This is the kind of thing I have been wondering about: what is going on under
the hood?
I was simply doing what the manual told me to do - even if I wasn't sure what
it
wanted. The manual needs to be updated.

Subject: Re: Runnning my new app
This is a concept that you have to get a firm grasp of.
There is a file "layout.html" that contains all of the base HTML that you might
want on every page in your site. It has a templating instruction {{include}}
which is where each of your individual view files will get inserted.
If you recall the default "index.html" file, you should have seen at the top
"{{extend 'layout.html'}}". This is what tells web2py to take your index.html
file and insert it into the layout.html file.
What you also should have seen is in controllers/default.py:
def index():
"""
example action using the internationalization operator T and flash
rendered by views/default/index.html or views/generic.html
"""
return dict(message=T('Hello World'))
When you visit "/welcome/default/index" in your browser, it looks for the app
"welcome, then "default.py" in your controllers file and then "def index()" in
default.py. You will see that index() returns a variable "message='Hello
World'". "message" is sent to the view file views/default/index.html and is
available like this: {{=message}}. The default index.html file includes some
other content but you should be able to find {{=message}} in there somewhere.
Try editing "message" to 'Good bye world'. Or try moving {{=message}} to a
different position in index.html and see what happens.
