missed the "very detailed post".
what does it mean that you want help with menu comprehension using a
controller ?
The menu can be defined wherever you want. Having it defined in models is
just a shortcut to avoid having to redefine it over and over, because
usually the menu is "fixed".
That being said, response.menu is just a list of tuples, optionally
containing another list as the fourth argument.
The scaffolding app has a pretty extensive menu where you can see the
structure needed to generate the menu.
Basically each item is
(text, active_or_not, html_helper, [childrens])
now, let's forget for a second about:
- active_or_not (it just decorates with an "active" class the element)
- html_helper (you can put whatever you want, but then you'd override the
text part)
usually the menu item is
(text, False, URL('bla', 'bla') , [childrens])
This creates an A() tag, that holds "text" as value, URL('bla', 'bla') as
link, and has submenus (one for each item listed in childrens)
to sum up, to have a menu that basically is
- menu 1
- menu 1.1
- menu 1.2
- menu2
you'd have something like
response.menu = [
('menu 1', False, URL('bla', 'bla'), [
('menu 1.1', False, URL('bla', 'bla')),
('menu 1.2', False, URL('bla', 'bla'))
]),
('menu 2', False, URL('bla', 'bla'))
]
>From there on, it's basic list slicing and dicing with python.
let's say you'd like to "insert" a "menu 1.3" in your controller, so in
that particular page only, a menu 1.3 would be visible....
you'd have to append the new element to the fourth element (the [children]
list) of the first menu.
Remembering that python lists are 0-indexed :
response.menu[0][3].append(
('menu 1.3', False, URL('bla', 'bla'))
)
And voilà.
Clearer ?
