JOB: Fantastic Zope position at Fortune 100 company
by Paul Everitt 19 Sep '00

19 Sep '00

Hello friends. We at Digital Creations have been pretty low-key about promoting job announcements. I'll break the tradition, but only to promote someone else's job position. The reason I'm getting involved is the project is a Big Deal for Zope and the folks involved are great people. For those not interested, please grant me a "get out of jail free" pass on this one. :^) In the very near future, a Fortune 100 media company will launch a new web initiative for which Zope is the content management platform. Digital Creations has been working closely with the company on the architecture for the project. With the initial success, the company wants to augment its internal Zope technical staffing. The job opening is for someone with strong Zope/Python skills, preferably on Linux. Background in web design, information architectures, and project management are beneficial. The vision for this project is quite exciting indeed. If any of you are interested in a prime-time Zope position in New York City, contact me (paul(a)digicool.com) and I'll pass along your contact information. (Update: The site did a soft launch last week, so time is of the essence!) --Paul

Desperate Zope is crashing ....
by Daniel Rusch 19 Sep '00

19 Sep '00

Hey all, I have a major problem! Our Zope site is crashing every few hours. I've grep'ed the python processes and they are still running but I can't access any pages. It's very strange because it just started happening last thursday. Prior to that we had no problems. No changes were made to the site. I know that software just doesn't start to have problems that something must have changed but I can't identify anything. One thought is that the user community is hitting an area of the site that they haven't in the past, but how do i find it??? Details: Zope version: Zope 2.0.1 (source release, python 1.5.1, linux2) Python version: 1.5.2 (#6, Sep 22 1999, 10:32:58) [GCC 2.8.1] System Platform: sunos5 We have bounced the box, but still it dies??????? I don't even know how to start debugging this ????? I've crawled through the Z2.log file to no avail. DR

dtml-tree urlparam
by J�lio Dinis Silva 18 Sep '00

18 Sep '00

Hello all! Suppose I have a page who needs some dinamically generated params in order to be rendered. Suppose this page also has a dtml-tree. I found that to add extra params to the url created I can use the urlparam param :-) But suppose instead of passing "arg=1" I want to pass REQUEST['QUERY_STRING']. I thought urlparam would do the trick but using urlparam=QUERY_STRING the string passed is "QUERY_STRING" instead of the value of QUERY_STRING. Is there another param to do what I want or do I have to go into the source to hack dtml-tree to force to pass my QUERY_STRING parameters? thanx to all, Julio Dinis Silva _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Dynamically render DTML?
by Mark N. Gibson 18 Sep '00

18 Sep '00

Is it possible to return dtml from python, and have it rendered correctly on the page? for example, the python might look like this... def get_header(somevar=1): if somevar==1: return '<dtml-var standard_html_header>' else: return '<dtml-var other_html_header>' The dtml document in the zodb might look like this... <dtml-var expr="get_header(1)"> Body text.... <dtml-var standard_html_footer> When this gets rendered, it's as if the dtml document had <dtml-var standard_html_header> in place of the get_header call. I understand how to call external methods from dtml, etc. I just want to know if it's possible to get the string returned rendered as dtml. Mark --------------- Mark Gibson Kaivo, Inc. www.kaivo.com

Re: [Zope] FSSession problems...
by Ayhan Ergul 18 Sep '00

I am also experiencing the problem of two different users sharing the same session inadvertently. However, in my case, I can disqualify a few things that were previously discussed as possible reasons why this happens and add some more info: - Zope is running without Apache - Clients have different SessionUID's assigned (2580309312979106 vs. 26209573571042815) - Clients are netscape on linux running on the same computer as zope vs. netscape on nt4 in the same local network as the other (with no caching in between). - I have the two browsers open and I can freely modify page on one, reload the same page on the other and see the updates reflected. Any clues appreciated.

ZODB Edit

Is there a way to edit Data.fs independent of the Zope interface? >From what I can tell I have a remnant of a deleted product still "registered") and therefore can't add a new/similar product because it has an identical class-id. The product is a z-class so it's gone from the product menu and there aren't any files associated with it to remove. Is there any way to edit ZODB directly or to have it "scoured" clean?

This is a security feature to prevent a user with partial management rights in a subfolder to affect permissions for objects outside its area. I think (am not sure!) that in your case, the "protected" context is not used as your objects are in fact outside "protected". Dieter

Or am I trying something which isn't possible to do? SQL methods do *NOT* look at the DTML namespace, only at the REQUEST object! You must either put your parameters into REQUEST (--> REQUEST.set) or call the SQL method with explicit keyword parameters. Dieter

Re: [Zope] file upload and MySQL

This is an FAQ (answer found in the searchable list archive!). Uploaded files are "ZPublisher.HTTPRequest.FileUpload" instances. They behave like files with the additional attributes "filename" and "headers". To get the size, you may need to use "seek" (to the end) and "tell". You make this information available to an sql method as you make any parameter available for them: either: put them in the REQUEST object (--> REQUEST.set) or: call the sql method with keyword parameters Dieter
