Weird (?) Python Script problem
by Bruce Eckel 15 May '01

15 May '01

The following script follows all the rules, I think. It saves fine, and I usually get an exception when I save a script if there's something wrong with it. But when I try to run it, it pops up the "Please type your user name and password" dialog box, and it will not accept my "root" zope admin password. ## Script (Python) "SeminarID" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=name ##title= ## import string, time order_id = string.join(string.split(string.strip(name)), '') # Remove spaces idstring = '' for c in order_id: if c in string.letters: # Take only characters idstring = idstring + c order_id = idstring[0:20] # Take only the first 20 characters order_id = "%s%x" % (order_id, time.time()) # Combine with current time in hex for unique ID return order_id Most current information can be found at: http://www.mindview.net/Etc/notes.html =================== Bruce Eckel http://www.BruceEckel.com Contains free electronic books: "Thinking in Java 2e" & "Thinking in C++ 2e" Please subscribe to my free newsletter -- just send any email to: join-eckel-oo-programming(a)earth.lyris.net My schedule can be found at: http://www.mindview.net/Calendar ===================

ZCatalog + Directory product question
by J�lio Dinis Silva 15 May '01

15 May '01

Hi, supose you have a product with two classes: MyCategory | ---------- MyLink Both classes are CatalogAware. The ideia of this classes is to implement a Directory like yahoo (think about the Yiahw product). Now I start creating my Directory. My classes have a property "active" that I use to activate and deactivate some parts of my Directory. Now I want to search in my Catalog in which I have MyCategory and MyLink instances catalogued. When I do a search I want to retrieve only results with the "active" property "on". This is ease no big deal. But I want to guarante that all PARENTS of a given Mylink are all with active property "on". Yes no big deal, for each result from my search I run trough the getPath(data_record_id) or even PARENTS and check for each Parent if they are all with active==on. Well the problem arises when you have 30 results in your search and all are Mylinks in a directory depth path of 10 category... The search becomes to heavy,i.e, scalability is compromised. I'm thinking I could use the zope security engine to do the active/deactive trick, i.e, when I deactivate one MyCategory I uncheck some security entry, then listing my directory I do a dtml-in with skip-unauthorized, and when I do a search I try to getObject MyLink's results as a anonymous role and then skip_unauthorized. I think this skip_unauthorized could be the solution for this ZCatalog+Directory product scalability, because instead of running trough the PARENTS and check a property, I will be using zope's internal security mecanism. Any hints, Júlio Dinis Silva _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Product Installation via the Web?
by Rahsheen Porter 15 May '01

15 May '01

I'm behind an extremely anal firewall here at work and was wondering if there is a way for me to install products on my Zope server via the web. I noticed ZInstaller (I think that's the name) on ZopeZen.org, but I can't even install that for reasons mentioned above :) Is there any way I can get around this? I was thinking maybe uploading the packages into the ZODB and somehow doing evil DTML tricks to get it installed, but I don't know enough DTML to fathom whether something like that is even possible. Any ideas? --- Rahsheen Porter __________________________________________________ Do You Yahoo!? Yahoo! Auctions - buy the things you want at great prices http://auctions.yahoo.com/

Wow! (Please note: I changed the list to the zope mailing list) Can anyone explain this? Marc, what type are those objects? (Is "bowerymarc" a Folder? Is index_html a DTML Document or Method?)

Postgresql Adaptors
by Alex 15 May '01

15 May '01

I'm migrating some code that uses ZMySQLDA to ZPoPY, and just figured out that ZPoPY does not convert datetime fields to time objects when I select them. Is there any pgsql adaptor for zope that does this convertion? (zmysqlda does it) I thought all database adaptors had some kind of standards, like data type conversion, but it doesn't look like this is the case. thanks Alex

RE: [Zope] Xron: installation problem (SUSE 6.4, Zope 2.3)
by Loren Stafford 15 May '01

15 May '01

Homan: I don't know how others are getting along with Xron; that's a question better asked on zope(a)zope.org. I've copied that list. I hear about Xron from others mostly when it doesn't work; rarely when it does work. How about it folks. We need some positive feedback here. Has anyone successfully installed and used Xron on Zope2.3, SUSE 6.4? Did you run into the lock-up on install problem?

Auth w/ Virt. hosting
by Jason C. Leach 15 May '01

15 May '01

hi, I have 3 sites hosted on 1 zope server. Apache is on the front re-writing the URLs and interacting w/ SiteRoot on Zope. Zope seems to always ask me for a user/pass when I do somehting like edit a file or change folders. Is this just the way it is, or can I get around it? j. ...................... ..... Jason C.

by Bocquillon Philippe 15 May '01

Hello, Using a Zope module (RDFSummary), I have the following error on Windows NT: Error Value: (10060, 'winsock error') which is a timeout. Could this be because I am under a proxy server? How do I specify to Zope the presence of a proxy server? Thanks in advance Philippe
