Aiieee! 2365 exited with error code: 25
by Josef Meile 23 Dec '02

23 Dec '02

Hi, I was having this error message and found that it's caused by a 2Gb-storage-limit that zope has. I had to delete some data to reduce the size of my ZopeDB. Now it works. I have the following questions regarding this problem: 1) Does the current zope stable version (2.6.0) have the same problem? 2) Is there any patch to solve it in Zope 2.5.1 and later? 3) If the answer to the first question is "yes", what is the easiest alternative to store this data externally: LocalFS or relational databases? Are there other alternatives? Which one does zope.org use? Is it easy to convine this alternatives with the portal_catalog that it's included with CMF. Thanks in advanced and merry xmas to everybody, Josef.

ZPT RestrictedTraverse Bug??! ref: priveleges problem???
by Dirk Collins 23 Dec '02

23 Dec '02

I have been setting my new Zope site to allow anonymous visitors to burrow down till they hit a restricted area, namely the 30mm CD Resources page. Right above that is the 30mm-Floorplans folder. Anonymous users are being required by zope to login at the 30mm-Floorplans folder even though I didn't specifically setup the 30mm-Floorplans folder as a controlled area. Canceling the login request results in this Zope error for anonymous users only! /<li> Module Products.PageTemplates.Expressions, line 346, in restrictedTraverse<br /> __traceback_info__: {'path': ['title'], 'TraversalRequestNameStack': []}</li> </ul>Unauthorized: You are not allowed to access title in this context </p> -->/ Everyone else can gain access to the 30mm-Floorplans Folder so long as they login. After spending some time making sure the folder and file permissions were good from the Zope root folder on down to the 30mm-Floorplan folder, I finally got the bright idea to check Google using the keywords in the error message and found my problem straight away... Reference URL-- http://lists.zope.org/pipermail/zope-coders/2002-September/002080.html I'm just checking to see if anyone happens to have any updated information on this bug, or if a workaround already exists to allow anonymous users access to all the areas that role is setup for. With Regards, Dirk

The "undo" posibility and the size of data.fs
by borge＠tsar.no 23 Dec '02

23 Dec '02

Hei we have with zope developed a multiple choice test which employees can access over the internet. This works fine. However, each time an employee submits an answer, the size of the file data.fs increases much more than we would expect(3kB). The answer is stored on the emlpoyee object. We now do wonder if zope's "undo" possibility is an explanation to this large increase in data.fs; this since zope holds the states inbetween the transactions (four transactions for each question).If it is this undo possibility that causes the large increase in data.fs, we would like to know if it is possible to get around this "undo" tracking af zope. If it is not, we would also very much like to know how we could find out what other reason there is to the large increase in data.fs. I have exported the employee object to xml to see what is there stored, but all there looks normal. Best wishes and kind regards from Børge Kjeldstad

A Zope transglobal Christmas experience
by Jan Smith 23 Dec '02

23 Dec '02

Hi All Over the past few weeks a Silva/Zope Christmas website has been built around the clock and around the globe with author Ian Keldoulis in New York, Kit Blake of Infrae in Rotterdam, and myself the Zope Template Designer in Melbourne. Due to time differences work was done while we each slept on our respective continents. It meant waking up to find an inbox with questions answered or new things added to the site. Building this site was great fun. Thanks to ZPT's a Silva website can have any look required. It's beneath the hood where Silva works its magic. WHAT IS SILVA? More information and free download from: http://www.infrae.com/products/silva Author Ian Keldoulis wanted to have a web site where he could add additional episodes without fussing with html. Ian writes, researches and edits at the New York Times, and has been involved in new media projects for many years. This Christmas site is aimed at people who want a few minutes escapism. Check out Santa's misadventures on Wall St at http://www.toyzondemand.com/ cheers Jan Smith

RE: [Zope] Accessing DOM nodes from python: how?
by Passin, Tom 22 Dec '02

22 Dec '02

[ Catonano] > I saw a javascript accessing a value put in a html tag like this: > > > <TD ID= "blah"> > Td contents > </TD> > > or something similar. > > Javavascript could read that "blah" > > Now, how can I do the same from python? Can I? > I am not at all sure what you want to do. When the javascript script accesses that value, it is operating in the browser. Python will be in the server. Why should it access the page at all? If there is data to be sent to Python, just send it the data. The page, in fact, will not actually exist for Python to "access". Only after your python scripts are done will the page be fully assembled. If you mean that you want to write some python code that you feed an html page to, that is not how you would normally use Zope. If you want Python to access a web page and retrieve some data from it while it is processing a REQUEST, that is best done using an external method. There are a variety of ways to process a web page, but it is not always easy, given the amazing range of invalid html code that exists out there. Sometimes it is easiest to use regular expressions, and sometimes it is easiest to use the sgmlop parser (you have to write a handler, but that is not too hard depending on what you need to do). Or you can turn the html page into xml using HTML Tidy, then use xml processing on the page. If you do this and use the PyXML beta (or maybe it is still alpha) package, you can get access to the W3C DOM API, and access the page element content that way. Cheers, Tom P

Content mgt for non-technical people
by Robert Wielinga 22 Dec '02

22 Dec '02

Hello, I am very new to Zope, but am impressed about the way it enables you to formalise site logic and the look and feel. However in the short time I've been using Zope, it does not seem to be a very suitable environment for non-technical people to add content to the site. Preferably, I would like people to be able to create new or modify existing content items, possibly with some workflow, without them having the need to edit html/dtml documents. For example, a content editor is presented with a form for each content type, where he can enter the relevant data in plain text and when the form is submitted, the data is entered as Zope objects in the zope server. Did I overlook some features in Zope or are there readily available modules that accomplish this? Do I have to build it myself? Regards, Robert
