I'm writing a ZClass for a generic SQL table editor. It detects the format of the table, and generates a sortable table with add/edit/delete functions. The ZClass itself is tied to a Database Adaptor that has to be hardcoded to connect to a certian database. This is bad, I need each instance to point to a different database. I cannot find any way to change what database the DA connects to in python or by any other method. If you change the connection string, it affects all of the instances of the zClass. I'm at a loss for ideas on how to do this properly. Right now I have a Psycopg DA inside of the ZClass. Anyone have any hints? Put a (dummy) DA inside your product (containing your ZClass). This way, you can add Z SQL methods to your ZClass.
In the ZInstance constructor, add a DA (with the same id as the dummy) in the created instance (or *much* better) ensure, each instance can acquire a DA with this id. Dieter
