[Zope3-Users] menus, menu items and actions

[Jan-Wijbrand Kolman]

Hi,


I'm working an application that will have some sort of 'main menu' of actions,
that should always be available in the UI of this applications.

So, I register a menu:

  <menu
    id="foo_menu"
    title="The Main Foo Menu"
  />

and a menu item for it:

  <menuItem
    title="Do Bar"
    description="Do Bar In This Application"
    for="*"
    menu="foo_menu"
    action="bar"
    permission="zope.Public"
  />

When rendering the HTML for this menu, the menu item's action is basically used
as  a relative URL (relative to the current location in e.g. a content object
tree).

However, what I would like is to point to a specific URL relative to my
application root - since 'bar' is a specific view on my app.root.

At the moment, I solved it by implementing a custom menu class, subclassing
BrowserMenu:

  from zope.app.publisher.browser.menu import BrowserMenu
  class FooMenu(BrowserMenu):
    def getMenuItems(self, object, request):
      items = super(FooMenu, self).getMenuItems(object, request)
      base = 'http://baz.qux.com/' # the base URL will be the absolute url for
                                   # my application root
      for item in items:
          item['action'] = '%s/%s' % (base, item['action'])
      return items

And register my foo menu like so:

  <menu
    id="foo_menu"
    title="The Main Foo Menu"
    class="fooapplication.browser.menu.FooMenu"
  />


This does work, but feels a bit icky - although I cannot really say why. Is
there a better way to achieve this?
