I’m using Plone 4.0.5, and I’ve spent the day trying to understand plone.app.contentmenu.

I have a custom folder based archetypes type, and I’ve written a view for it. When using the default base_view (site/MyObject/base_view), everything works as expected. Using my own custom view though, the menus start disappearing, and I haven’t been able to figure it out.

First, my zcml,

<browser:page
  for="my.product.interfaces.IMyType"
  name="view"
  class="my.product.browser.mytype.MyTypeViewView"
  permission="zope.Public"
/>

The view itself is as simple as possible:

class MyTypeViewView(BrowserView):
    template = ViewPageTemplateFile("templates/mytype_view.pt")
    def __call__(self):
        return self.template()

And the view template has also been slimmed down to nothing:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"
      xmlns:tal="http://xml.zope.org/namespaces/tal"
      xmlns:metal="http://xml.zope.org/namespaces/metal"
      xmlns:i18n="http://xml.zope.org/namespaces/i18n"
      lang="en"
      metal:use-macro="context/main_template/macros/master"
      i18n:domain="plone">
<body>
<metal:content-core fill-slot="content-core">
  hi there.
</metal:content-core>
</body>
</html>

If I access site/MyObject/view, the template shows “hi there”, but plone-contentmenu-actions and plone-contentmenu-workflow disappear. plone-contentmenu-factories however, remains. if I then modify the ZCML to set name=”view_test”, and visit site/MyObject/view_test, none of the menus at all display.

I have five different views for this type, and I want the workflow menu to display on all of them (or at the very least, my main view, so that I can test more easily until I figure it out).

If I rename my view to base_view and visit the object URL directly, I still don’t have a workflow menu available.

I guess my question should be:

What exactly are the rules plone works with to decide which menus to display, and when? What code should I be reading?

— edit:

I’ve added this function to my View:

def __init__(self, context, request):
    super(MyTypeViewView, self).__init__(context, request)
    alsoProvides(self, IViewView)
    alsoProvides(self.context, IViewView)

if I place a breakpoint in my call code, I get this:

>>> IViewView.providedBy(self)
True
>>> IViewView.providedBy(self.context)
True

I’m pretty sure I only needed to apply IViewView to the view itself, but regardless, this doesn’t change anything for me.

    Since you already have a view Class (MyTypeViewView) for your page it’s more straight-forward to make it implement the interface instead of make instances of it provide it:

    from plone.app.layout.globals.interfaces import IViewView

class MyTypeViewView(BrowserView):
    interface.implements(IViewView)

    ...

    Although I think that this won’t solve your problem since I do have lots of custom views that do not implement IViewView but display all actions nicely.

    I guess you simply need to add your views to the available default views for your type in portal_types tool and you’re fine.
