zpt nesting/inheritence in views
by Chris Withers 18 Apr '09

18 Apr '09

Hey All, Thought I'd share this and see if anyone had any better ideas... So, I have a set of views that subclass each other, nothing out of the ordinary there. However, I also want the zpts used by the views to "subclass" each other, such that a subclassing view can use its parent's macro(s) and provide the same to be used further downstream. This is the only solution I can think of: from Products.Five.browser import BrowserView from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile class Base1(BrowserView): template = ViewPageTemplateFile('html/template1.html') class Base2(Base1): template = ViewPageTemplateFile('html/template2.html') parent = Base1 class Base3(Base2): template = ViewPageTemplateFile('html/template3.html') parent = Base2 class Concrete(Base3): def __call__(self): return self.template(self) template1.html: <metal:x define-macro="main"> Template1 <metal:x define-slot="slot"/> </metal:x> template2.html: <tal:x define="parent nocall:view"> <metal:x define-macro="main" tal:define="parent nocall:parent/parent"> <metal:x use-macro="parent/template/macros/main"> <metal:x fill-slot="slot"> Template2 <metal:x define-slot="slot"/> </metal:x> </metal:x> </metal:x> </tal:x> template3.html: <tal:x define="parent nocall:view"> <tal:x define="parent nocall:parent/parent"> <metal:x use-macro="parent/template/macros/main"> <metal:x fill-slot="slot"> Template3 </metal:x> </metal:x> </tal:x> </tal:x> Can anyone think of a nicer way that doesn't involve the 'parent' attribute on the view classes and has (preferably much) nicer code in the zpts? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

z3c.javascript license question
by Martijn Faassen 17 Apr '09

17 Apr '09

Hi there, On svn.zope.org we have a library called z3c.javascript. Never got released to pypi, but it did get released to download.zope.org/distribution It basically contains a pile of javascript libraries. These have very non-ZPL licenses. I wonder whether anyone at zope corporation ever got permission for checking these in? What shall we do with this stuff? I'm tempted to remove it wholesale, except z3c.widget uses bits in it, and that in turn is used by megrok.form, which is how all this came to light. z3c.widget is released on pypi (though newer releases exist in download.zope.org/distribution again). Wwe will probably be able to rewrite megrok.form to lose the z3c.widget dependency easily enough, so I'm going to propose we do this on grok-dev. Regards, Martijn

Zope 2.12: versions thingy in Control_Panel
by Chris Withers 16 Apr '09

16 Apr '09

Hi All, A little gotcha in 2.12 is that, because Versions are now gone, you get some weird errors when you try and view the ZMI using an older Data.fs. The following fixed it for me: >>> cp = app.Control_Panel >>> cp._objects = tuple([i for i in app._objects if i['id']!='Versions']) >>> import transaction >>> transaction.get().commit() Hope this helps!

iterating over class without __iter__ but with __getitem__ raises AttributeError:__iter__
by Chris Withers 15 Apr '09

15 Apr '09

Hi All, The context for this is trying to get ParsedXML 1.5 running on Zope 2.12 under Python 2.5 (don't ask why!) Anyway, ParsedXML has a class: class ManageableNodeList(ManageableWrapper, DOMProxy.NodeListProxy, Acquisition.Implicit): "A wrapper around a DOM NodeList." meta_type = "Manageable NodeList" # redefine to get back the [] syntax with acquisition, eh? def __getslice__(self, i, j): return self.wrapNodeList(self._node.__getslice__(i,j)) # redefine to get back the [] syntax with acquisition, eh? def __getitem__(self, i): return self.wrapDOMObj(self._node.__getitem__(i)) If you try and iterate over an instance of this class, you get an AttributeError: __iter__. This doesn't make a lot of sense, since you *don't* get an error like that if you iterate over an instance of: class X: def __getitem__(self,i): return 1 I'm wondering there's some ExtensionClass or similar weirdness happening here? (It didn't used to happen under Zope 2.9/Python 2.4) cheers, Chris PS: I have a f'ing horrible workaround for how: ... def __iter__(self): return SillyIterator(self) class SillyIterator: def __init__(self,mnl): self.mnl = mnl self.i = 0 def next(self): try: e = self.mnl[self.i] except IndexError: raise StopIteration self.i+=1 return e -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
