Where do I find out about cookies?
by Jean Jordaan 24 Aug '00

24 Aug '00

Hi Zopers It looks like I'm going to be using cookies now, and I don't find any How-To on cookies. What's the most instructive place to look? "UTSL" is fine as an answer, especially if it points me somewhere, and even more if it's DTML source .. The *ZQR* is a bit too cryptic for me. The *DTML Ref* has a bit more:: 8. Dictionaries are objects that support looking of data by name (e.g. REQUEST.cookies['CUST_ID'] to look up a cookie named CUST_ID). Dictionaries have has_key methods for checking whether a dictionary contains a value (e.g. REQUEST.cookies.has_key('CUST_ID') ) and methods keys , values , and items , for updating lists of dictionary keys, values, and key-value pairs (e.g. REQUEST.cookies.keys() to obtain a list of cookie names). .. but I don't understand yet how 'keys', 'values' and 'items' are going to help me *update* the lists -- it seems to refer only to querying them, AFAICS .. -- Jean Jordaan -- technical writer -- Mosaic Software -- Zope 2.1.6 on WinNT and W2K

import from 216 to 213 fail
by Didier Georgieff 24 Aug '00

24 Aug '00

Hello, I'm trying to import a folder From 2.1.6 (Linux) to 2.1.3 (Linux) and i get this error : Type d'erreur: TypeError Valeur de l'erreur: ('len() of unsized object', , None) I tried to import the zexp in 2.1.6 on Win and it works fine. AFAIK i have the correct objects in the acquired folder. I saw some postings on the list about that problem and i suspect it's the 2.1.3. I'm i correct or do i have to check something else with my zexp ? Thanks. Didier Georgieff

Ok - I propose that image.tag() and .__str__ will: o use the content of the 'title' property if defined o otherwise generate alt="" o include border="0" by default Unless people complain loudly, I'll put on the benevolent dictator hat and have this is 2.2.1 (should be out tomorrow) :) Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

That is the one, I had in mind! > AFAIR I have never packed my database - an attempt to pack > for 10 days, which caused critical errors, was the first one! If you indeed never did a pack before, then you probably have found a new packing bug. In this case, I would expect, that Jim Fulton is very much interested in your corrupted ZODB to analyse the problem. > The newest message on zope-dev mentioned that the bug is fixed and will > be removed in 2.2.0. I use 2.2.0 and have never used older version. My memory may mislead me, but I believe that the above mentioned packing bug was announce shortly after Zope 2.2.0 was released. > Nevertheless, it seems strange to me, that the function containing so > critical error is described in detail in Zope Content Manager Guide - > short intro for beginners. The Content Manager Guide is not rewritten when a bug is detected in one described function. Dieter

Search on ZCatalog or ZSQL in MySQL
by Nestor A. Diaz L. 24 Aug '00

24 Aug '00

Hi, I have a to take a decision to use or not to use the ZCatalog that's because i'm some kind newbie to Zope. Well the history is the following: I have to make a system to store news, so i have to migrate a old system using perl cgi's and perform a search on text files to use Zope as the search engine however i don't know if i have to use a SQL database like MySQL or use the ZCatalog, i need full text search, and ZCatalog fits on the true decision however the current database news is about 350M and i would like to extend it to store images and file, so is possible that at the final year if everyting comes ok it outperforms the 1GB data I read that CodeCatalog.com use MySQL to make their full text search engine, so i think that i can do the same with MySQL using a unique number for each registry and let ZCatalog do a Vocabulary based on the ZClass that get such data? and know how to access the database when someone request a word in the vocabulary based on this unique id? I have a made a prototype in Zope at http://repnet.engendro.com using ZCatalog and the admin console is at http://repnet.engendro.com/admin_html i got based on the ZClass Tutorial from behieve and get it working. Well, i have to make a decision so my last resource is to use a coin ;) Thank you very much (sorry for my poor english :DDD) -- Nestor A.

how can I determine the list of user names?
by jpenny＠universal-fasteners.com 24 Aug '00

24 Aug '00

I would like to construct a pull down of the users defined in an acl_users of a particular location. Say in particular, that /protected/acl_users exists. How do I find (in dtml or in python), the list of names defined in that particular acl_users. To slightly generalize, how would one tree-walk to find the list of all acl_users above a particular object? Thanks Jim

Acquisition, Not! How?
by J�lio Dinis Silva 24 Aug '00

24 Aug '00

I know this sound strange but is there a way to, during execution of a dtml method, when a with tag is used one force acquisition not to be used? example: /root/a/b/c /root/c say <dtml-with "root.a.c"> was a mistake so I dont want the root.c namespace to be imported due to acquisition and instead I want to raise an exception. How can I "turn off" acquisition? I love acquisition, I know its great but I dont want it in a specific case. Is there a way to turn off?
