Crusty, May I ask another question? Remember that global variable we where talking about? Where do you recommend to initialize it if my value is stored in a settings table? Tried to initialize it inside Globals but it sends an error:
sqlalchemy.exc.UnboundExecutionError: Could not locate a bind configured on mapper Mapper|Settings|settings, SQL expression or this Session My guess is that Globals is initialized before database binding, so there must be a place where I can initialize this and any other global variable, isn't it?
