dtml-with in python script
by Chris Kratz 21 Jun '01

21 Jun '01

Hello all, Folder structure is like this root |-SharedCode | |- CodeSnippet |-Folder a |-Folder 1 |-Folder A I put pieces of code we use across the whole website in Shared code. If I want to get CodeSnippet I use the following code in DTML. <dtml-with SharedCode> <dtml-var CodeSnippet> </dtml-with> Now, how do I do this in a python script? There doesn't seem to be an equivalent command like dtml-with to push a folder onto the namespace. And getitem doesn't support getting objects that are not in the namespace. Help!! Things I have tried (among many) _['SharedCode']['CodeSnippet'] - Returns Code Snippet, but all " are returned as ", I need " _.getitem('CodeSnippet',1) - Doesn't work, not in namespace. _.getitem(_['SharedCode']['CodeSnippet'], 1) - Doesn't work _['SharedCode'].getitem(... doesn't work because getitem is associated with the _ namespace. etc, etc, etc -Chris

multiple selection with methods
by Dominique Jouniot 21 Jun '01

21 Jun '01

Hello all, Itseems really difficult to have some informations about multiple selection (i send a message and see an other one without response). Then i ask again: how could we insert a method (pyhton perl or DTML) from a particular place (but not directly placed in the Zclass definition, and with argument in an attribut definition (in a Zclass Object). The goal is, when we instanciate the object (in zope), the creator of the instance of the object could initialize the attribut we informations taken from a list. I need the syntax and the limit of possibility !! Thanks for your help Best regards Dominique Jouniot

News product + workflow
by Timothy Wilson 21 Jun '01

21 Jun '01

Hi everyone, I'm trying to redesign some very simple news products I've developed for use on my site. I'm going to call the new product SimpleNews and it will likely contain two parts--a basic ZClass for a short list of announcements of the type that my school broadcasts over the public address system twice a day and a ZClass for longer reports of single events like concert reviews, a story about one of our sports team's games, a letter from the principal, etc. My site is organized with the school district in the root of my zope and subfolders for each school. I've created a number of users in subfolders that are responsible for various portions of the site. No problem there. I'd like to implement some sort of simple workflow whereby my regular users would be able to publish announcements or news articles and have them immediately visible to site visitors. I also want to allow others to be able to submit news items for possible publication pending review by an official reviewer. Here are a few questions that I've come across: 1. I'd like to categorize the announcements and news by categories corresponding to the different schools, sports, arts, academics, etc. This will allow me to filter the news on a per site basis. But at the same time, I don't want someone from Spam Elementary School reviewing announcements in the Eggs Middle School category. What would be the best way to accomplish that? 2. It's unclear to me how best to implement this simple workflow. I see two possible solutions. a. Catalog each item immediately when it's submitted, but use a boolean property (e.g., "published") that would determine whether that item is visible to site visitors. The advantage of this method would be that I could construct a ZCatalog query that would pull up a list of submitted items requiring review by the site's reviewers. A disadvantage would be that I would need to construct a filter to prevent the unpublished items from appearing in every other ZCatalog query that I use on the site. Every time I used a ZCatalog query, I would need to make sure it wasn't displaying unpublished items. b. Delay cataloging until the item has been reviewed. The disadvantage of this method could be making it harder for the reviewers to process the submitted items. It may be (in fact it's likely) that there's another solution that makes much more sense. I would appreciate any feedback on this idea. Any Zope Zen masters out there have any insight on this? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.org W.

ZCatalog problems
by Jan Lentfer 21 Jun '01

21 Jun '01

Hi, I am having problems with getting back data from ZCatalog. I create instances of the ZClass "racedate". racedate has a property called "date_sort" which is the date that the race will take place in the format "yyyymmdd". In a dtml-document I read the objects with <dtml-with "admin.racedates"> <dtml-in "Catalog(sort_on='date_sort)"> <dtml-var date_sort> [...] Everything works fine until two or more objects have the same value in date_sort (eg. 20010528). Then it miserably fails. Only part of the objects or even none are displayed. I tried back and forth and it really seems to be the sort_on='date_sort'. If I do sort_on='id', all objects are displayed and <dtml-var date_sort> shows the right values. So the problem really seems to be the sorting on an index when 2 or more objects have the same value for that property. Is that a bug or a feature?

RE: [Zope] database connection

> 4) mysql 3.23.38 Unless your using the experimental transaction support in MySQL, this could be caused by Zope's ConflictError. When a conflict is detected inside the ZODB, Zope automatically retires the request up to 3 times. If you make changes to a non-transactional database, those changes will be re-run up to 3 times. -Randy

Need more enlightenment on traverse hook and security
by Dirksen 21 Jun '01

21 Jun '01

Hi, Thank you, Toby Dickenson and Dieter Maurer, for your tips on my problem. It's cracked instantly! However, as a layman of python and Zope, I couldn't figure out the meaning of "MyObj(name).__of__(self)". What is '__of__' funtion? I can dig very little information about '__of__' from python's website. What's the difference between 'Acquisition.Implicit' and 'Acquisition.Explicit'? And why these two steps are required to solve my problem? Look forward to your enlightenment. Cheers Dirksen __________________________________________________ Do You Yahoo!?

Unable to manage/edit Zope
by Mark Snellings 21 Jun '01

21 Jun '01

I have Zope installed on two development systems in my office. On the second system when I go to "manage it" http://192.168.0.1:8080/manage, I get the frame on the left frame which shows the root folder and what's in it, but the main frame just shows me the "view" of "Zope Quick Start" instead of the contents of the root folder. I am unable to "edit" it. If I attempt to manage it from another computer in the office, everything comes up fine. Also, when I use this second computer to "manage" the Zope installed on the first computer, I have the same thing. It appears to me that it related to my IE browser, but I cannot figure it out. Any ideas? Thanks Mark

RE: [Zope] CST, non-undoing Berkeley Storage, and Versions

In this case I will disable the functionality that requires sessions, if the browser has joined a version. Is the proper way to check for a Version to look for a cookie named Globals.VersionNameName ('Zope-Version')?
