Is zPatterns nessecary? What do you want to achieve? - The equivalent of foreign keys in relational Databases, for instance the automatic deletion of article1 if article1.author2 == 'user1' when you delete user1? Then I would use a completely different structure than the one above, perhaps a zclass which is instanciated for every author and can contain articles. - Or do you just want zope not to throw an exeption if ._[author2] doesnt exist? Then it should be possible to write a small method which emulates <dtml-var my_variable missing> for variables which contain the id of an object. (The functional analogon to the not working <dtml-var "_[my_variable]" missing>). So you can do <dtml-var "test_and_return_email(author=author_1)"> cheers, oliver

How do You guys manage integrity in Zope
by Max Møller Rasmussen 02 Apr '01

02 Apr '01

i have made a few sites in Zope by now, and I often have problems with integrity in the database. Ie. with a structure like this: users user1 user2 user3 ... articles article1 article2 article3 If I have an author field in "article1" that is the id of "author2" and I then delete "author2" I get an error when trying to get the authors properties like e-mail, name etc. Off course I can test to see if the author exists before trying to pull out the data, but this seems like a messy way to do it. How do the rest of you guys solve this problem? Is zPatterns nessecary? regards Max M

Checking for authenticated users...
by Ixokai 02 Apr '01

02 Apr '01

I'm in the process of working with Zope for the first time as a learning exercise.. So far, I'm rather impressed with the immense potential of what I can see myself doing without a great deal of difficulty. The 'skeleton' index_html in / that provides a standard look for everything, and so on, and so forth... Its just nice. Now i'm working on my first form, and am having just a bit of trouble. Perhaps its because I've never ended up using .real. HTTP authentication in any other website I've done :) I want the form to insert the person's username into the form if they have logged in, otherwise, not enter anything and just print "Unregistered User" on the webpage. Here's what I'm trying, which simply isn't working :) It prints 'Anonymous User' instead of 'Unregistered User' if my user isn't logging in. <dtml-if expr="AUTHENTICATED_USER != 'Anonymous User'"> <input type="text" name="From" value="&dtml-AUTHENTICATED_USER;" size="36" maxlength="36"> <dtml-else> Unregistered User </dtml-if> What am I doing wrong? Thanks for your help. :) --Ix

Re: [Zope] Getting a date into an object title - DISREGARD

Why is it that within 5 minutes after posting a notice on this list that I figure out a solution to the problem? Is there something therapeutic/magical about this list?

Form processing in Zope
by Gitte Wange 02 Apr '01

02 Apr '01

Hello, I have now found out that my problem isn't just a select box in Zope, but it is all form processing. I am mostly a PHP programmer so I am used to when you make a text field in a form named e.g. Name it will (when you have hit the submit button and the script you have set as actionscript receives the form) be declared as a variable named Name. But I guess Zope doesn't work this way. So how does a dtml document recieve the fields in a form ?

Re: [Zope] zopesh

I now my poor english is not enough good to explain my problem this is the reason why I sent you the example below. I think this problem is connected with the new zope release (2.3.0) because zopesh works perfectly with the previous release. Is there somebody who has experienced the same problem using zopesh with zope 2.3.0 ? If so, please help me!!!

Multiple site deployment
by Chui Tey 01 Apr '01

01 Apr '01

The project I'm doing will be deployed to several intranet sites. I'm developing content and logic in dtml plus a few external methods. Each site deployment will be customized. The customization is simple: basically changing the standard_html_header, smtp server name, and things like that. Dealing with software updates can be somewhat of a problem since I'll have to recustomize every data.fs before deployment? How are other developers handling this kind of customization problems? The Directory View from CMF looks to be useful in storing some of the customized dtml in the file system. I've tried ExtFile but it doesn't have external dtml documents. Has anyone used zope with configuration files before? Chui
