Hi all!
I'm refactoring a database schema but I need it to mantain reverse
compatibility with older versions of our software - using views.
But, to avoid confusion to other developers, new tables have two
underscores as a prefix, like:
class Base(object):
@declared_attr
def __tablename__(cls):
return "__%s" % to_python_case(cls.__name__)
Now I want to add column prefixes too. I know I can append to this Base
object:
__mapper_args__ = dict(
column_prefix='_'
)
But, when I inherit this new base on classes that I need to use
__mapper_args__, column names probably won't have prefixes. Any ideas,
perhaps an event listener to prepend the underscore into *all* column names?
Cheers,
Richard.
