class_name, (object,), {})
def __init__(self, **kwargs):
for key, value in kwargs.items():
self.__dict__[key] = value
class_.__init__ = __init__
globals()[class_name] = class_
assign_mapper(class_, table, **kwargs)
May be this will be helpful for someone.
How to use it?
trans_cata_desc = Table('trans_cata_desc', engine,
Column('__id__', Integer, primary_key = True),
Column('style_of_cata', String(1), default=''),
Column('cata_id', Integer, default=0),
Column('cata_desc', String(40), default=''),
redefine = True
)
assign_class('TransCataDesc', trans_cata_desc)
