Re: [Zope] ZClasses & inheriting property(sheets) : yes/no?

I've been struggling with this problem myself. In particular I can't get the parent propertysheet management method to appear on the Views method list. Is it necessary that the subclass also be contained in the parent? In my design, there is no containment or acquiring relationship between the parent class and the subclass.

Why Not Zope? 'Cos I like to bitch! ;-)

I'm quite careful to write "it's not apparent to a casual observer whether DC is responsive or not," and do not claim anything about the accuracy of that perception. I've sent in a few patches through the Collector; sometimes the response is quick, sometimes it isn't, either of which can be a reasonable reaction depending on the seriousness of the bug. But it's often not apparent what's going on, at least to an outsider. The SourceForge bug tracking tools make it more apparent what's happening with a bug (or not happening); so does Bugzilla, but Bugzilla seems endlessly overcomplicated in other ways. --amk

authenticate and Zope 2.2.4
by brocken22＠gmx.de 01 Dec '00

01 Dec '00

Is it possible that since 2.2.4 the authenticate-method is no longer allowed?? In an 2.2.0-installation a script to authenticate users it's working perfectly and in two other machines(win98 and Linux) with 2.2.4, Zope doesn't want the user(role as manager) to use it(a pop-up-authentication-window appears). Why??And if authenticate it's no longer allowed(the reasons?), which method can you use to check the correctness of a password?? Thanks Sven -- Sent through GMX FreeMail - http://www.gmx.net

trouble: products created inside Zope, updating from 2.1 to 2.2
by Thies Bähr 01 Dec '00

01 Dec '00

Hi, there are two types of Zope products: Products created via the Zope Web-Interface and products defined as python classes which are then icluded through a product directory. Unfortunately, the only information I discovered so far deals with these external products. As I understand it, the security model changed from version 2.1 to 2.2. Some HowTos describe the necessary actions to polish up older external products to run them in 2.2 and above. My problem is, that the product we defined via the Web-mechanism inside an older version of zope gets authorization failures. I have absoluteley no idea, where to adjust the security. I tried to create a new product in Zope 2.2.2 and to copy the content from the old to the new one but nothing changed. Being one of the few zope users who wants to use Zope without being a python programmer, I'm a bit lost now.

Factoids for supporting zope
by albert boulanger 01 Dec '00

01 Dec '00

I am going through a justification (risks) of the use of Zope for a corporate client. Framing things as an Open Source play relies on the health of its community for its longevity and access to expertise for support. I remember some number tossed out when the Members folder at zope.org went to Btree. What is the current # of Members? Is this an estimate of the Zope community? I think there is probably some dead wood in that # but at least its an estimate. I remember it being over 10K. Our client thought that the recent VC money was about 1/2 what would be needed to make it fly. My argument is that money is leveraged by the active Zope community so a crux in my logic is how strong this community is. Other support? Regards, Albert Boulanger aboulanger(a)vpatch.com

getattr in Python Method problem
by Peter Bengtsson 01 Dec '00

01 Dec '00

In the folder where dosomething_pym (Python Method) is located, is also a string property set called 'en' with the value 'English' The Python Method object is called with no parameters, but is defined with the 'self' parameter inside the Python Method object. In a DTML Method this works fine: <dtml-var "_.getitem('en')"> and returns "English" This is what I try in the Python Method: lang=getattr(self,'en') but this raises an error! Error Type: AttributeError Error Value: validate I have searched the mailing list but in vain. Some people say it should be lang=getattr(self,'en')(self,REQUEST) But that raises the same error. Best regards, Peter

Accessing methods in Python Objects
by Cyril 01 Dec '00

01 Dec '00

Hi Zopistas, My first message :-) How can access Python objects' methods from a DTML Method. I get An 'Unauthorized' exception. I would like to do the following: <dtml-let myObj="newObj()"> <dtml-var "myObj.sayHello()"> <dtml-call "myObj.setValue('Bonjour')"> etc... </dtml-let> where 'newObj()' is defined in an Extensions module as: import someObject # a module defining the someObject class def newObj(): return someObject.Object() Actually I must wrap methods in my extension module, not very clean :-/ Is it possible to create roles and permissions in Extensions modules ? And if yes, is a good fellow ready to explain how :-) Thanks in advance, Cyril Elkaim
