Editing Question
by Simon 13 May '03

13 May '03

I am just starting to play around with Zope, and one thing that I would like to do it to provide custom editing interfaces for a page. What I am thinking is (as an example) an article or paper that has say, a title, an abstract, a body and a few other components. I am thinking that DTML Documents are the way to go for these components. What I would like to do it put next to each section, an "edit" button, the onclick handler will set the content-editable proprety of the associated text block to true, and will reveal save and undo buttons. This, I have no trouble with, but what I cannot see how to do in Zope, is to have the save button post the new content to the DTML document that it belongs in. Is there a good solution to this? Thanks in advance, Simon

Newbie: creating objects programmatically
by Richard Jennings 13 May '03

13 May '03

I am building a small application based on the "Build a simple ZClass (CatalogAware, non-default Catalog, Folderish)" how-to, but entirely using ZPT - I don't want to learn dtml! The objectManager constructor works fine with the lines as follows: instance = container.Directory.createInObjectManager(request['id'], request) instance.manage_addDTMLMethod('index_html','',instance.def_index) When I try to replace the dtml with: instance.manage_addProduct['ZopePageTemplate'].manage_addZopePageTemplate('memberIndex.pt') I get:Error Type: AttributeError Error Value: ZopePageTemplate when creating an instance of the ObjectManager ZClass. I have read many of the how-tos available, including the DTML to ZPT Conversions and hacked a lot but I can't find my error. Can someone help me please? Regards

Re: Data loss after packing in Zope 2.6.1?
by Jeremy Hylton 13 May '03

13 May '03

There are several bugs in the pack implementation in Zope 2.6.1, some of which could cause data loss. I fixex these bugs a couple of weeks ago, and sent a status report to the zodb-dev mailing list. I should have reported the resolution more widely, because the possibility for data loss is of interest to wider audience than reads the developer list. The technical summary I posted on zodb-dev is here: http://mail.zope.org/pipermail/zodb-dev/2003-May/004945.html The long and short of it is that we have a better test suite that provoked the known bugs in 2.6.1 pack. And we have a new pack implementation that fixes all those bugs. I had originally planned to leave Zope 2.6.x as it is, because the changes involved in the new pack are fairly significant and we only had one or two isolated reports of problems. Since several more people have reported problems, we've decided to add the new pack implementation to the Zope 2.6 release branch. We need people to test this code! If you have had problems with pack recently, it would be really helpful if you could run the new code on your database and verify that it fixes your specific problem. Jeremy

ZPT and ZClass
by Kevin Worth 13 May '03

13 May '03

I'm trying to transition a site from DTML to ZPT. I have some ZClasses that I would like to use "as is" until I get a chance to rewrite them. When I try to display an object in a Page Template, it fails (the Zlcass instance is called "bubbles" and is a folderish object with a few properties and contains a Photo Here is what I try to make it work: <span tal:replace="structure container/bubbles"/> Result is the page is rendered with nothing where the object should be. If I view the source of the rendered page I see <highlight at bubbles> where the object (a highlight named bubbles) should be. Then I tried: <span tal:replace="structure container/bubbles/index_html"/> Result is: Error Type: NameError Error Value: global name 'caption' is not defined "Caption" is a property of the object. index_html is a DTML method Am I trying to do the impossible, or am I missing something?

how to use the document object in a script
by Wim Bekker 13 May '03

13 May '03

Wrestling with the ZopeBook (ScriptingZope.stx), I'm trying to call a script from a DTML document to return eq the title for the document (as learning curve). The document has: <form action="myScript" method="POST> <input type="submit"> </form> The 'myScript' has: Return context.title The result is the title for the folder where the document is in. I'm expecting the title for the document itself. Context always seems to be the folder I'm working on. How do I get the object (document)? Wim

(no subject)
by Anand Hattiangadi 13 May '03

I have installed Zope on a Red Hat 9 server, set ownership of everything to myself, installed CMF and CMFPlone. I can start up (running as myself), and initially everything seems to be running fine. However, after clicking around a few spots on the /manage page or a test plone site everything grinds to a halt. The Z2.log shows no more requests, stupid.log (Error severity level = 0) shows no further entries besides the usual startup INFO(0) entries, the server doesn't respond any more. The only thing to do is to stop and start (from command line, killing process), and if that doesn't work I manually delete the temp files/lock files from the /opt/zope/var, and that does the trick. I installed basically the same deal on RH 8 on a different machine and it worked like a charm. Do you know of any incompatibilities with RH9? Do the downloaded binaries not work? Or is it some other problem entirely? Thanks in advance for your help, Anand -- Anand Hattiangadi <anand.hattiangadi(a)sun.com>
