inserting half a dtml tag into a zclass
by Tim Hicks 28 Dec '00

28 Dec '00

OK, I'm sorry for the wierd title, but I can't really describe what I want to say very easily in one line. Basically, my problem is this; - I have a zclass called DEHS with catalog_aware and dtml_document as base classes. - DEHS instances have a selectable property of public/private. - I want to be able to make it so that if the property is set to 'private', then only people on a particular network may access it. So, here is what I have done (and it works), <dtml-call "REQUEST.set('available', 0)"> <dtml-if "propertyLabel(availability) == 'private'"> <dtml-call "REQUEST.set('available', 1)"> </dtml-if> <dtml-call "REQUEST.set('dom', _.string.split(REQUEST.REMOTE_ADDR, '.'))"> <dtml-if "dom[0] == '192'"> <dtml-if "dom[1] == '168'"> <dtml-call "REQUEST.set('available', 0)"> </dtml-if> </dtml-if> <dtml-if "available == 1"> <dtml-in PARENTS> <dtml-let PARENT="_.getitem('sequence-item')"> <dtml-if "PARENT.hasProperty('dehs_site_root_folder')"><dtml-call "REQUEST.set('restricted', PARENT.absolute_url())"></dtml-if> </dtml-let> </dtml-in> <dtml-call "RESPONSE.redirect(restricted+'/restricted.html')"> <dtml-else> <dtml-var standard_html_header> <dtml-var standard_html_footer> </dtml-if> So, what's the problem I hear you ask. Well, I don't really want all this code to be visible (or breakable) in every DEHS instance. What I would really like to do is have this, <dtml-var privacy> <dtml-var standard_html_header> <dtml-var standard_html_footer> </dtml-if> where, <dtml-var privacy> is just all of the code that I have above s_h_h. However, zope will not let me do this because I end up with a <dtml-if> that is missing its closing tag, and one that does not have an opening tag. I realise that I there are products already designed with the sort of functionality I am after built in, but I will not have much influence on the products that will be available on the server that this site will end up on... which is why I'm doing it in this way. Any input is much appreciated. cheers tim

can't change zclass meta type
by Geoffrey L. Wright 28 Dec '00

28 Dec '00

I can't seem to completely change a zclass meta type. When I make a change on the "basic" tab of the zclass, my change seems to take, and the new meta type is displayed in the form. But when I try to add an instance of this metatype, I still see the old meta type name in the dropdown. When I try to reference objects by metatype in my code, the new name does work, so it appears that the new metatype is ... mostly ... applied. Is this a bug? Or is the some other location where I also need to change this info? -- Geoffrey L. Wright Developer / Systems Administrator (907) 563-2721 ex. 4900 http://www.integritysi.com

Here is a problem I'm encountering while installing Zope through PCGI : I can get the first screen but can't log into management screen with "superuser" and "123" Yet it works perfectly with ZServer installation instead of PCGI installation I have tried all sorts of combinations with file /var/zope/access, no success As error messages, at first I got """ Traceback (innermost last): File "z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "/usr/share/zope/lib/python/Zope/__init__.py", line 110, in ?

Re: [Zope] SiteAccess / SUPPRESS_ACCESSRULE bad

Fortunately, I have solved the problem myself. Thanks for everybody for looking into my problem. For the curious: In the apache httpd.conf I made a proxy to the Zope web, except for the home page '/'. Because in the SiteRoot I pointed the '/' as the root, so http://www.mydomain.nl:9673/SiteRoot/manage_main points the Zope management form to '/'. Because there's no Zope at '/', deleting the SiteRoot from Zope management failed. Changing in apache httpd.conf the / to ..:9673 solved this.

is it possible to import from Excel
by K H Subrahmanyan 27 Dec '00

27 Dec '00

Hello, Now we have developed some database using gadfly in zope. Actually there are some datum which are there in Excel. I would like to know is it possible to import all that datum from Excel to zope database, instead of giving all the data to zope manually. Actually all those data are the Emp. records. Currently they are maintaining it in Excel. Now they want to make it web based stuff. We have developed a tool for that. Since all that data are there in Excel I wanted some stuff to import that. Hoping your reply. bye yours subrahmanyan.

Zope eating CPU/RAM - how do I find the culprit?
by cg＠cdegroot.com 27 Dec '00

27 Dec '00

Our production Zope machine has developed a habit over Christmas where it starts eating CPU and RAM (one Python thread on 100% CPU time, and I've seen kernel messages indicating that Zope was killed because it hit an out-of-memory condition which means it sat on ~500Mb RAM). I'm completely in the dark about what causes this (probably some of my own code, I installed some new bits a couple of days ago), but what's worse: I really don't know how to set about finding the problematic code. Is there a way to find out what code a thread is running? -- Cees de Groot http://www.cdegroot.com <cg(a)cdegroot.com> GnuPG 1024D/E0989E8B 0016 F679 F38D 5946 4ECD 1986 F303 937F E098 9E8B

SiteAccess / SUPPRESS_ACCESSRULE bad (urgent)
by Edwin Martin 27 Dec '00

27 Dec '00

Hello, I'm running an Zope website behind an Apache proxy. Because Zope is running on port 9673, some links pointed to this port and the URL showed mydomain:9673... To prevent this, I installed SiteAccess and I put a SiteRoot in the root of my Zope web. I entered: Base: http://www.mydomain.nl/ Path: / Since then I can't access http://www.mydomain.nl/manage. I do get the password-box and frames, but both frames show 'Not Found'. Not Found The requested URL //manage_workspace was not found on this server. Opening the frame in a new window and removing the second / doesn't solve the problem. I looked up the docs of SiteAccess and found setting a environment variable and restarting Zope would help. So I tried that: # SUPPRESS_ACCESSRULE=1;export SUPPRESS_ACCESSRULE # env ... shows SUPPRESS_ACCESSRULE=1 ... # /etc/init.d/zope restart Restarting Zope... done. Unfortunately, the problem is still there. Anybody knows an answer to my problem? I really hope so, it's a live site! Bye, Edwin Martin.
