[Zope3-Users] Using IPathAdapter on menuItem

[Florian Lindner]

Hey,
a IMO good solution just came into my mind while taking a nap. I implemented 
the solution in 5 minutes and it workes.
It registered a view:

    <page
        name="toHomeFolder"
        for="*"
        permission="zope.Public"
        class=".views.toHomeFolder"
        layer="centershock"
        menu="CSnavMenu"
        title="home folder" />

and the view class:

class toHomeFolder(object):
    """ Makes a redirect to the homefolder of the principal. """
    def __call__(self):
        from zope.app.zapi import absoluteURL, getUtility
        from CS.Homefolder.interfaces import ICSHomeFolderManager
        hfm = getUtility(ICSHomeFolderManager)
        req = self.request
        URL = absoluteURL(hfm.getHomeFolder(req.principal.id), req)
        req.response.redirect(URL)


Works perfect. :-)
