Thanks for the reply Michael... I had a hunch this wouldn't be easy to
tackle, but this is more than I can chew at the moment: )
For now, I'll just keeping doing what I'm already doing which is to
instantiate a new class taking the table as an argument, and then within my
class reference the table's attributes most likely to be used (See below).
If there is a more elegant way of doing this, I'm all ears ;)
Thanks!
Class MyGenericTable(object):
def __init__(self, table):
self.tablename = table
@property
def metadata(self):
return DB.instance().metadata
@property
def table(self):
return self.metadata.tables[self.tablename]
@property
def columns(self):
return self.table.c
@property
def c(self):
return self.columns
@property
def *primary_key*(self):
return self.table.primary_key
def select(self, data):
""" my select """
some custom code
def insert(self, data):
""" my insert """
some custom code
