zope changes : dtml-var
by Martin Krallinger 16 Feb '10

16 Feb '10

Hi, it seems that there some of the options in zope had been changed. I have been looking in the documentation but did not find any explanation on what I am trying to do, which results in a formatting error message in new zope version, but worked fine in the older one. I have an input form, to which I provided a dtml-var as value,something like: <td> <input name="_valuename" size="20" value="<dtml-var person_name>"> </td> How can I provide as value now the variable <dtml-var person_name> ? It seems that there are substantial changes here.

Maintain Last Modified during Copy
by Brian Brinegar 12 Feb '10

12 Feb '10

I'm looking for a way to copy content from one database to another without updating modification times. I believe the modification times are tied to transaction IDs which may mean this isn't possible. Moving objects does not update their modification times, but, it doesn't seem to be possible to move objects from one storage to another. One option that works is to copy the entire database, remove everything I don't want, and then pack it. But this isn't ideal. Any suggestions? -- Brian Brinegar Web Services Coordinator Engineering Computer Network Purdue University

Hi, Any pointers to restart Zope 2 (ZServer) gracefully ? Does "Lifetime.shutdown(1)" will do that ? Regards, Baiju M

FYI: silent fail in ancient zope (2.10.3)
by knitti 03 Feb '10

03 Feb '10

Hi, I didn't find a bug on launchpad (didn't search _very_ hard), but I also don't have a recent zope at hand to verify this problem is still there. That's also the reason I didn't consider filing a bug. Zope Version (Zope 2.10.3-final, python 2.4.4, openbsd4) Python Version 2.4.4 (#1, Aug 15 2007, 13:27:05) [GCC 3.3.5 (propolice) When instantiating a BrowserView (perhaps also elsewhere) if I refer to an inexistant key on request, creation of the view fails silently; the user gets a NotFound, which is ignored by default. sample code (test.py): from zope.app.publisher.browser import BrowserView #from Products.Five.browser import BrowserView # no difference class A(BrowserView): def __init__(self, context, request): self.request = request self.context = context dummy = self.request.garbage def __call__(self): return 'Foo' configure.zcml: <browser:page for="*" class=".test.A" permission="zope2.View" name="a" /> error: Traceback (innermost last): Module ZPublisher.Publish, line 110, in publish Module ZPublisher.BaseRequest, line 498, in traverse Module ZPublisher.HTTPResponse, line 671, in debugError NotFound: <h2>Site Error</h2> <p>An error was encountered while publishing this resource. </p> <p><strong>Debugging Notice</strong></p> Zope has encountered a problem publishing your object.<p> Cannot locate object at: http://127.0.0.1:8087/a</p> I searched almost a day for a silly typo :-) regards, knitti

Save references in a list as object attribut
by Vladislav Vorobiev 29 Jan '10

29 Jan '10

Hello, I try to save references to objects as attribute in a list. object.refList=getattr([self. context.pfad, 'object'], [self.context.pfad, 'object1']) After adding and transaction commit I can get my linked objects with all attributes and methods myObject.refList [<myType at object>] myObject.refList[0].objectValues()[0].getPhysicalPath() ('', 'path', 'object') myObject.refList[0].objectValues()[0].absolute_url() http://localhost/pfad/object I restart the instance and get some other results myObject.refList [<myType at object>] myObject.refList[0].objectValues()[0].getPhysicalPath() ('object',) myObject.refList[0].objectValues()[0].absolute_url() 'object' It seems that the in list referenced object ist no more in context after restart. the constructor for this looks like: object = myObject() id=myObject myObject.id = id myObject.title= id myObject.refList=getattr([self.context.pfad, 'object'], [self.context.pfad, 'object1']) self.context._setObject(id, ob) The references without list object.ref=objectreference working after restart. Similar conducts Set und PersistentList. Whats the problem anybody an idea? Can anybody reproduce the problem? Zope2.12, python2.6 -- Best Regards Vlad Vorobiev

using formlib for nonclasic content types
by Roberto Allende 28 Jan '10

28 Jan '10

Hello Following example 18.3.1 and 18.3.2 from phillkon's book, i'm trying to define a MySite class in Zope 2.12, which look like this: class IMySite(IPossibleSite, IContainer): """ """ id = ASCIILine( ... name = TextLine( ... class MySite(SiteManagerContainer, BTreeContainer): implements(IMySite) So far so good, i've an interface and a class extending SiteManagerContainer and BTreeContainer. Problem becomes when i want to define the add form. If i'm not wrong, I cannot use the same machinery as zope3, so i was trying to use formlib: class MySiteAddForm(AddForm): form_fields=form.Fields(IListo) And i doesn't work. The error i'm getting is: NotImplementedError: concrete classes must implement create() or createAndAdd() I was looking info about them but i wonder i'm running with a conceptual gap here, because this is the same problem i had to define MySite inheriting from Folder. The same problem happened there, i was able to define the class but when i needed the form i wasn't able to use formlib and i used old-zope2-like-code. Probably i could try to do smt like that, but i'm very curious to see how can i use formlib in such cases. The question then is, is it possible or would it make sense to do something like this ?. Do you know about a sample code that could be helpful ?. Any comment or hint would be very appreciated. Kind Regards r. -- http://robertoallende.com

Re: [Zope] Safe way to abort or re-start stalled out ZODB pack?

Thanks Bakhtiar, That's what I was hoping, and I wanted some confirmation from those who've done it. I just did as you indicated - deleted Data.fs.pack, then ran the pack again. It completed successfully. regards, John S.
