Hello Guys,
I was having issues cause some empty arguments were treated as "" (emtpy)
instead of none, so the filter() was translating the query as 'where
column=""' instead of "where column is NULL", so I'm trying to write some
validation in my add method in my classes:
class Someclass(Object):
add(self, **kwargs)
tbl = self.__tablename__
for key in table.c.keys():
if key not in kwargs:
kwargs.setdefault(key, None)
value = kwargs.get(key)
if not value:
kwargs[key] = None
mapper(Someclass, any_table)
Is that possible? if so, can a parent class be written in that way so child
classes will include this validation of the argument based on the table
columns as part of the add method?
Sorry for the questions but I'm new on both worlds (Python and SQLAlchemy)
Thanks and kind regards
