+ in url /zope object name
by Brian Sullivan 06 Apr '06

06 Apr '06

I am running into the problem mentioned in: http://mail.zope.org/pipermail/zope/2003-October/141868.html I have "+" used in a directory name of some content generated outside zope that I want to upload. Preserving the directory name is necessary for the integrity of the data. Why is "+" a prohibited name for a zope object? As a solution Andy Mackay suggests modifying zope to allow "+" in a zope object name. Is there a downside to this?

How to convert characters that have special meaning in HTML to HTML character entities
by Jonathan Bowlas 06 Apr '06

06 Apr '06

Hi All, I have a string that contains a <a href="http://www.mywebaddress.com">link</a> tag that I would like rendered as HTML when output but it only seems to render in the html page like this <a href="http://www.mywebaddress.com">link</a> To replace the characters, I tried this in my TAL: <tal:block tal:define="d_stand row/STANDFIRST | nothing; d_stand_replaced_chars python: (str(d_stand)).replace('>','>');"> <p tal:condition="d_stand_replaced_chars" tal:content="d_stand_replaced_chars" /> </tal:block> But it converted the '>' I replaced with a '>' back to a '>' upon rendering the string in a html page. Any ideas how I can achieve this? Jon

incorporating jmol into Zope
by gf 05 Apr '06

05 Apr '06

Hi, I am a Zope newbie and would really appreciate some help from experienced Zope developers. I am trying to incorporate jmol (a javascript molecule viewer: http://jmol.sourceforge.net/) into some web pages. I think that my confusion may have to do with the use of 'directory relative (../)' versus 'server relative (/)' versus 'absolute url (http://)' paths. The instructions for jmol give an example as follows: <html> <head> <title>Simple example</title> <script src="../jmol/Jmol.js"></script> </head> <body> <script> jmolInitialize("../jmol"); // REQUIRED jmolApplet(200, "load caffeine.xyz"); </script> </body> </html> I have set up a folder in Zope for jmol's files (Jmol.js, JmolApplet.jar): "root/javascript/jmol" I have a Zope folder for the molecule files to be viewed: "root/mycontent/images" I have a dtml method for the actual view page: root/mycontent/view_jmol I would appreciate very much if someone could help translate the example above using my Zope folder structure. I have tried many variations, but they usually end up locking up the browser with a 'downloading applet' message. Related to this is the following question: should I use use the actual file names 'Jmol.js' , 'JmolApplet.jar' as their IDs, or should I use 'dotless' names and just set the correct file types? Thanks for any help and advice you can give. Best Regards, gyro >From the jmol website "General Recommendations": - There is one directory on your web server that contains Jmol.js, JmolApplet.jar, and any other jmol-specific files. For the purposes of this discussion we will call this directory ../your-jmol-directory. - Every web page within your site should refer to ../your-jmol-directory using a relative url. - Directory relative paths which start with . or .. should always be used. Server relative paths which start with / might be acceptable in special circumstances. Absolute URLs which start with http:// are evil and should never be used. - Every page must contain the following HTML command in the head section in order to include the Jmol.js library: <head> ... <script src="../your-jmol-directory/Jmol.js"></script> ... </head> Every page must contain a call to jmolInitialize(codebaseDirectory) as the first call into the Jmol.js library.

Apache2 rewrite gives frustrating 403 error
by Flemming Bjerke 05 Apr '06

05 Apr '06

I hope someome can help me solving this problem: My apache2 rewrite statement to zope/plone make persistently 403 error. (Exactly the same statement has worked before.) From sites-available/zope: NameVirtualHost 213.173.259.117 <VirtualHost 213.173.259.117> DocumentRoot /var/www/virtual/globalfordring.dk ServerName globalfordring.dk ServerSignature On CustomLog /var/log/apache2/globalfordring.dk-access.log combined ErrorLog /var/log/apache2/globalfordring.dk-error.log LogLevel debug RewriteEngine On ProxyVia On RewriteRule ^/(.*)$ http://globalfordring.dk:8083/VirtualHostBase/http/globalfordring.dk:80/por… [L,P] </VirtualHost> If I remove the rewrite rule, a browser reads html-files from the DocumentRoot. I can also browse zope directly: http://globalfordring.dk:8083/portaler/globalfordring. But, when I rewrites this url to globalfordring.dk, I get: You don't have permission to access / on this server. The happens if I exchange RewriteRule with: ProxyPass / http://localhost:8083/portaler/globalfordring ProxyPassReverse / http://localhost:8080/globalfordring I don't understand what is wrong? Flemming The server is a debian stable, Sarge, with apache2.0.54, og zope278 is compiled with its own python 2.3.5. There is a a virtualhostmoster in /.

Problem with ExtFile
by Bruno Grampa 05 Apr '06

05 Apr '06

Hello, i've a problem with ExtFile 1.4.4 installed in a Zope 2.8.6 (on RHES4). The redirection, at the end of file creation doesn't work. To test the problem you have to create these methods: The first one is called 'form': --- <dtml-var standard_html_header> <form action="write" method="post" enctype="multipart/form-data" name="form1"> <p> Insert <p> Id <input type="text" name="id"><br> <b>File</b><input type="file" name="file" value=""> <br> <input type="submit" value="Send"> </form> <dtml-var standard_html_footer> --- The second one is called 'write': --- <dtml-comment> <dtml-call manage_addProduct['ExtFile'].manage_addExtFile(id=REQUEST['id'],title='',descr='',file=REQUEST['file'],content_type='', permission_check=0)"> </dtml-comment> <dtml-call "manage_addProduct['ExtFile'].manage_addExtImage(id=REQUEST['id'],title='',descr='',file=REQUEST['file'],content_type='',create_prev=1, maxx='100', maxy='100', ratio=1, permission_check=0)"> <dtml-var standard_html_header> Ok, done. <dtml-var standard_html_footer> --- If i use manage_addExtImage i got the "Ok, done" message; if i use manage_addExtFile no, just a piece of page (junk?). I can't understand why, can someone help me? Thanks! Bruno

manage_convertIndexes on large-ish catalogs
by Chris Withers 05 Apr '06

05 Apr '06

Hi All, Moving a site from 2.7 to 2.9, so I need to run manage_covertIndexes. The only problem is that, on the main catalog, this sends the machine into swap death. Anyone else experienced this? If so, how did you getaround it? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

bug in zeo runner in Zope 2.8.6 ?
by Vlada Macek 04 Apr '06

04 Apr '06

When I run "zeoctl start" having "user zope" (where zope is an unprivileged user) directive in zeo.conf on a virgin instance directory, at first log/zeo.log file with root owner is created, then the process drops its privileges and timeouts, since it is not able to re-open the logfile. The problem is not imminent when starting ZEO like this: su zope bin/runzeo. That's because there is no chance of creating the logfile as root. I don't know whether this is already fixed in later stable versions, but since 2.8.6 is still a recommended one for at least Plone and maybe there are another fools like me who want to run ZEO unprivileged using zeoctl, I'm reporting it. :) -- \//\/\ (Sometimes credited as 1494 F8DD 6379 4CD7 E7E3 1FC9 D750 4243 1F05 9424.)

Zope and Tomcat troubles
by Mads Munch Hansen 04 Apr '06

04 Apr '06

Hi, Since I installed Zope on my server Tomcat has stoped working, and I was wondering if any of you knew of a solution. When I try to load the management interface for TomCat, all I get is a blank page, the same when I try to log into OpenXchange... I installed zope from the Plone Suse 10 rpm bundle on a Suse 10 box. I hope this isn't too much off topic, but I'm quite sure Zope related. Thanks in advance, Mads Munch Hansen

Zope.org = Zope.com?
by Andreas Krasa 04 Apr '06

04 Apr '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody, it seems that currently all HTTP requests to www.zope.org and dev.zope.org are forwarded to www.zope.com. I find it hard to believe that this is a desired behavior... But if yes, where can Zope itself and Zope products be downloaded? The Zope.com site contains tons of nice eye-candy and marketing-yadayada but no resources for developers whatsoever.

External Methods
by Dennis Allison 04 Apr '06

04 Apr '06

When Zope is run in production (as opposed to debug) mode, modifications to External Methods are not sensed. What's the programatic way to get them all refreshed?
