I'm actually writing a dynamic importer.
Basically when the program starts it queries all the loaded modules for
a certain package. It then stores the module and class information in a
database and then when a certain view is called the specific data
required is loaded by calling importlib.import_module('module.class').
This then populates the view with the required data.
Basically the idea is to be able to display any data required without
having to tightly couple the view code to a specific model type.
Thanks for the help.
