[BangPypers] SQLAlchemy and 'non-trivial' default values for a column

[Dhruv Baldawa]

Then I guess you are doing it the wrong way. You should only have a single
session object (unless working with multiple databases simultaneously). The
object should be binded with whatever connection is required.


if PRODUCTION:
    engine = create_engine(...)
else:
    engine = create_engine(...)

session = sessionmaker(bind=engine)

then import session from whichever module you have added the above code. I
don't know how you are doing the model-based queries, if you have someother
way of querying models you can follow that, the concept and method still
remains the same.

Configurations can be controlled by an optional command-line argument or
environment variable or a flag, its upto you. I run 4 different
configurations for my app using command-line arguments.
