[z3-five] Using templates for content providers

[Anton Stonor]

How do I use a page template to render a content provider on Zope 
2.9.3/Five 1.4?

My dummy content provider works (see below).

Now I want to use a page template to render the HTML fragment.

However, doing this ....

render = ZopeTwoPageTemplateFile('fragment.pt')

.... gives an error:

Traceback (innermost last):
   Module ZPublisher.Publish, line 115, in publish
   Module ZPublisher.mapply, line 88, in mapply
   Module ZPublisher.Publish, line 41, in call_object
   Module Products.five_hello_rdb.rdbview, line 41, in __call__
   Module Shared.DC.Scripts.Bindings, line 312, in __call__
   Module Shared.DC.Scripts.Bindings, line 347, in _bindAndExec
   Module Shared.DC.Scripts.Bindings, line 1, in ?
   Module Shared.DC.Scripts.Bindings, line 292, in _getTraverseSubpath
AttributeError: 'str' object has no attribute 'other'

It seems like the REQUEST attribute on the ZopeTwoPageTemplateFile 
instance is a string-like ('<Special Object Used to Force Acquisition>') 
where _getTraverseSubpath expects a request object.

Any ideas?

Another, related issue: Is it possible in ZCML to configure a page 
template to be used for a content provider - like for normal views?


class StupidProfider(object):
     zope.interface.implements(interfaces.IContentProvider)
     zope.component.adapts(zope.interface.Interface,
                             browser.IDefaultBrowserLayer,
                             zope.interface.Interface)

     def __init__(self, context, request, view):
         self.__parent__ = view
         self.request = request
         self.context = context

     def update(self):
         pass

     def render(self):
         return "hello world"
