RuntimeError: Shouldn't load state for '\x00\x00\x00\x00\x00\x006\xd1' when the connection is closed
by Thierry Florac 30 Jan '03

Hi, I have to face a recent problem : when I restart my Zope server, I can see pages several times but after a few requests, I receive the message written in this message's subject. Of course, I'm writing my own Zope products, but never close database connection manually. Loading the given object from a little Python script (Zope.app()._p_jar['...']) gives me an "<extension class BTrees.Length.Length at 553020>". Where could this problem come from ??? I didn't make any big update on my Zope site/products before this problem occurs... Thanks for any help, Thierry -- Linux every day, keeps Dr Watson away... http://gpc.sourceforge.net -- http://www.ulthar.net

Iterate over Z-SQL objects

Hi, For reference, I want to produce a list of all of my Z-SQL objects, showing the ID and SQL-Template of each object. Is there an easy way of doing this ? There's no reference in the docs to any method which can pull out the SQL-Template text from a Z-SQL object...

RE: [Zope] New Management Tabs and data types only with ZClasses or products
by hohage 30 Jan '03

Thanks for your advice. I'd like to make a more obvious description. One of the goals is to build a news site. Should I prefer to save the news articles as properties of the news folder or as separate documents inside the folder. I've read about issues concerning very large folders. Not by size, but by amount of objects. Isn't btreefolder therefore being developed. If I choose to go the way of independent objects in 2 years I' ll have >3000 objects in the folder. Otherwise >6000 properties of one folder object.

Re: [Zope] WYSIWYG Editor for Zope.

While it is indeed a better idea to have users edit content and not markup, if you do insist on it you will have a much easier time with Page Templates. Page Templates were designed (among other reasons) to deal with the very problem you describe below: many (most?) HTML editors have issues with the dtml tags, since, in general, they think they know better than the source they are given. That's generally not a problem with attributes to standard tags (as in PTs) since most editors will realize that there can exist attributes they will know nothing about. Another neat thing about PTs is that so long as the macro attibutes remain in place, you can present whole-seeming pages to your users, and they can change the page at will without damage to the surrounding structure of your finally-rendered page. With DTML, you're often working with HTML fragments. If you're worried about difficulty, don't be. Page Templates can look a little intimidating at first (there are a bunch of seemingly-cryptic characters), but it isn't bad at all. I did DTML for a long time, but since I switched to Page Templates, I can barely think in DTML at all. As for editing, especially with PTs, you can also, say, mount Zope as a WebDAV "drive" and use whatever editor you want. Some can do WebDAV themselves (Macromedia?). The ExternalEditor product is also something to look at (even if just for administrative use.) I'd really like to see some sort of Zope tool that uses the Mozilla editor widget in-place (it might indeed exist somewhere), perhaps as part of a larger management suite. But that's a whole different kettle of fish. --jcc -----Original Message----- From: "Javier de la Torre" <javi(a)reggae-news.net> To: <zope(a)zope.org> Date: Thu, 30 Jan 2003 15:25:34 +0100 Subject: [Zope] WYSIWYG Editor for Zope. Hi. I'm new in this list and this is my first message to the community :) Well, here come my question. I've been searching around for a Wysiwyg editor that i could include to edit the content of my DTML documents. I founded some web pages (here is a list of possibilities) explaining how to integrate an IE Editor inside Zope but after the instalation of it (the one from vsbabu.org exactly because it also has the posibilities to include images and links from the server) i founded a very anoying problem. When you edit a document with this Microsoft Editing control it removes my <dtml-var standard_html_header> and starts writing after my <dtml-var standard_html_footer>. So it brokes the structure of my page. My final idea is... i've got a web page managed by non technical users. In every web page there's a link to an administration page where they will have this visual control to edit the contents of this specific page. This will make everything very easy. I can't understand why this kind of tool is not more developed for Zope when probably it will make the editing of documents no so awful for non technical persons. Thanks in advance.

A QueueCatalog question
by Chris Muldrow 30 Jan '03

30 Jan '03

QueueCatalog appears to be the greatest thing since sliced bread for delaying some catalog indexing. I do have a question about something that I couldn't really grok from the source code. What exactly am I specifying when I put a number in the "buckets" blank? It's not the number of objects to hold until indexing the fields, is it? Thanks -- Chris

New mailing list
by seb bacon 30 Jan '03

30 Jan '03

Hi and sorry for the cross-posting. Following some discussions on zope3-dev and #zope3-dev regarding migration issues, it was agreed to set up a new mailing list, for the non-technical discussion of issues relating to the changeover from Zope2 to Zope3. If you have an interest in the matter, please sign up. <http://mail.zope.org/mailman/listinfo/zope2-migration> The process of migrating from Zope 2 to Zope 3 will be more than just implementing some migration scripts. This list is intended to discuss all aspects of migration, including: * Zope 3 PR: helping people understand its implications, timings, etc * Legacy support strategies for Zope2 * Documentation of the upgrade path, and other supporting materials As a starting point, here are some links to previous threads on the matter: Release roadmap thoughts: <http://mail.zope.org/pipermail/zope3-dev/2003-January/005312.html> From the same thread, Paul's response is particularly worth reading: <http://mail.zope.org/pipermail/zope3-dev/2003-January/005314.html> Branding: <http://mail.zope.org/pipermail/zope3-dev/2003-January/005338.html> Zope3.org: <http://mail.zope.org/pipermail/zope3-dev/2003-January/004767.html> seb

Header information on file upload
by Martin Gebert 30 Jan '03

30 Jan '03

Hi! In my HowTo about dealing with BLOBs <http://www.zope.org/Members/murphy/MySQL-BLOBs> I use a rather unelegant but working method to get the content type of an uploaded file. Stefan Tjarks has now drawn my attention to the Header attributes of the uploaded form data, namely the "Content-Type" attribute which seems to reveal the MIME type (photo.headers['Content-Type'] for the given exsample). My sorrow is now that this information isn't 100 % reliable, 'cause the Zope core (esp. the Image and File classes) doesn't seem to use this possibility either, but implements it's own methods which I use in the HowTo, too. The responsible class ZPublisher.HTTPRequest.FileUpload seems only to reach through the header information from the browser. Also I've learned through SelfHTML that the MIME type support of browsers has holes sometimes, as described for the accept attribute of the <form> tag. Does anybody have further information on that issue, and why headers['Content-Type'] isn't used by Zope (it is, in fact, but in ZPublisher for seemingly other purposes)? Martin
