Default sort order for objects in objectManagers ??
by Max M 07 May '02

07 May '02

What decides the default sort order for the values returned when I do a "objectIds()" etc? I cannot find it on either Google or in the source. It seems that it's sorted in creation order. Is that correct and guaranteed? regards Max M

Re: [Zope] Searching Developer: Mapping WebDAV to Drive Letter

Has someone experience with webdrive vs. teamdrive on zope? Hi Thomas, I have tried the trial versions of both Webdrive and Teamdrive on a NT 4.0 SP 6 workstation. Webdrive seemed to work with no problems, but Teamdrive caused frequent bluescreens, which stopped after I deinstalled it. This probably says more about NT than Teamdrive however, as I have to reinstall NT about every 3 or 4 months to keep everthing else working. Bob Corriher P-Wave Inc.

javascript parsing error
by Mark A. Lilly 07 May '02

07 May '02

Hello, There is a line of Javascript i have which i am including in a page template (i get the same error using it via DTML) which is this: for (var y=0; y < 12; y++) <--this is correct--> for (var y=0; y < 12; y++) <--this is what the script debugger shows--> ^^^^ i get an error which says i need a parenthesis before '12'. It is saying this, i believe, because the parser is translating the '<' from the original Javascript to '<' and then the browser is not reinterpreting that as '<' The exact same code works fine when i run it straight from Apache. Something in the Zope HTMLParser seems to change the Javascript so that it doesn't work. Is there a way to leave the original code alone? Thanks, mark

Any apache Rewrite experts out there?
by Jokke Heikkilä 07 May '02

07 May '02

I just added zope to my site and have it serve all the public stuff. I want the apache still to serve all the user directories on our server, but I'm having real troubles to set up my httpd.conf to steer www.domain.com/~user to where it belongs while www.domain.com/ is taken to the zope. Currently the public www stuff resides in a folder WWW which is on the zope root. There's one VHM on the zope root also Below is the httpd.conf file as it is now, but it won't rewrite /~user requests right. Any help very much appreciated. jokke h. ---- <VirtualHost my.domain.com> ProxyPass / http://localhost:8080/VirtualHostBase/http/www.domain.com:80/VirtualHostRoot /WWW/ ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/www.domain.com:80/VirtualHostRoot /WWW/ RewriteEngine On Rewriterule /~(.+) http://users.domain.com/~$1 [R,L] RewriteRule /WWW/.* http://localhost:8080/VirtualHostBase/http/www.domain.com:80/VirtualHostRoot /WWW/ [R] RewriteRule /index.html http://localhost:8080/VirtualHostBase/http/www.domain.com:80/VirtualHostRoot /WWW/ [R] ServerName www.domain.com </VirtualHost>

How do I get rid of this message

How do I get rid of this message: .\lib\python\SearchIndex\__init__.py:19: DeprecationWarning: The usage of the Se archIndex package is deprecated since Zope 2.4. This package is only kept for backwards compatibility for a while and will go away in a future release. Please use instead the re-factored modules in Products/PluginIndexes. warnings.warn("The usage of the SearchIndex package is deprecated since \ I upgraded a server from 2.3.3 to 2.5.1, by installing a new 2.5.1 instance, and copying the Data.fs. I don't use any SearchIndex any more, all the ZCatalogs have been recreated using PluginIndexes. I have removed the references to all old products (I think). What more can I do? //Lennart

[ANSWER] 500 error with IE on login
by Gregory Dudek 07 May '02

07 May '02

This presents a longwindeded solution to a problem I posted here. I think I may not be unique in having this problem. Problem: A while back I posted a question here regarding a problem I was having with login screens. Specifically, users using MSIE on Windows were getting a "Server Error" page saying "The page cannot be displayed" (error 500) instead of my login page. The login folder product I was using was the Generic User folder product (GUF) but I am almost certain the problem afflicts other user folder products like Extensible User Folder. I am running zope 2.4 It turns out the problem is unique to MSIE (Internet Explorer) on the windows platform. As far as I know it does not occur with any other browser including mozilla, netscape (even on Windows) or even the Mac version of MSIE (Thanks due to complaw(a)hal-pc.org from this list in helping run tests). It seems to happen with version 5.5 and version 6.0 of MSIE but not on every machine -- differences might be a subversion/patch issue. Explanation (mainly due to Oliver Bleutgen via this list): the 500 error is generated by zope and appears in the page header. It's part of the mechanism for catching an access violation that leads to a request for login. The problem is that when MSIE sees this error it does not display the rest the login page that follows, but substitutes it's own internally generated page instead. Solutions / Work-around: There are 2 solutions, one based on users changing their preferences the second a code-hack to zope itself. First the easy but sub-optimal work-around: If the user turns off "friendly" error messages in their browser the intercept by internally generated pages can be avoided. Of course, forcing the user to do this is ugly. For a page I made giving detailed user-level instructions, see the following: http://abatonix.dyn.dhs.org/mudcritters/windowsLoginProblem A once-only pointer to this message is generated by the following DTML on my home page ( http://www.mudcritters.com ): <dtml-if "(AUTHENTICATED_USER.getUserName()=='Anonymous User')"> <dtml-if "(_.string.find(REQUEST.get('HTTP_USER_AGENT'),'Windows')>=0) and (_.string.find(REQUEST.get('HTTP_USER_AGENT'),'MSIE')>=0)"> <center> <dtml-if "REQUEST.has_key('MSIEwarning')"> <dtml-else> (Once-only obnoxious mega-sized message.) <dtml-call "RESPONSE.setCookie('MSIEwarning', AUTHENTICATED_USER, expires=(ZopeTime() + 365).rfc822(),path='/' )"> </dtml-if> WARNING: As a user of Internet Explorer on Windows, to login properly <a href="windowsLoginProblem"> click here. </a> </center> </dtml-if><dtml-else></dtml-if> Alternate solution: I modified zope not to give a 500 error as a default in such cases. Then things work fine with all browsers and nobody has to muck with any preferences. I actually think the 500 error in inappropriate in this case so I removed it. The code hack may have other side-effects although since most browsers ignore the 500 error I think it should be OK and it runs fine for me. In line 240 of lib/python/HTTPResponse.py (in the zope directory) change the lines: if type(status) is types.StringType: status=lower(status) if status_codes.has_key(status): status=status_codes[status] else: status = 500 self.status=status to read: if type(status) is types.StringType: status=lower(status) if status_codes.has_key(status): status=status_codes[status] else: status = 200 # GD changed above from 500 as a hack self.status=status Sorry this is so long, but I wanted to save the next poor soul who gets bitten by this.

Upload Photo objects in a localFS

I have a local file system named images. I would like to write-in photo objects. When I write an Image object with <dtml-with images> <dtml-call "manage_addProduct['OFSP'].manage_addImage(REQUEST['id_img'],file,'')"> </dtml-with> there is no problem, but when I try to write a Photo object with <dtml-with images> <dtml-call expr="manage_addProduct['Photo'].manage_addPhoto(id_img, '', file)"> </dtml-with> Zope generate the next error : Error Type: Bad Request Error Value: Cannot add objects of type 'Photo' to local directories.

Thanks in advance for the help or the ideas you can give to me. William.

How do I get an attribute from object, without aquisition
by Max M 07 May '02

07 May '02

I am trying to get at an attribute from an object. First I check if it exists via "hasattr(obj, id)" but the problem is that there are other objects with the id further up in the aquisition chain. So I get some objects that I don't want. How do i limit my hasattr() to just an object and not the aquisitioned attributes ?? regards Max M
