I have an opinion about that. For me the /models folders should be renamed to /scripts since it has scripts that are executed in every request. Going on this approach I am only writing model-less (or script-less) apps.
I am now recommending to all of my students and clients to avoid the use of models and go to class based system in modules, now with thread locals object and custom_importer it is very easy to create an application without using any model file. I encourage you to learn more about O.O in Python, then after that you can find a better way to create your web2py applications using modules and classes. -- Bruno Rocha [http://rochacbruno.com.br]
