Strange problem calling a base classes method
by Stefan Franke 03 Mar '99

03 Mar '99

While debugging a Product that inherits from OFS.Folder stumbled across the following problem (copied from the debugger command line stopped inside one of my Product's methods): >>> self.__class__.__bases__[0].__bases__[3].__bases__[1] <class OFS.CopySupport.CopySource at 8d11e0> >>> isinstance (self, OFS.CopySupport.CopySource) 0 >>> (self.__class__.__bases__[0].__bases__[3].__bases__[1] is OFS.CopySupport.CopySource) 1 The first line says self is an instance of OFS.CopySupport.CopySource, the second says it's not. The class objects are identical. My problem is that I'm not able to override one of OFS.CopySupport.CopySource's methods and to call the base classes method from inside. At that point I get a TypeError: unbound method must be called with class instance 1st argument which usually occurs when calling an unbound method with an instance of the wrong class. I'm clueless..

[ZDP] Announcing the Zope Documentation Project
by Martijn Faassen 03 Mar '99

03 Mar '99

Hi there, Hereby I announce in absolute adhoc anarchistic fashion the Zope Documentation Project. The Zope Documentation Project aims to generate documention on anything Zope. The Zope Documentation Project needs people who wants to help. It needs these people to get organized. To get focused, I propose the ZDP's initial project is to provide FAQs on various Zope topics. We can mine the mailing list for good questions and answers. The ZDP asks everybody to contribute. Right now we need everything. :) We need questions and answers, and we need to categorize these in separate FAQ sections. We need Zope webspace somewhere to put up the FAQ, I assume using the FAQ product. We need to develop the FAQ product further, if necessary. We need whatever you can think of. The prime mean of communications for the ZDP is the Zope mailing list, until further notice. I suggest that to keep the mailing list somewhat organized we prepend our mailing list subjects with '[ZDP]'. If somebody has a better way, we'll do it a better way. Note that while I'm sending out this message, I'm not anything official. I'm just attempting to get the ball rolling. *nudges the ball* Regards, Martijn

Bobo distribution
by Andrey V Khavryutchenko 03 Mar '99

Hi! I'm looking for Bobo (not Zope) distribution tarball. Looks like it is taken from the web away. I need to create very simple application. Zope is an overkill for it. Anyone? -- SY, Andrey V Khavryutchenko http://www.kbi.kiev.ua/~akhavr Shick's Law: There is no problem a good miracle can't solve.

Excellent! Maybe one of the Web Hosts who offer Zope hosting would be interested in the excellent public relations derived from hosting the ZDP. Phil. ------------------------------------------ Philip Aylesworth zopelist(a)regalint.com Regal International

ZPublisher and creating children
by Cees de Groot 03 Mar '99

03 Mar '99

Hi, I'm using ZPublisher+DocumentTemplate+BoboPOS in a cgi environment, because that's all I need (and can use on my ISP's box). In the couple of things I've developed so far, a pattern has emerged that disturbs me: if you have a container object, when adding a child, the whole add thing is done in the parent. IIIRC, I fetched this design from the (Bobo) Trinkets example when I started: class Container.... add = HTMLFile(....) def do_add(self, childattrone, childattrtwo, childattrthree): d = self._items d[childattrone] = Child(childattrone, childattrtwo, childattrthree) self._items = d class Child... def __init__(self, childattrone, childattrtwo, childattrthree): .... edit = HTMLFile(....) def do_edit(self, childattrone, childattrtwo, childattrthree): .... The Container, IMHO, "knows" too much about the Child in this case, and it's hard to modify the attribute set of the Child class. Am I doing something wrong? Is there a design pattern here I'm not aware of? Regards, Cees

Setting properties based on security
by Robin Dunn 03 Mar '99

03 Mar '99

I have a folder with various boolean properties associated with it which are accessed by the dtml docs as flags for enabling or disabling content. Turn off the flag and a chunk of the page goes away when it is next viewed. This works great, but I would like to associate that behaviour with the security attributes. In other words, when somebody in the Anonymous role is viewing objects in the folder the properties should be unset, but when users in the manager (or some other specific role) view the pages then the properties should be set and those parts of the pages are activated. How can this be done? -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out! Try http://AllDunn.com/laughworks/ for a good laugh.
