Found an answer: <http://www.zope.org/Members/spinwing/ZSQL_Results> http://www.zope.org/Members/spinwing/ZSQL_Results This is super handy if you need to do any processing, filtering, or whatever on your resultset from a Z-SQL call before displaying your data in dtml or zpt templates.

RE: [Zope] DTML Document ids

Are you putting this in a DTML Document, or a DTML Method? AFAIK, that won't work unless it's in a method.

Now, can you please elaborate a bit (or point me to some doc) on why I should use the getId() method instead of the id attribute? It happens that I have exactly this bad habit and I have quite a lot of code where I use id attributes :-( Thank for the reply, __peppo _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Zope Evaluation
by Gabriela LÃ³pez Ruiz 17 Oct '03

17 Oct '03

Hi all, I'm evaluating Zope platform and Zope products, just in a general way. My main goal is to find out if I can use Zope as a simple platform where we could develop and delivery web-based applications. The principal characteristics that a platform like what we are looking for has to have are: licenses (it has to be open source), if it has a rich set of products, it it has a great users community, if there is many available documentation (in Internet, in bookstores, etc), the possibility of integration with external databases, if it has a security model (and how strong is that model), if it gives the possibility of avoiding the interaction of a web master in all deployments, how many languages does it support and which ones, recommendations concerning the base product to be taken, which of these options is better and why: CMF + ZOPE, ZOPE only, CMF + PLONE+ ZOPE, if its easy installing new products and developing applications, about Clear Case integration, and what about stability/performance I know that this is a very large list of characteristics, but I will be very thankful if you can give me your opinions as you have been working in this platform more time than I have. So if you can give me your opinion or can send me an URL or some articles where I could find the description of some of this characteristics, it would be better. Regards, Gabriela. _________________________________________________________________ Charla con tus amigos en línea mediante MSN Messenger: http://messenger.yupimsn.com/

can i ask a question about a possible zope book?
by Chester, Pam [ELS] 17 Oct '03

17 Oct '03

Hi-- Would it be possible to send the following question to subscribers to your list? I'm an acquisitions editor at Digital Press, and our foreign rights office just asked me if I'd be interested in publishing the English version of a recent German book on Zope (Zope--Content Management and Beyond). It's a collection of articles edited by Stephan Richter. If you feel it might be worthwhile to publish such a book, would you be willing to email me at p.chester(a)elsevier.com? If I'm going to persuade my boss that there's a market for this project, I'd need people to answer a couple of questions. (If this is not an appropriate query for your list, please just let me know.) Thanks. Pam Chester Digital Press, an Imprint of Elsevier Burlington, MA

boston.com: The demo gods strike again
by Wade Leftwich 17 Oct '03

17 Oct '03

I was talking with a friend about options for replacing a crufty old CMS, written in .asp, that manages 80 websites. I said, "Hey, let's look at boston.com, the new Zope showpiece!" But, at 9 o'clock this morning, boston.com was painfully slow to load. Is this a regular thing? Next time, of course I will check the site *before* I open my mouth. -- Wade Leftwich Ithaca, NY

RE: [Zope] add LocalFS in python

[Dennis Allison] > Argh! Right you are -- the damn'd gratutious Microscoft change to the > directory delimiter. I don't do Windows in general--and when > I do I use > r'c:\this\is\a\test' which does the right thing. Yes, that's what I do too. For those who are not that familiar with Python, the "r" prefix indicates that the string is "raw" - characters have their normal meaning, so that a backslash is not special. Using os.path.join would the preferred way to build up paths, except that it is restricted in Python Scripts. Cheers, Tom P

[ From: Michael] > When I try the following python script the message 'TypeError: > unsubscriptable object' appears. > > Python script > > container.manage_addProduct['LocalFS'].manage_addLocalFS('test > ','test','c:\temp\test3') Before anything else, you need to escape the backslashes - manage_addLocalFS('test','test','c:\\temp\\test3') Remember, you are writing a Python expression, and backslashes in strings need to be escaped.

[ Dennis Allison] > > Tom, I don't think the backslashes need to be escaped here. > Really? I've never had occasion to try it ... so I just did. Here is the Python script - str = 'c:\this\is\a\test' return str When called via dtml-var, each character after a backslash was missing or otherwised changed. I had to double the backslashes to get the string returned correctly. Cheers, Tom P

comparing strings
by Katie Legere 17 Oct '03

17 Oct '03

I'm was calling a python method from my dtml method and passing it 2 strings which I would like to compare for equality (are they the same string) but I have 2 questions .. Can I do this in dtml without calling the script? I've tried: <dtml-if expr="REQUEST.has_key(link_url) and link_url==remove_link_url"> equal <dtml-else> not </dtml-if> If I call a python script to do this, how do I complare strings in Python? I tried passing the 2 strings and using strcmp(link_url,remove_link_url) but that doesn't seem to do it either. Katie Legere Kingston Frontenac Public Library
