Detecting acl username
by Michael Fox 27 Sep '99

27 Sep '99

Hi, Is it possible to output a username once a acl user has logged in? Example - If my login is Bill, once I enter the secure area of the site, it could say - Hi Bill Thanks in advance, Michael.

Re: [Zope] A cute traceback

Hi, I've usually seen this one when Zope can't quite determine the content type. Assuming interview_edit is supposed to spit out HTML, you can probably fix this by adding this line to the beginning: <dtml-call "RESPONSE.setHeader('content-type', 'text/html')"> Kevin -----Original Message----- From: Morten W. Petersen <mpeters(a)online.no> To: zope(a)zope.org <zope(a)zope.org> Date: Sunday, September 26, 1999 11:51 AM Subject: [Zope] A cute traceback >Here's a strange one. > >

Using colon and type identifiers in names with javascript
by Jim Sanford 26 Sep '99

26 Sep '99

I like the ability to type a variable for zope by using the vname:string syntax. However, javascript does appear to like variable names with embedded colons. My site is an inhouse site for access to company customer and order data. Our html forms make extensive use of javascript for validation and on form lookups and therefore I have not been able to use the colon+type feature in my variable names. Is there an alternate? Could I suggest something like vname__zpstring systax? Does anyone have any idea what module(s) would I need to patch to make this work? I would think that something that takes the request data as it comes in and translates __zp in any passed variables to a colon would work. Any suggestions? __________________________________________________________________ Jim Sanford ^ Database Engineer ^ ^ ^ Accelerated Technology, Inc. ^ ^ 720 Oak Circle Drive East ^ ^ ^ Mobile, AL 36609 ^ ^ ^ Voice: 334-661-5770 fax: 334-661-5788 ^ ^ E-Mail: jsanford(a)atinucleus.com Web: http://www.atinucleus.com Source Code, No Royalties, Any CPU...It just make sense ! __________________________________________________________________

A cute traceback
by Morten W. Petersen 26 Sep '99

26 Sep '99

Here's a strange one.  I keep getting this at what seems to be random intervals; I've reinstalled Zope once to get rid of this message, but, it seems to be something wrong with what I've created. Any ideas?

finding out names of properties
by Martin Dougiamas 26 Sep '99

26 Sep '99

I'm getting a single record back from a ZSQL method, which may consist of a variable number of fields. The following snippet prints out the contents of all the fields: <dtml-in getrecord> <dtml-in sequence-item > <P><dtml-var sequence-item> </dtml-in--> </dtml-in> but I also need to know the NAME of each field - how can I do this? (the docs seem to indicate it would be sequence-key, but it isn't ...) ... Cheers, Martin -- ### Martin Dougiamas ### http://dougiamas.com/

DTML query

Is there any reason why DMTL docs cant be translated and compiled into .pyc files? Would eliminating an interpreter layer result in a performance increase?

How to import SGML (like XML) and catalog it
by Avus 26 Sep '99

26 Sep '99

HI, Has anybody already implemented a way to import SGML files (linuxdoc or DocBook DTD), and catalog it in ZCatalog. Given the similarity to XML, the XML products could maybe be used. Another thing: Are there examples of how to use catalog.py outside of Zope. Has anybody done that already? Thanks Avus ____________________________________________________________________ Get your own FREE, personal Netscape WebMail account today at http://webmail.netscape.com.

Question about Python Methods Product
by David C. Morrill 26 Sep '99

26 Sep '99

I just finished downloading the Python Methods Product tarball, and after playing around with it for a while, I am totally confused. I'm hoping someone can help straighten me out... Are the Python Methods you create supposed to be methods or functions? For example, if I enter: Parameter list: self Body: return self.id I get the error message: Error Type: TypeError Error Value: len() of unsized object If I change the parameter list to: 'self,a=1' the method is defined successully (note that 'self,a' gets the same error as above). If I then click on 'TryIt', I get the name of the folder containing the Python Method (as I was hoping). Now, if I use <dtml-var myMethod> in a DTML method, I get the same result as 'TryIt'. But if I use <dtml-var "myMethod('xxx')">, I get the error: Error Type: AttributeError Error Value: 'string' object has no attribute 'id' which makes sense if it is a function, since 'xxx' gets bound to 'self' instead of 'a'. But then why does it work like a method when no args are passed? I just noticed that <dtml-var "myMethod(a='xxx')"> seems to work correctly. I'm not really a Zope or Python expert, so I don't know if I'm dealing with a bug or a problem in my understanding. Any help explaining these phenomena will be appreciated. Also, it would be nice if the 'TryIt' tab allowed you to enter arguments, like a Z SQL Method does. It would really help trying out methods which take arguments, without having to write a DTML method/document first. Just a future wish list item :-) Dave Morrill

re: Meta headers
by Chris McDonough 25 Sep '99

Jonathon, I'm not sure I understand the question entirely, but couldn't you just make a DTML method called "meta_header_global" in the root of the object database which contains:  <LINK REL = "Home" HREF = "http://www.stamp-coin.com/index.html" TITLE = "Stamp And Coin Shop Main Page"> <LINK REL = "Index" HREF = "http://www.stamp-coin.com/sitemap.html" TITLE = "Stamp And Coin Shop Site Map"> <LINK REL = "Toc" HREF = "http://www.stamp-coin.com/links/index.html" TITLE = "Stamp And Coin Shop Site Index"> <LINK REL = "Help" HREF = "http://www.stamp-coin.com/links/help.html" TITLE = "The Stamp And Coin Shop Web Site Navigation Help Page"> <LINK REL = "Copyright" HREF = "http://www.stamp-coin.com/links/copyright.html" TITLE = "Stamp And Coin Shop Copyright Page"> <LINK REL = "Glossary" HREF = "http://www.stamp-coin.com/links/abreviation.html" TITLE = "A Philatelic Glossary"> <LINK REL = "Stylesheet" HREF = "http://www.stamp-coin.com/common/default.css" TYPE = "text/css"> <LINK REL = SCHEMA.VW96 HREF="http://vancouver-webpages.com/VWbot/VW96-schema.html"> <META NAME = "author" CONTENT = "Jonathon Blake" > <META NAME = "Generator" CONTENT = "Massage.py Version 1.0.15.1"> <META NAME = "VW96.objecttype" CONTENT = "Catalog"> <META NAME = "Robots" CONTENT = "All"> <LINK REV = "Made" HREF = "mailto:jblake@stamp-coin.com"> <META HTTP-EQUIV = "distribution" CONTENT = "global" > <META HTTP-EQUIV = "reply-to" CONTENT = "jblake(a)stamp-coin.com" > <META HTTP-EQUIV = "Resource-Type" CONTENT = "catalog" > <META HTTP-EQUIV = "Content-Style-Type" CONTENT = "text/css" > <META HTTP-EQUIV = "Content-Script-Type" CONTENT = "text/javascript" > <META HTTP-EQUIV = "Content-language" CONTENT = "en-US" > <META HTTP-EQUIV = "Copyright" CONTENT = "John Konrad / The Stamp And Coin Shop 1999" > <META NAME = "Rating" CONTENT = "General"> <META http-equiv="PICS-Label" content='(PICS-1.1 "http://www.adequate.com/ratings/" l gen true comment "ADEQUATE.com" for "http://www.stamp-coin.com/index.html" r (WEB 2 v 0 s 0 l 0 d 0))'> <META http-equiv="PICS-Label" content='(PICS-1.1 "http://www.rsac.org/ratingsv01.html" l gen true comment "RSACi North America Server" by "jblake(a)stamp-coin.com" for "http://stamp-coin.com" on "1999.06.21T17:51-0800" r (n 0 s 0 v 0 l 0))'> <META http-equiv="PICS-Label" content='(PICS-1.1 "http://vancouver-webpages.com/VWP1.0/" l gen true comment "VWP1.0" by "jblake(a)stamp-coin.com" on "1999.06.21T15:21-0700" for "http://www.stamp-coin.com" r (MC 0 Gam -1 Com 3 SF 0 Edu -1 S 0 Can 0 V 0 Env 0 P 0 Tol 0 ))'> <META http-equiv="PICS-Label" content='(PICS-1.1 "http://www.weburbia.com/safe/ratings.htm" l r (s 0))'> <META http-equiv="PICS-Label" content='(PICS-1.1 "http://www.classify.org/safesurf/" l gen true for "http://www.stamp-coin.com/" r (SS~~000 1))'> Then for each different section in your site that requires section-specific meta-headers, create a "meta_header_local" DTML method in that folder.

Z SQL question..
by Francisco Sam Castillo 25 Sep '99

25 Sep '99

Hello, I have huge problem here, mainly because of my lack of knowledge and understanding of Z SQL methods, I really need some help, and I am hopeing some one would be willing to give me some light on the following issue: I have succeded in creating a dtml form and sql method base on the marvelous how-to recently posted on the subject, but I have different needs, I have created a Mysql database that serves to generate users accounts, and collects many info from them, the problem here is that I made the database with two indexes one with the auto-increment feature (no problem here) and a second one the email field that I have instuct mysql should be unique too, and thus when a user gets created if the email address exists, mysql won't allow insertion of new data base on the previous rule which is exactly what I want it to do, my problem is that I need to test this condition before so that if the email exists then the user gets a message telling her/him that either she/he most choose another email address, to avoid the error screen, or edit his current record which would need a some sort of validation as being the rightfull owner of the afore mention account. I know this might be to much to as of you all, but I am really stuck I have try many approaches unseccesfully and thats why I ask of you to help me if you will... Thanks a lot in advanced... Sam
