I attempted to simplify creation of the response.menu list of tuples by the
following function:
def menu_item(menu_item_text, url, sub_menu=None, ignore=False):
# First element of tuple is the text of the meny item.
retval = list(menu_item_text)
# Second element of the tuple indicates if this menu item is the
# current active one.
retval.append(url == URL())
# Third element is the link to follow when this item is selected.
retval.append(url)
# The fourth item is an optional sub_menu.
if sub_menu:
retval.append(sub_menu)
else:
retval.append([])
retval.append(ignore)
return retval
but when using it like so:
def public_menu():
response.menu += [
menu_item('How it Works', URL('default', 'how_it_works')),
menu_item('Testimonials', URL('default', 'testimonials')),
menu_item('Sign up Now!', URL('default', 'register')),
menu_item('Login' , URL('default', 'login')),
]
if auth.is_logged_in():
logged_in_menu()
else:
public_menu()
I get the error:
