PSFS or DTML
by Stephane Tallard 12 Mar '99

12 Mar '99

Hi all , We try to use DocumentTemplate not for HTML dynamic generation but for C++ generation. For convenience, and because we are familiar with Python we intend to use the Alternate Python String Format Syntax. The generation code is beautiful compared to our previous output.write("blah blah.... ") instructions. Reading the docs, looking at the Zope site, this behaviour doesn't seem to be shared by a lot of zope users. Moreover the Alternate Python String Format Syntax is poorly documented, and DTML features seems to be usable but the way they can be used seem very strange. Basically our needs are to use conditional structures, iterative structures and to call methods. The last point seems to be the hardest one. The following code shows a way to call python methods in python strings but 3 persons during half a day have been necessary to find it out. I suppose you can imagine my questions : Is there a natural and convenient way to find out PSFS expressions going from their DTML equivalent ? Is there a complete documentation on PSFS syntax ? Are the features of DTML and PSFS identical ? And the most important : Do you encourage us to keep on using PSFS instead of DTML ? Thank for your help Stephane my code ================================= import DocumentTemplate ########################################## class attr: def __init__(self,att): self.att = att def get_att(self): return self.att def get_num(self): return len(self.att) ########################################## l__list = [attr('aa'),attr('bb'),attr('cc')] l_str = DocumentTemplate.String(""" %(l_item fmt=get_att)s %(l_item fmt=get_num)3d %(in l_list)[ POUETPOUET %(sequence-var-get_att)s %(in)] """) dict = {'l_item':l__list[1], 'l_list':l__list} print l_str(None,dict)

ANNOUNCE: Advanced DTML HowTo
by Amos Latteier 12 Mar '99

12 Mar '99

Hello Zopesters: Are you confused by the subtleties of DTML? Want the skinny on advanced DTML tricks and gotchas? Check out my advanced DTML HowTo: http://www.zope.org/Documentation/HowTo/DTML This document explains in detail the concepts behind advanced DTML tricks like indirect variable lookup, setting variables, calling sub-templates with different client objects, etc. Its main emphasis is on understanding how DTML uses a namespace stack to manage variable lookups. Enjoy and send me your feedback. -Amos P.S. Probably at least some of this material will be incorporated into the DTML User's Guide in the future.

access content informations & use mailhost services properties
by Service Informatique CHSR 12 Mar '99

12 Mar '99

Hello, Correct me if i'm wrong: one has got to have "access content informations" permission to be able to write:  right? I've been bitten with that, and once i gave "access content informations" to the Anonymous User, my problem went away. Also, before I submit this to the Collector, is it normal that the "use mailhost services" doesn't appear in the security tab of the folders? Each product has its permissions that are listed, but nothing with the mailhost object. I had to change it directly in the mailhost object. If it's normal, it means that i can't give global permission for mailhost objects??? What confuse me, however, is that the mailhost object claims to "acquire" permission settings from its parents, but nowhere in its parents i can define the permissions. Regards, Jephte CLAIN Service Informatique CHSR

I had the same problem. The rewrite rules put a the top of the file have no effect because they occur *before* mod_rewrite is activated. I had to put the rewrite rules a the end of the file. I works now. I don't know if this will solve your problem, but, just in case... Regards, Jephte CLAIN Service Informatique CHSR

Guestbook
by David Ascher 12 Mar '99

12 Mar '99

The guestbook product is broken in 1.10.2. I've 'fixed' it by removing both references to OFS.DocumentHandler (import and class inheritance). Now it's not broken, but it doesn't seem to work! Anytime I enter any data, it says 'data entered' but nothing ever shows up in the data view. Has anyone fixed this? BTW, I couldn't find an author name listed anywhere. --david

Lots of questions:
by andreww＠netscape.com 12 Mar '99

12 Mar '99

1) How do I get Zope to run as a service on my NT box so I dont have to stay logged in for it to run? 2) When I upgrad Zope will I have to re-build all of my applications? 3) Is there an IRC channel for ZOPE? IF not I would like to offer the idea of creating one on say the mozilla or slashdot servers 4) Is there anyone interested in working with me on a Zope/Dreamweaver cross-communication project? -- ------------------------------------------------------------------------- - Andrew Wooldridge - Opinions expressed are my own - - andreww(a)netscape.com - http://people.netscape.com/andreww/ - ICQ: 6345881 - Find It at http://dmoz.org - -------------------------------------------------------------------------

Newbie questions.
by Craig H. Rowland 12 Mar '99

12 Mar '99

Hello, I've looked through all the docs, FAQs and threads of the Zope list for some of these answers and haven't found a clear method described. I'll apologize now if the questions seem obvious, but I'm new to deploying Zope on a web server and need some initial Zope setup guidance. Question 1: Under Zope, what is the proper way to configure the website so users can simply go to http://www.example.com instead of: http://www.example.com/example http://www.example.com:9673/ etc. My understanding is that the mod_rewrite rules will have to come into effect here. Will I also need to do a re-direct of some type? I need some way to direct all URL requests so they are re-written to point to the correct Zope folder. The ideal for me is to have a series of folders in Zope that contain separate websites. The sites can be virtual hosted as needed (although right now I'm only running one site). I can't find a clear description of how to make this happen. Also I don't want to run a separate Zope process and proxy people to the port. I want to have everything running on port 80. I'll have to agree with other posters that a tutorial on the design of the actual Zope site with Zope would be very helpful as they are using a layout of html and hierarchy that is very similar to what I'm pursuing. In fact if someone could provide me with a description of the config they're using it would be a huge help. Question 2: Under .DTML construction of links is it generally considered "better" Zope practice to reference the entire URL or the Zope object hierarchy directly? Question 3: I don't want tracebacks to appear under any circumstances to the end users. I haven't tried anything to counter this yet, but wanted to know what some others have done. Would an approach to this be a try/except positioned in the standard_html_header and footer files? Ideally I would like to catch all exceptions and have it automatically mail the exceptions to the webmaster instead of showing the user (In fact I think this would be a good feature for the product). Question 4: Has anyone pursued a security audit of the Zope code? I've been considering doing this (not that I don't trust the Zope developers, it's just that I don't trust anyone) and would like to work with others if possible. Several of the sites I admin get hacked on very frequently and I'm a little nervous about replacing static web pages with no CGI running anywhere with the exact opposite end of the spectrum with Zope. :) I'm also going to prepare a document describing how to run Zope in a chroot() environment under UNIX to increase security. I'll let the list know when it is complete. Thank you for any responses, -- Craig

Zope Benchmarks and Performance testing
by Geoff Deering 11 Mar '99

11 Mar '99

I'm new to this list. It seems to me that the www.zope.org is rather slow this week. Documents are taking far too long to be parsed. Pings seem reasonable, so I am expecting that the server may be receiving a lot of requests and being overloaded (maybe from the Web Review article). So I am just wondering what the specs of the system that the www.zope.org ISP is using. Also wondering about stress tests and benchmarks for the Zope system. (It must also depend on backend systems etc) Geoff Deering Web Programmer Charles Sturt University
