An ex-virgin discusses his first big night with Zope
by Thomas 16 Jan '00

16 Jan '00

Hi all, I have been building my first project based off of Zope. Basically, it is an Article Store with an Interface built in for content folk to add and edit new articles. The other feature is a review function where users can rate each article and give some room for them to provide some of their unique thoughts. This site is based in China, so we need to control/(and perhaps edit) these reviews before publishing them live, and so the reviews first get checked by the content team and then can be published. (this review check is done through the content interface). I wanted to write a general review of Zope and my overall feelings to the list. My background: I have been coding static pages for some time and recently (the past few months) have done very, very basic editing in Zope. I know some basic Javascript and am starting to delve deeply into Python. (as a result of Zope) I have never solely owned a large project and in the past have heavily relied on teammates to build Zope sites. With the completion of my project described above, I am no longer a Zope project virgin. At first, I found Zope's dtml scripting deceptively simple. I thought, "oh, its just like html", but that illusion was shattered after getting a little deeper. At that stage, I was very frustrated and discouraged by my slow progress. I honestly thought I would never understand Zope. I guess this is the steep learning curve everyone talks about. After hitting my head against my keyboard a few time, I decided upon another strategy. I went through all of the Zope Documentation files and then started to go through all of the relevant how-to's (mainly on Zclasses, Aquisition, namespaces, Zcatalog, etc.) Then I hit the list. I had been accumulating a very large box full of Zope mailings, but I never went through them too seriously. I went through about 1000 Zope postings last week. I have to thank this list for helping me out so much. (indirectly albeit) At that stage, I was ready to take on Zope again. I have been at it for the past 8 days nonstop, and my project is almost finished. I am very pleased with my *quick* ability to pick up Zope. My advice to all the newbies out there... stick with it. You will be proud of yourself in the end but you need persistence. I still have questions on some tags and their behavior and Aquisition, but I feel confident enough that I'll get a handle on them soon enough. I have a few ideas which might help folks on the steep learning curve of Zope. 1) Create an FAQ. I think I have already posted questions on the list which never got answered because clueless newbies asked them 100's of times before. I think the questions which hit this list often should be compiled and put on the Zope site in the mailing lists section. This would a) help newbies out and b) sort out repetition from the List. Question is: who will do this? 2) Take apart a product or two. I went through KMnetNews which helped me out a lot. Not only did it provide ideas in action of how Kevin built the product, but it also helped to show me proper dtml syntax. Just wanted to post my thoughts for the list and again thank everyone who contributes. Tom

Re: [Zope] SQL7 connector?

My understanding of it is that as long as you don't use any SQL7 specific features, you'll be ok. You might also want to check out FreeTDS (www.freetds.org) - note that currently it is not multi-thread safe, so you can either: hack the SybaseDA to do the Thunk hackery lock thing, or run zope with -t 1 to make it single threaded (performance lossage) The easiest thing to do would be to just download the Sybase libraries for linux (note that you'll need 11.9.2, not the old 11.0.3 version), and give it a go.

I've ALWAYS thought it was: <dtm-var "aMethod(_.None,_, uncle='bob')"> Note the variables, they are very important :) IIRC, I'm pretty sure I got this from either you (Michel) or Kevin Dangoor in this mailing list a long while back. Maybe its time somebody put this more prominently in the docs, cuz it sure gets asked a lot, and I think there should be one "official" way of doing this ;^).

SQL7 connector?
by ozric 15 Jan '00

15 Jan '00

Does anyone know if and/or how to connect to a MS SQL7 database? I am still trying to make my Dept see the light and let me set up a production server using Zope and Linux. The biggest problem is that we and currently moving from Sybase on HPUX to SQL7 on NT (don't say it.. please). I need to reassure them that Zope will be able to get to the SQL7 server now or sometime soon. I am going to use MySQL as the demo but they are just going to say "what about the SQL7 stuff". Any help or advice would be splendid. -- "...I'm not one of those who think Bill Gates is the devil.

Acquisition on dynamically created objects
by Sascha Matzke 15 Jan '00

15 Jan '00

Hello, I have a class in my zope hierachy which implements an __getitem__ method and return objects which are created on the fly (or taken from a volatile (_v_) dictonary). What do I have to do if I want those objects to take part in the acquisition machinery.

Problem Packing Zope Database
by Shaw, Mark 15 Jan '00

15 Jan '00

Oh Nooo!! I am in the process of creating a Zope based web site. I just now encountered a problem where if I "Pack" my database from "Database Management at /Control_Panel / Database", I cannot restart the database. The error message that I receive is as follows: I can restore a relatively recent copy of the DB and restart it, but as soon as I pack it, it gets hosed again. I guess that's the last time I pack my database without first backing it up. But who wants a db that they can't pack. Bummer!!!! Do I start over with Zope again or do I change my server engine???? This was going so well :-( Running Zope-2.1.2 on RedHat 6.1. ________________________________________ [root@www5 Zope-2.1.2-linux2-x86]# ./stop [root@www5 Zope-2.1.2-linux2-x86]# ./start [root@www5 Zope-2.1.2-linux2-x86]# Traceback (innermost last): File "/opt/zope/Zope-2.1.2-linux2-x86/z2.py", line 436, in ? exec "import "+MODULE in {} File "<string>", line 1, in ?
