Hi!I've encountered a problem when trying to render views (there is no problem with rendering pages), but for instance with the '+' view that is defined in app/container/browser/configure.zcml <view for="zope.app.container.interfaces.IContentContainer" name="+" menu="zmi_actions" title="Add" class="zope.app.container.browser.adding.ContentAdding" permission="zope.ManageContent" allowed_attributes="addingInfo isSingleMenuItem hasCustomAddView"> <page name="index.html" template="add.pt" /> <page name="action.html" attribute="action" /> </view> when called with: markup = view() ['view' being the 'view' variable gotten from ZPT) results in the following error message: ... markup = view() File "/home/jmo/Zope3/src/zope/app/publisher/browser/viewmeta.py", line 445, in __call__ attr = self.__page_attribute__ AttributeError: '+' object has no attribute '__page_attribute__' because the __call__ method of zope.app.publisher.browser.viewmeta.simple expects views and pages to have a page attribute: def __call__(self, *a, **k): # If a class doesn't provide it's own call, then get the attribute # given by the browser default. attr = self.__page_attribute__ With the '+' view described above, there is a default page attribute to use for displaying the view ('index.html') and but no page attribute explicitly assigned. The following patch fixes the problem, but I'm afraid that I'm missing something: are views supposed to have a '__page_attribute__' or not?
They are only supposed to ave a page attribute if they are pages. :) The directive above creates a view *with pages*. This means that the view itself should not a page and is not intended to be callable. Bottom line: views created this way are not callable and are not directly renderable. There's a bit more complexity than I'd like in these view directives. This is why, more and more, I tend to *define* views in Python and just register them with the adapter or view directive. I still do often find it useful to register views with the view directive, mainly so I can avoid having to mention IBrowserRequest. Jim -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!
