copying image object?
by Darran Edmundson 07 Mar '00

07 Mar '00

Hi Zopistas, A likely FAQ but it's late, I've been Zoping for 15 hours, ZQR is temporarily unreachable from Canberra, I can't see straight and I'll admit it - I'd like to wake up to the answer ... I simply need to copy an image object (image1) from my globals folder to within an instance of a containerish ZClass. I toyed with manage_addImage() but couldn't find a method to get the raw data out of image1. Cheers, Darran.

ZCatalog again
by Nolan Darilek 07 Mar '00

Ok, it appears that len() isn't what I want. I was under the impression that searchResults() returned an object which functioned as a list, but this wasn't right, apparently. Or maybe it was, *shrug*. :) Here's my current code, which I've modified a bit for testing purposes: <dtml-var standard_html_header> <dtml-calendar> <dtml-call "setCalendar('valign','top')"> <dtml-let d="date.Date()" hasdate="hasProperty(d)" dprop="getProperty(d)" e="getCatalog().searchResults(meta_type='Event', event_date=date)"> <dtml-if e> <dtml-let path="getCatalog().getpath(e[0].data_record_id_)"> <a href="&dtml-portal_url;&dtml-path;"><dtml-var "date.dd()"></a> </dtml-let> <dtml-else> <a href="&dtml-portal_url;/&dtml-date;"><dtml-var "date.dd()"></a> </dtml-if> <br> <dtml-if "hasdate==1"> <dtml-var dprop> </dtml-if> </dtml-let> </dtml-calendar> <dtml-var standard_html_footer> This code generates links as it should. What I'm trying to do though is, if an object of the Event class exists with an event_date which equals the current rendered date, I'd like to link directly to it. I can successfully search for the date using the PTK's search form, so I'm fairly sure that my issues with the catalog are resolved. So, what exactly is being returned by searchResults, and how can I determine whether my search yielded anything, so that I can display a link to the item?

from dtml using REQUEST.form.items(), the order of the form variables is jumbled. is there any way to get the original order that they appeared in the <form>? assuming the browser sends them in the same order that they appear in the <form>? -d -- Adroit | Dyon Balding dyon(a)adroitnet.com.au Internet | http://www.adroitnet.com.au/ Solutions | work: +613 98888522, mobile: +61 0414992604

ZCatalog and dtml-calendar
by Nolan Darilek 07 Mar '00

07 Mar '00

I'm trying to create a dtml-calendar which searches a Z catalog using a custom field on one of my Z classes. I've tested the search by hand, and it seems to work. I seem to be having a few issues with DTML, though. Here is my code: <dtml-var standard_html_header> <dtml-calendar> <dtml-call "setCalendar('valign','top')"> <dtml-let d="date.Date()" hasdate="hasProperty(d)" dprop="getProperty(d)" e="getCatalog().searchResults(meta_type='Event', event_date=date)"> <dtml-if "e"> <dtml-let path="SiteIndex.getpath(e[0].data_record_id_)"> <a href="&dtml-portal_url;&dtml-path;"><dtml-var "date.dd()"></a> </dtml-let> <dtml-else> <dtml-var "date.dd()"> </dtml-if> <br> <dtml-if "hasdate==1"> <dtml-var dprop> </dtml-if> </dtml-let> </dtml-calendar> <dtml-var standard_html_footer> The problem line is <dtml-if "e">. What I was intending to do is perform the code if the search result actually returned something, but this doesn't seem to be happening. What I'd like to do is: <dtml-if "len(e) > 0)"> But, len() doesn't seem to be defined in whichever namespace the code is being run in. I tried: <dtml-call "global len"> before the dtml-if, but this errored out as well. Am I completely misunderstanding the problem which I'm having? Thanks.

It's definately whenever I type in the edit box. At one point I hit enter, and it grew by over 300K. As I type, I can watch the size grow.

Someone even suggested it might be my Motif lib. KDE, afaik, catches all the Motif calls and replaces them with its own widgets. A workmate running Gnome checked the same situation, and the memory leaks in just the same way. scratch another theory. -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Security/AUTHENTICATED_USER/GUF???
by JB 07 Mar '00

07 Mar '00

I have the following structure for my site.. /Home /Public /Members I've set up authentication to happen in /Members via GUF. When I go back to /Home, AUTHENTICATED_USER loses my authentication but when I go back to /Members I gain it back. Any ideas why this may be happening?? thanks jb --

GUF or MySQLUF?
by Ragnar Beer 07 Mar '00

07 Mar '00

Hi everyone, I have to decide which product to use to organise users' access using data from a MySQL database. As far as I can see I could use GenericUserFolder or MySQL UserFolder. Looking at the list it seems that GenericUserFolder is the one that's used more often and that's supported better. Or does it only make more trouble? I would be glad to receive some advice or get some comments. Ragnar

Newbie missing something obvious
by jeffr＠odeon.net 07 Mar '00

Greetings all, I've been running Zope with the zserver web server for a while now, and the setup was a breeze. I've been very impressed with Zope. Now I've been tasked with installing Zope on another machine which is running Apache 1.3.11. From the documentation it looks like Zope+PCGI is going to suit my needs the best, but I'm having problems getting it to work (no surprise, given the large number of HOWTO's on the subject). I can get to the Welcome to Zope! page, and I can view the QuickStart material, but I'm unable to log in to the management interface. I'm also unable to access Zope at: www.mydomain.com/Zope only at: www.mydomain.com/cgi-bin/Zope.cgi so I'm sure it's an Apache/rewrite problem. I've made sure that the username and password are what I think they are via the python script zpasswd.py, and given that I can access the Welcome to Zope/QuickStart material I think I've got Zope configured correctly. After reading through the various HOWTO's on the subject I've got my httpd.conf file entries set as follows (the Gotchas for Zope Beginners HOWTO was very helpful, as was the Zope and Apache on RedHat 6.1 HOWTO, even though they were slightly contradictory on the syntax for the RewriteRule). I'm using RedHat 6.0, Zope 2.1.4, Python 1.5.2, and Apache 1.3.11. Zope was installed from source, Python and Apache from RPMs. Here's the relavent bits from Apache's httpd.conf file... LoadModule rewrite_module modules/mod_rewrite.so AddModule mod_rewrite.c ScriptAlias /cgi-bin/ "/home/httpd/cgi-bin/" # # "/home/httpd/cgi-bin" should be changed to whatever your ScriptAliased # CGI directory exists, if you have that configured. # <Directory "/home/httpd/cgi-bin"> AllowOverride None Options ExecCGI Order allow,deny Allow from all </Directory> # Zope configuration maps /Zope/ to the Zope.cgi CGI script RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope(.*) /home/httpd/cgi-bin/Zope.cgi$1 \ [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] (Note: the RewriteRule is all on one line, without the \. The trailing / after ^/Zope and after Zope.cgi have been removed per the Gotchas for Zope Beginners HOWTO.) I'm at a loss here. I'm positive I'm missing something obvious, but I can't figure out what it is. Thanks for the help, Jeff Robertson jeffr(a)odeon.net

fastcgi report (was how much resource?)
by - 07 Mar '00

07 Mar '00

hi all, i installed fastcgi on my server and added -appconntimeout 0 (as suggested by ppetru). tried both unix and tcp socket. however, i can't get 100% availability. there still exist connection failed (connection refused) errors and incomplete headers 0 errors. my config rhl 6.1, pIII 500M, 776M RAM, oct6 fastcgi snapshot, FCGIServer.py from cvs ver 1.7, zope 2.1.3 i glanced at FCGIServer.py. there were references of max connection (10) and max request(50). will this have any bearing on the connection refused error? do i need to d/l other files instead of only FCGIServer.py? i am also considering mod_pcgi2. can anybody with fastcgi and mod_pcgi2 experience enlighten me? tia -- ------------------------------------------------------ http://www.kedai.com.my/kk Am I Evil?

ZClass question
by Oscar Picasso 07 Mar '00

07 Mar '00

Hi, Something that seems maybe very trivial, but I did'nt find the solution. I have a very simple class ItemId (metatype ItemClass) which is only a subclass of Image and has no property sheet. When I try to create a new instance I get the following message : Error Type: TypeError Error Value: argument file was ommitted Here is my addMethod: ....... <dtml-with "ItemId.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call manage_upload(REQUEST['myimage']) </dtml-with> ...... Where 'myimage' is the name of a field of type file in my input_addForm. I works fine when I use manage_upload with an Image but not when it is a ZClass subclassing an Image. Where am I wrong? Thanks.
