I have played with some menu details and these are my results
First try:
response.menu = [
(T('Home'), False, URL('default','index'), [
(T('Dummy1'), False, URL('default','index'), [],),
(T('Dummy2'), False, None, [],),
(T('Desktop'), False, URL('default','index'), [],
not (request.user_agent().is_mobile or
request.user_agent().is_mobile)),
(T('Mobile'), False, URL('default','index'), [],
request.user_agent().is_mobile),
(T('Tablet'), False, URL('default','index'), [],
request.user_agent().is_tablet),
])
]
*Desktop:*
I have expected and I got: Home | Dummy1 | Dummy2 | Desktop (#1)
*Mobile phone:*
I have expected:
Home | Dummy1 | Dummy2 | Mobile
I got:
Home | Dummy1 | Mobile (#2)
*Tablet:*
I have expected:
Home | Dummy1 | Dummy2 | Tablet
I got:
Home | Dummy1 | Mobile | Tablet (#2, #3)
Now a second try:
response.menu = [
(T('Home'), False, None, [
(T('Dummy1'), False, URL('default','index'), [],),
(T('Dummy2'), False, None, [],),
(T('Desktop'), False, URL('default','index'), [],
not (request.user_agent().is_mobile or
request.user_agent().is_mobile)),
(T('Mobile'), False, URL('default','index'), [],
request.user_agent().is_mobile),
(T('Tablet'), False, URL('default','index'), [],
request.user_agent().is_tablet),
])
]
*Desktop:*
I have expected and I got: Home | Dummy1 | Dummy2 | Desktop (#1)
*Mobile phone:*
I have expected:
Home | Dummy1 | Dummy2 | Mobile
I got:
<empty menu> (#2, #4)
*Tablet:*
I have expected:
Home | Dummy1 | Dummy2 | Tablet
I got:
<empty menu> (#2, #4)
Comments:
#1: Everything works as expected, but only on a desktop pc
#2: Menu items without a link are not displayed on a mobile device
#3: Interesting: a tablet is a "tablet" *and *a "mobile phone"
#4: The empty menu is very confusing. It took some hours to find it out,
because my "real" menu is more complicated.
Maybe #2, #3 and #4 are *features *and not *bugs*, but I think, these
things should be documented or changed.
My proposal: menu items should not become invisible depending on the
device. If somebody wants this behavior he could use the fifth component.
Maybe is_tablet should be True only for tablets and not for mobile phones
too. But in this case there should be not only a mobile.html view but also
a tablet.html. And this would make things more complicated.
