I've hit a wall trying to make a fairly simple tkinter form oriented application using SQL-Alchemy in keeping the tkinter widgets and the sql-alchemy objects in synchronization. Google searches haven't provided any benefit, so I turn to the mailing list.
Does anyone have any code samples, best practices, or could recommend other open source programs that use tkinter and sql-alchemy that correctly demonstrate how to work with the pair? The issues I've been having are typically due to implicit string conversions, input validation, converting strings back to the sql data type (date, datetime, boolean, integer, decimal.decimal), and synchronizing updates to the screen vs updates to the sql-a object. I've tried a few methods now, including using Variables (ie: IntVar, StringVar, etc), tracing those variables, and now I'm working through creating a class which would inherit from Variable but perform the type conversions. Oddly enough session management has been a breeze.
