If Jelle Gerbrandy is using Win98/Access there must be a reason (I cannot think of any good one :) ) Maybe just changing Access to MySQL or Interbase (Interbase runs under Win98, MySQL I´m not sure, I think it does) would be a middle term as changing OS is a bigger move (I would change as in my opinnion Win98 is NOT an end user OS not a developer one) Jacques

DTML problem
by Wolfgang Klinger 26 Jul '00

26 Jul '00

Hi! ---------------------------- I use the following expression in a header file which is included in every document/method to get the content of the actual folder and show the title as menue item. <dtml-in expr="PARENTS[0].objectValues(['DTML Document'])" sort=title> <tr> <td><a href="<dtml-var "absolute_url()">"><dtml-var title></a></td> </tr> </dtml-in> But I don't want to show the current "DTML Document" as part of the menue. ---------------------------- example: Communication (Folder) | | |- <default_html_header> (DTML Method) | |- Contact (Folder) | | | |- <index_html> (DTML Document)> | |- <contact_addForm> (DTML Document)> | |- .... | |- News (Folder) . | . |- <index_html> (DTML Document)> |- .... ok, <default_html_header> uses the dtml expression above and is included in every other document/method/whatever ... <contact_addForm> includes <default_html_header> and I don't want to show <contact_addForm> in the menue!!!! How can I exclude the current document? TIA Wolfgang

Lines data type possible in boolean OR's?
by Alexander Limi 26 Jul '00

26 Jul '00

Hi, I have a small problem. When I use the lines data type in OR statements, I get an Error Type: TypeError Error Value: bad operand type(s) for | I've used them earlier on integers, like this: <dtml-if "cabinDouble | cabinTwin | cabinBunk | cabinPullman"> and it works fine. When I try the same with other data types, like this: <dtml-if "toy | additionalToys"> where "toy" is a "multiple select" type and "additionalToys" is a "lines" type. Can anyone provide me with some hints on what to do to get it working the way I want? Is typecasting necessary? Thanks in advance. Alexander. PS: please CC me if you answer :)

problem with manage_permission
by Jerome Alet 26 Jul '00

26 Jul '00

Hi, I'm currently trying to create a python product. I've got a class named MyClass, and in the __init__ method I've got the following code: self.manage_addFolder(id="data", title="MyClass instance's datas") self._addRole('admin') self.manage_permission(permission_to_manage = "Access contents information" , roles = [ 'Manager', 'admin' ]) MyClass inherits from Folder. I want to programmatically create a 'data' Folder and an 'admin' role in each new instance of MyClass, and give this role and Manager (but not Anonymous) the "Access contents information" permission. The manage_addFolder and _addRole work fine, but the manage_permission call gives me the following traceback: Error Type: AttributeError Error Value: aq_acquire Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addMyClass) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_addMyClass) File /usr/local/zope/lib/python/Products/MyClass/MyClass.py, line 45, in manage_addMyClass File /usr/local/zope/lib/python/Products/MyClass/MyClass.py, line 153, in __init__ (Object: ElementWithAttributes) File /usr/local/zope/lib/python/AccessControl/Role.py, line 208, in manage_permission (Object: ElementWithAttributes) File /usr/local/zope/lib/python/AccessControl/Role.py, line 136, in ac_inherited_permissions (Object: ElementWithAttributes) File /usr/local/zope/lib/python/OFS/ObjectManager.py, line 173, in _subobject_permissions (Object: ElementWithAttributes) AttributeError: (see above) Surprisingly, if I delete the manage_permission line, restart Zope, re-add an instance of MyClass (it works), then try to manually modify the permissions using the MyClass instance's security tab, then it works flawlessly. Does anyone have got an idea about where the problem may come from ? thanks in advance.

re: [Zope] Zope performance ratios
by Jarkko Veijalainen 26 Jul '00

26 Jul '00

I'm doing a performance comparance between Zserver and Iplanet servers packages in next couple of weeks, maybe with Apache and Netscape servers too. We have building a prototype with four different sripting languages, including Zope. Goal is to find out wich combination is most effective. Maybe i can post some results here, when my reasearch is done. jarkkov -----Original Message----- From: andres(a)corrada.com [mailto:andres@corrada.com] Sent: 24. heinäkuuta 2000 20:54 To: zope(a)zope.org Subject: [Zope] Zope performance ratios I'm interested in getting performance statistics for Zope. I'm scouring the mailing lists for previous messages but I would also be interested in anything else people may want to say about it. For example, what is the record for average web hits from a Zope site? Does someone have a feel for useful ratios like: "a Zope page takes, on average, twice as a static page to serve"? I'm not interested in being anal about the numbers, seat of the pants estimates are what I'm looking for. ------------------------------------------------------ Andres Corrada-Emmanuel Email: andres(a)corrada.com ------------------------------------------------------

Updating product property sheet values
by Paul Smith 26 Jul '00

26 Jul '00

Hi I have just been asked to stop banging my head against the wall, as it is annoying other people in the office, so I turn to you all in the hope you can help! I am trying to create a moderated news bulletin board, and have based the back-end loosely on the Job Board engine, as "Created by mukhsein" and available as a How to on Zope.org. So far, I have successfully implemented the posting of news items, and have assigned them a property sheet value which means that I can display items which I have manually created with a 'live' value. The property sheet has 3 properties, news_title, news_content and live - live being a flag indicating whether the news item has been moderated. Default is '1' for unmoderated. I have also created an 'update form' which displays all the news items which are ready to be moderated ('live' value of 1). What I am failing miserably to do, is update the property sheet value, so that the news items are displayed in the 'live' list, rather than the to-be-moderated list. I want to be able to do this by submitting the moderated news item, and changing the value "live" from a '1' to a '0'. I am attempting to do this by sending a value as a hidden value within a form when the news item is submitted. I know that I am being pretty vague in this summation, but am interested to know if anyone can point me in the right direction - if you require code samples, I can provide, but really the base code is pretty similar to that of the Job Board (http://www.zope.org/Members/mukhsein/job_board_howto) without the search element. Any guidance will be greatly appreciated.

Re: Problem

Anvita, JavaScript is inlined in a DTML method just like it would be inside a file on a filesystem. Because JavaScript runs on the client, you just need to make sure that you return it somehow in the response to the client. There is no "magic" to doing this... as a simple example: - create a DTML method with the following body: <HTML> <HEAD> <TITLE>Test</TITLE> </HEAD> <BODY> <script> alert('hi') </script> </HTML> - view it You should see a JavaScript alert box in your browser. ----- Dear Sir, Thanx for promt reply. I could get some help but still unable to find some material abt "how to call JavaScript while creating our site using Zope". I tried but couldn't succeed. I would be thankful if you'll tell me something about it too. Thanking you, Yours truly, Anvita Bajpai Research Engineer IIT Kanpur - India.

Hello! http://www.zope.org/Members/phd/mod_pcgi2/mod_pcgi2_v1.1.2_stable/ mod_pcgi2 version version 1.1.2 announced stable! The module works perfectly whether installed on root location, on non-root location or on longer location. Editors successfully manage the site, visitors happily view it, no problem with Apache/Zope have been reported for a long while. The site started on Zope 2.1.4, later upgarded to Zope 2.2.0b2, b3, b4; now it runs on Zope 2.2.0. Both ZServer and PCGI-only modes work fine with mod_pcgi2.

Vincent, This may be helpful: http://www.zope.org/Documentation/Guides/ZSQL-HTML/ZSQL.1.1.4.html Also, this question is more suited for the main Zope mail list (zope(a)zope.org) I've moved it there as a result.

Problem with ZCatalog output and SiteAccess (with workaround)
by Marcin Kasperski 26 Jul '00

26 Jul '00

In short: ZCatalog getpath method returns sth. like '/public/the/path/to/found/object' It causes the problem when one uses SiteAccess to modify URL paths (let's say I use Apache mod_proxy to redirect http://my.host/zope to http://my.host:8080/public and set SiteAccess in public zope dir to return http://my.host/zope) URL's generated from ZCatalog searches via 'tutorial way': <a href="<dtml-var "catalog.getpath(data_record_id_)">"> does not work. I get sth like http://my.host/public/the/path/to/found/object (and Apache claims no /public directory on server). The problem can be solved via via converting fully specified link returned by getpath to relative link (in most cases it is enough to split this string on slash, remove 2 leading items and join it again) - then I get correct URL without SiteAccess intervention. Code snippet from zcatalog search result form: <dtml-comment> This does not work with SiteAccess/proxying <a href="<dtml-var "catalog.getpath(data_record_id_)">"> </dtml-comment> <dtml-let page_path="catalog.getpath(data_record_id_)" page_split="_.string.split(page_path,'/')" final_path="_.string.join(page_split[2:],'/')" > <a href="<dtml-var "final_path">"> </dtml-let> <dtml-var title></a> This is rather workaround than clean solution. I can imagine two 'true' solutions: - patching ZCatalog to return relative URLs only - patching SiteAccess to do something with '/such/urls' (is it possible?) -- Marcin.Kasperski | You have the right to change your mind, to substitute @softax.com.pl | functionality, and to change priorities.
