Um, perhaps a stupid question, but since you are talking about files - is this a Zope object that is in the Zope object database or is it a file that is on your file system? If the last, it will not work. Zope keeps it's objects (files) in it's own database, the ZODB. It is <zopehome>/var/data.fs. You can't read it directly, it is an object database > >another thing i havent understood is that zope.org is running on zope, >then why they donot have url based on 8080. if they are using pcgi then >the url must have been http://zope.org/zope.cgi/index_html isnt this so? No, apache let's you circumvent this. >i also want my url to be simply on http://localhost, what do i need to do >for this. Zope has it's built in webserver, called ZServer. It will run on any port, as long as you have the right privileges. If you want to change the port, change <zopehome>/z2.py It is heavily commented. Look for the http port section, it shouldn't be a problem. Rik

Product doesn't appear in Add List
by sakurai 05 Jul '00

05 Jul '00

Hi, I'm a beginner of Zope. I read Documentation(ZCMG) and trying to create a sample Zope Product, just the same thing as in that tutorial. I did as follows: 1. create Product Distribution Archive (tgz file) in Distribution tab. 2. delete original one (with open-box icon). 3. shutdown zope. 4. re-install it (by extracting tgz in zope directory). 5. restart zope. As a result, it appears in Control_Panel/Products directory (with normal close-box icon), but doesn't appear in the 'Available Objects' Add List. I didn't forget to create factory object. I'm using Zope 2.1.6. Please help. Thanks.

Almost surely, your problem results from the fact that "dtml-tree" does not expect "branches" to be a DTML method and does not pass a namespace to it. I do not know, how you can avoid this (other than changing the "dtml-tree" code. Dieter

alex, IMHO when you try to do stuff using ZClasses and DTML and it starts looking too complex to you then it is. DTML is made for presentation, not for driving an application. a very sound architectural approach, and one that scales very well as your site and organzation grows, is a base of python-based zope products with ZClasses that derive from them. all the logic happens in the python product and all presentation is in the derived ZClasses. this will not only speed up your code but it will also make it easy to control presentation because that is stored in the ZODB and can be manipulated through the web. the only drawback is that a change in the underlying python product code requires you to restart zope. if you're like me and can't stand messy and kludgy code you will appreciate the extra effort spent on writing a real python zope product. for starters look at "How to create a Boring Product" at http://www.zope.org/Members/gtk/Boring/HowTo-Boring . this will explain some of the structure that is needed for a python class to become a "zope product". another guide is at http://www.zope.org/Members/Zen/howto/ProductAPITutorial . for the latest changes that need to be considered when writing a product for zope 2.2 read brian's guide at http://www.zope.org/Documentation/How-To/ProductAuthorUpdateGuide . a good deal of knowledge can be gained from simply looking at the code of products available in your zope install under <zope>/lib/python/Products. jens ---- Jens Vagelpohl jens(a)digicool.com Software Engineer www.digicool.com Digital Creations (888) 344-4332 Got Zope? ---- > -----Original Message----- > From: agould(a)ponzi.oit.umass.edu [mailto:agould@ponzi.oit.umass.edu]On > Behalf Of Alex Gould > Sent: Tuesday, July 04, 2000 21:11 > To: zope(a)zope.org > Subject: [Zope] What is the best way to do this? > > > Hello zope-masters, I humbly ask your advice on several > matters.

zope with large -t
by Bak ＠ kedai 05 Jul '00

hello ppl, what are the bad things that will happen if i increase zope thread from the default to another number, say 25, or 50. will anything bad happen? i guess, the greater number of zope threads will help process request faster, or am i mistaken? i currently have hugh connection numbers from apache (> 200 at one time) and only 15 zope threads. correct me if i'm wrong. thanks -- ------------------------------------------------------ http://www.kedai.com.my/kk Am I Evil?

What is the best way to do this?
by Alex Gould 05 Jul '00

05 Jul '00

Hello zope-masters, I humbly ask your advice on several matters. I am making an internal website for a statewide student activist group with many members. It will hopefully feature discussion boards, a contact database, and a calendar of events. I want to make the users of the site part of the contact database, so that an entry in the database (a name, phone number, etc.) can be easily "promoted" into a user with a password and varying priveliges based on his/her role (volunteer, core member, board chair, etc.) Another feature I want to include is regional specialization - each contact/user, calendar event, and forum has an associated "region" - statewide or a specific campus or something in between. That way a user's default view of the statewide calendar won't be cluttered by irrelevant events, and a search through the contact database would by default only return results pertaining to the user's region. I've tried building some custom zClasses but when things start to get complex the dtml code gets really messy, so I think I should use external methods to do most of the work. Basically I'd appreciate any advice on how to put these ideas into code or pointers to relevant documentation. I don't mean to sound like "here's my very complicated plan, write the code for me", I just need some tips on how to get started. Thanks. -------------- Building highways to reduce traffic is like loosening your belt to reduce obesity.

RFC: is this the best way to make a referal app and a "jump" nav menu *2nd time* menu *2nd time*
by George Donnelly 05 Jul '00

05 Jul '00

Basically i would like people's opinions as to whether i built these things in the "right" way or not. tia! >jump menu *created a selection list and told it to pass a variable (the url of the selected item) called "url" to a method called "jump" which consists of the following: <dtml-call "RESPONSE.redirect(url)"> its a little slow but it works :-) >referral product (as in http://www.recommend-it.com/) i pass the variables on the first page (where people enter name, email, and up to 5 of their friends email addresses) to a method called success here's the problem i think: since i am enabling people to email up to 5 friends, i've got 5 copies of the same email message in the success method inside the sendmail tags. the last 4 are in if statements. i know there must be a better way but i really have no idea. any help? (btw if anybody wants to use these things just email me and ill send you the terribly simple yet useful code. :-) tia!
