Reinstall Transparent Folders (it must be in the "ZopeHome"/lib/python/Products, not in an instance) and it should be OK.

<dtml-in> tag in another <dtml-in> tag
by Leo 07 May '02

07 May '02

Hello, I have a problem to assign a variable in the dtml-in tag. If I use the following code, I can get the expected result. <dtml-in "test('/temp/1063')"> <a href="description_html?file=/temp/<dtml-in Inspector_Name><dtml-var UserID></dtml-in>/<dtml-var sequence-item>"><dtml-var sequence-item><br> </dtml-in> However, I want to get 1063 in line 1 from <dtml-in Inspector_Name><dtml-var UserID></dtml-in>, just like line 2, I failed. "Inspector_Name" is a ZSQL-method, to retrieve the UserID from the database by using the login name. "test(path)" is the external method to get the actual files name and directories name in the ext2 file system of Linux. I tried to use <dtml-in "test('/temp/<dtml-in Inspector_Name><dtml-var UserID></dtml-in>')"> instead of line 1. I failed. Please help. Thanks a lot. Leo

Caching problem
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 07 May '02

07 May '02

Hello, I have a DTML Method ... It actually outputs a .js JavaScript file ... I am trying to get the browsers to cache this JavaScript file by associating it with an HTTP Cache Manager ... But am having no success !!! The file is referred to through a <script src="" ... type link, and I know that browsers chache these because I tested it a while ago, with a .js file that was static and didn't live within Zope. Now I have a dynamic .js file within Zope and behind an HTTP Cache Manager, but Zope/Z2 insists on returning HTTP code 200 !! The funny thing is I have other objects under this cache that DO get cached. the thing is those are images ... not dynamic content. I tried switching to a RAM Cache Manager thinking if I cache the results of the DTML Method, then the browser should be able to cache it ... But no, still sending 200's ... I even tried associating the RAM cache to the HTTP cache, but that didn't work at all ... What am I missing ? How do I get these DTML Methods to cache at the browser ? these files are fairly big, so it's causing the users lots of delays ...

Tracker and Scheduled tasks
by Oliver Pabst 07 May '02

07 May '02

Hi Zope folks, as I saw in the Tracker source, it should be possible to trigger the execute_rules method to tell the Tracker to resend old Tracker issues to the supporters to alert them. Does someone know who you can trigger this with a cron job or so? -- --- --- Oliver Pabst .-------------------------. mailto:olpa@sybcom.de : : phone :+49 681 56600600 : project department : SYBCOM GmbH fax :+49 681 56600660 : : http://www.sybcom.de

Zope KeyError from nowhere
by Terry Hancock 07 May '02

07 May '02

Hi all, I ran into a major "Huh?" today in the middle of working with my development prototype in Zope. I was doing a lot of edit/test cycles in a Zope subfolder, as I have been doing for the last few months. I also periodically pack the database (though it's been a few days since I did). I don't spend a lot of time at the "Root Folder" though I generally pass through it at least once a day, and did this morning. Anyway, I happened to go back into it and got a weird error: Error Type: KeyError Error Value: Folder (traceback at end of message) (there is no object in the Root Folder named "Folder" as far as I can remember). This is displayed in the Root Folder object display window, whenever I go to the top level of the management interface. Now, this won't go away -- I tried reloading the page, restarting the Zope server from the control panel and by using start/stop scripts, etc. The fsrecover.py script says there's nothing to recover, and tranalyzer doesn't seem to show anything out of the ordinary -- the last few edits are to objects far down the tree that I was working on (and I have no trouble viewing those folders). Nevertheless the error/traceback just won't go away. Is it a bug? I'm not sure how to troubleshoot this. I guess the next step is to pick through the Zope source files mentioned in the traceback, but I thought I'd ask if anyone could recognize what happened. Any ideas much appreciated!

ObjectManager 'Contents' problem
by John Hunter 07 May '02

07 May '02

I am working on two demo classes in a Product, a Person and an Address. Both are derived from SimpleItem, and Person is also derived from ObjectManager, because I want it to be able to contain an Address in a Person. Here is my problem: When I add an Address instance to a Folder, all works as expected, so I think the Address constructor and class are ok. When I add an Address instance to an instance of my Person, zope accepts it fine (no errors) but the instance does not show up in the Contents view, which displays the message 'There are currently no items in me' where 'me' is the id of the Person instance . If I try to add another address with the same id, I get an error saying the id is already in use. But I cannot see the Address instance, even if I call a method like <dtml-in "PARENTS[0].objectValues()"> <h3><dtml-var id>:</h3> </dtml-in> on the person instance. I would appreciate any advice. I don't give a whit about persons or addresses, but plan to use this code as a template for my actual development, so I'm also happy to hear any criticism of the code below. I am using the Component/Interface design suggested in the Zope Dev Guide, and have based on lot of the code on maxm's HOWTOs and mxm classes Thanks, John Hunter ######### Person.py -- the person interface ################## from Interface import Base class Person(Base): "A person is a person, no matter how small" def getFullName(self): "Return full name" ######### PersonImplemetation.py ################## from Person import Person import Products from AccessControl import ClassSecurityInfo from Globals import DTMLFile, InitializeClass from OFS.SimpleItem import SimpleItem from OFS.PropertyManager import PropertyManager from OFS.ObjectManager import ObjectManager class PersonImplementation(SimpleItem, PropertyManager, ObjectManager): """ Person product class, implements Person interface.

alpha sorting in Metapublisher (newbie)
by Rebecca Elder 07 May '02

07 May '02

Hello all, I know this must be an easy thing but I've looked everywhere and can't find the answer so I hope you can help. I use Metapublisher to display a list of records which the user can click to go to a detail/edit page. I want to be able to display the records alphabetically by organization name. Here's my current code: <dtml-in entryIds> <tr> <td><dtml-var "mp_entries.getEntryField(_['sequence-item'], 'org')" ></td> <td><dtml-var "mp_entries.getEntryField(_['sequence-item'], 'name')" ></td> <td><a href="edit_html?key=<dtml-var sequence-item>">Edit</a></td> <td><a href="delEntry?action=<dtml-var URL url_quote>&key=<dtml-var sequence-item>">Delete</a></td> </tr></dtml-in> Much thanks in advance for any assistance, Rebecca __________________________________________________ Do You Yahoo!?

I'm using <dtml-in "_.range(31)"> to loop. What I can't seem to do is use the sequence-number to compare to anything. Is there a special wat that it needs to be reffered to? This is what I'm doing: <dtml-if "variable == sequence-number"> but it keeps error out with: *Error Type: NameError* *Error Value: global name 'sequence' is not defined* TIA Rick * * **
