What is the best way to debug a Zope 2.62 application.
by Mark, Jonathan (Integic) 19 Mar '07

I have a properly running instance of Zope 2.62 but no zopectl file. What is the best way to debug this version of Zope? Should I install zopectl?

How do people work with html-designers?
by Gaute Amundsen 18 Mar '07

18 Mar '07

I have been meaning to ask this for a while.. How do people set up the zope development process and servers to work well with web-designers who use wysiwyg editors like dreamweaver? I mean, we all probably use webdav, and "external editor", but after that? After all one of the advertised advantages of ZPT, is that you can send the template back to the designer without him destroying the TAL code. (not right away at least) In practice I find that once the original html has been split into "main tempate" and "content template" parts, or the like, it gets rather impractical to involve the designer again, and we end up having the coders do way more css work than they should. I know you can leave the "dummy content" in place, but often the stylesheets, and scripts live in a different folder, and gets aquired by zope for publishing. If I could get this whole process to be more of a two way thing, I could do do stuff, like start a site with a prototype, and have the designer beautyfy that, and work iteratively, instead of allways starting with the graphic design... Perhaps it would be possible to construct a special webdav "editor view" that could "symlink" certain files into any directory, so that the wysiwyg editor finds them, or even "assemble" the templates to a page, and send the edits to the right template, or something like that. Perhaps such a product allready exists? :) Or maybe the fix is in the editor, and you can tell dreamweaver to look for stuff it can't find in the dav-filesystem, at a certain URL instead.. Anyway, I would be glad to hear how other zope-shops, deal with these kinds of issues. Regards Gaute Amundsen

Cannot Import Base has_attr...Again!

Hi; I had this problem on another server I recently built...and it went away all by itself! I'm now rebuilding my home server, and it's cropped up again. Last time, Maciej Wisniowski suggested I go to a zopectl prompt and type in "import Products.CMFPlone", but apparently that doesn't work on Zope 2.7.8/Plone 2.1.4. Here is the traceback. Please advise.

build a safe proxy
by Eric Bréhault 16 Mar '07

16 Mar '07

Hello, I am trying to build a safe proxy to wrap the Plone portal object in order to control what is allowed or not. Here is my code: class SafeProxy: def __init__(self, obj): self.__dict__['_obj'] = obj def __getattr__(self, attr): attributes_whitelist=['portal_membership', 'MailHost'] if attr in attributes_whitelist: return getattr(self._obj, attr) else: raise AttributeError, attr+" not allowed in Plomino formula context" def __setattr__(self, attr, val): raise AttributeError, attr+" not allowed in Plomino formula context" Then I use it that way: >>>safeportal=SafeProxy(portal) >>>safeportal.portal_membership <MembershipTool at /myportal/portal_membership> >>>safeportal.portal_catalog AttributeError: portal_catalog not allowed in Plomino formula context which is perfect. But my problem is: >>> safeportal._obj.portal_catalog <CatalogTool at /concerteau/portal_catalog> How can I hide completely the SafeProxy _obj ? How can I make sure it can only be used from the SafeProxy class code itself and nowhere else ? How can I turn it private ? (in Python private attributes are supposed to start with 2 underscores: __obj, but it just mangles with the classname: _SafeProxy__obj, so it just guarantees it will not be overwrite by another class, it does not physically protect it) OR (if totally impossible in Python): how can I do it another way ? maybe using zope.proxy.ProxyBase, but i do not find any documentation about it... Thanks in advance, Eric BREHAULT
