Model

Defines databases in: /models/module.py

The Models are loaded 1st within Web2Py processing, before the controllers.
So you can import any global modules/set any global variables here.
The Models are imported in alphabetical order, so we load the files which other modules depend on 1st, hence naming them appropriately:
000_config.py, 01_crud.py, 02_pr.py, 03_gis.py, etc

Controller

Python functions in /controllers/module.py
e.g.

   def list_records():
       items = crud.select(table)
       return dict(items=items)

View

HTML/Javascript templates in /views/module/function.html

• these are normal HTML/JS files with the ability to add in Python code (e.g. variables) surrounded by brackets: {{ interpreted python here }}
• there should be an .html file available for each function in the module (name normally being the same as the function)
• these normally inherit from views/layout.html which also includes the JavaScript from views/*_ajax.html
• if there is no view defined then a default view will be displayed, which will show the values of all the data it can see, but not be formatted nicely

Static CSS/Javascript files are stored in /static
