DOM and Zope
by Jesper Holmberg 09 Dec '01

09 Dec '01

This code works fine in the python (2.1.1) interpreter: from xml.dom import minidom myDoc = minidom.Document() myEl = myDoc.createElement('jeppe') myEl2 = myDoc.createElement('henning') myDoc.appendChild(myEl) myDoc.insertBefore(myEl2, myEl) print myEl2.parentNode print myEl2.nextSibling However, when I put this code in a Zope (2.4.2) product, and run it, I get an error on the last line: Error Type: AttributeError Error Value: nextSibling with trace ending in: File /usr/lib/zope/lib/python/xml/dom/minidom.py, line 74, in __getattr__ AttributeError: (see above) So for some reason, the node myEl2 is not correctly inserted in the DOM. It knows its parent, but not who is it's sibling. In fact, if nextSibling were None, there wouldn't be an error, but now it doesn't even know it has an attribute with this name. Does anyone have an idea what could be the problem? TIA, Jesper -- Jesper Holmberg |"But how can | jesper.holmberg(a)enst-bretagne.fr | one be warm | ENST Br, BP 832, 29285 Brest, FRANCE | alone?" |

RE:Editing dtml content for non-techies

Message: 12 Date: Fri, 07 Dec 2001 11:53:22 +0000 From: matt carey <matt(a)textmatters.com> To: <zope(a)zope.org> Subject: [Zope] Editing dtml content for non-techies i'm wondering if anyone knows of a dtml editing tool (or soemthing) that would allow for the editing of content within a dtml page on zope by a non-techie? we have a zope site for a client who wants to give the editing and content updating tasks to various members of staff. they don't want to use the management interface as they do not understand html/dtml. what we need is a way they can view just the content (so the dtml tags are present but hidden and not re-written) and edit that. we are planning to allow downloading/uploading of files useing webdav. any ideas or suggestions would be fantastic! cheers matt hello mat, Does your client want to edit only content on the website ?? I think then you can make some content management forms and your client wont see HTML/DTML tags. He will just type the matter in the forms and it will be there on the website. besides you dont even have to upload any files separately. I have almost finished creating such forms for my company. If can help you if this is what you want !! Sanket.

security audit
by Erik Myllymaki 08 Dec '01

08 Dec '01

I am trying to make a security DTML script so that when I am logged in as a manager, I can see what Roles have 'Access contents information' and 'View' permissions to the various directories and files that I am working on instead of bringing up the security screen all the time. The problem I have is with acquired permissions, they do not show up using my method, so only if the Role is explicitly set on the object will this work. Any suggestions to make this OK with acquired permissions? <dtml-if "REQUEST.AUTHENTICATED_USER.has_role('Manager')"> <table border="1"> <tr><th align="left">Access</th><th align="left">View</th></tr> <tr><td> <dtml-in expr="rolesOfPermission('Access contents information')" mapping=1> <dtml-if selected> <dtml-var name><br> </dtml-if> </dtml-in> </td> <td> <dtml-in expr="rolesOfPermission('View')" mapping=1> <dtml-if selected> <dtml-var name><br> </dtml-if> </dtml-if> Thanks, Erik Myllymaki erik(a)pacific-shores.com

FYI: ZC At IPC10
by Paul Everitt 08 Dec '01

08 Dec '01

Hello everybody. We at ZC would like to share with you info on our plans for attending IPC10. The good news is that business is going well for us, leaving us pretty booked. Unfortunately this means that we can't spare the majority of the company to attend the Zope Track at IPC10 in February. The other good news, though, is that we're committed to sending some senior people, including Tres, Jim, and me. As available, we'll send a few others. We'd still like to see everyone and give you a chance to put some faces to names. As such, we're considering having a Zope open house here in Fredericksburg, either on Thursday or Friday after the conference. If you would be interested in coming to see us, please drop me a line. --Paul

Hi Tim, First of all, questions related to Zope problems are best asked on the Zope mailinglist; the webmaster(a)zope.org address is primarily meant for issues on Zope.org only. That said, I can confirm that we have seen problems with IE 5.0 and Zope, but only when it comes to passing on Authtication information. However, it may well be that IE 5.0 has got other problems as well. Either way, the default index_html page on a freshly installed Zope warns against using IE 5.0. Maybe someone on the Zope mailinglist can provide further insights, I cc-ed the list. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

using mysql LOAD command to store values into table from zope mgt screen (is it realistics?)
by Hamzat Kamal 08 Dec '01

08 Dec '01

Hi, I have my zope server and mysql server at the remote site. I can logged in to my zope server from my local computer but yet to be able to log into mysql server. I have already created a table into database inside mysql server at the remote site through the Mysql database adapter (MySQLDA) created inside the zope server. I didn't want to use INSERT COMMAND to store values into this table (for obvious reasons) so i would have preferred LOAD command. I have already tried these ffg. from the MySQL Database Connection management screen but all failed.. LOAD DATA FROM "C:\text.txt" INTO TABLE test error :ProgrammingError Error Value: (1064, 'You have an error in your SQL syntax near \'from "c:\\text.txt" into table test\' at line 1') LOAD DATA LOCAL INFILE "text.txt" INTO TABLE test LOAD DATA LOCAL INFILE "c:\text.txt" INTO TABLE test error:The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /jambng_db/manage_test. Reason: Document contains no data Please assist. regards. kamal

Version Lock Confusion
by Dan Shafer 08 Dec '01

08 Dec '01

I have created a Version on my Zope site. I am not working in it at the moment. I try to delete a DTML document that has never been opened or modified in the version, but Zope won't let me delete the document. I get an error that looks like this: Error Type: VersionLockError Error Value: ("'\\000\\000\\000\\000\\000\\000\\026\\003'", followed by the name of my new version object. I can edit files just fine but I can't delete them. From what I read in the docs, this shouldn't be the case. So what am I either missing or doing wrong? -- Dan Shafer, Author-Consultant http://www.danshafer.com http://www.shafermedia.com

Remote User Mode, NT Authentication with IIS and Zope
by Michael Wills 08 Dec '01

08 Dec '01

Hello, I have been to get jcNTuserfolder to work for several days now. I am fairly new both to Zope and to NT but this is the best solution to our organization's needs right now. I have been following the directions but I seem to be missing some steps. I have gone through: How-To: HOWTO use Zope and IIS together in remote user mode Which included going through: How-To: HOWTO use Zope and IIS together in remote user mode This first question might solve the problem: how do I put Zope in remote user mode on Win2000 running as a service? I am on Win2000, IIS 5, latest stable release of Zope, and the latest jcNTuserfolder. After installing the product and adding the jcNTuserfolder, the only users that are listed in the user folder are the local domain users. I have disabled anonymous access but I can't yet grant access to local users at this point, not to mention users from other domains. I realize this is fairly vague, but I an not yet sure which questions to ask. I have checked the FAQs, newsgroups, the web, etc. Any tips to some clear directions would be greatly appreciated.

More product writing problems
by Tille, Andreas 07 Dec '01

07 Dec '01

Hello, I want to write my own instance of FOlder product maintaining a set of keywords. This worked so far but I want to strip some spaces from the keywords the user might have prepended/appended. I wanted to use the following code: ob=MyFolder() ob.id=str(id) ob.title=title ob.keywords={} for kw in keywords: kw=kw.strip() if kw != '' : ob.keywords.append(kw) self._setObject(id, ob) ob=self._getOb(id) Well, obviousely this is intended to work under python2.1. Because of a broken Zope 2.4.2 installation which does not show up my product in the products folder mysteriousely (see thread "Problems writing a new product") I use Zope 2.3.3 (Debian/GNU Linux Woody zope_2.3.3-1) which depends from Python 1.5 - at least under my system. If I link /usr/bin/python to /usr/bin/python2.1 zope does not start because of some modules (namely 'os') are not found. So how can I write this code safe even for older Python versions or does anybody has an idea how to fix the broken Zope installation? What other logfiles could I observe. I did not found any others than Z2.log. Kind regards Andreas.
