Partnership with B2B EMerging?
by Jonathan Desp 11 Sep '00

11 Sep '00

Hi guys or girls, I'd like to know if you are interested to partner with me, for the construction of B2B Emerging, at B2BEmerging.com. I would need someone technical, for Zope. I'm enthusiast and I put all my effort toward B2B Emerging. I invite you to read this site, it's a wonderful concept, with a marketing, a new marketplace. I have no limit, I think B2B Emerging could become the Amazon of the B2B. That's my goal. Of course it will be hard, that's why I wanted to create that project, but we learn when we have problems. I could do the site lonely, but to be alone, it's so hard. With someone to talk, it would be more interesting and more special. I want to partner with someone, I'm searching Mister B2B Emerging, a warrior, someone strong enough to understand that it could become the number one platform for businesses around the world. B2B Emerging is in the middle of Ventro and B Central. We could discuss about the partnership, I'm wide open. I want to change this world with this business, are you ready, I am. Very truly yours, <><><><><><><><><><><><><><><><><> Jonathan Desp Chairman and CEO, Atomasoft Inc. Matter will become software http://www.atomasoft.com/jonathan <><><><><><><><><><><><><><><><><>

Re: 2d list manipulation

OK, figured it out. About the only way I can see to do it in DTML is this: <dtml-call "col[index1].insert(index2, col[index1].pop(index2)+1)"> This command happens to increment the value at col[index1][index2], and this strategy allows any operation to be done on the value. It appears to be quite fast as well, so I'm content. --Tim

Creating a new Role equivalent to Manager?
by Kevin Howe 10 Sep '00

10 Sep '00

I want to create a Role (myRole) for an object which is equivalent to the Manager Role, basically kust with a different name. How do I (via python) say that myRole is equivalent? Something similar to this: self._addRole( 'myRole', InheritPermissionsFromManager() ) Thanks, kh

I'd imagine it would have something to do with PATH_INFO, PATH_TRANSLATED, or SCRIPT_NAME. Have you looked for calls to the Python cgi module in ZServer? I might start by looking for it trying to assign these environment variables to see what it does. Sorry I can't give you any more specifics.

OK, I think I understand... you need to keep using the servlets-style URL-rewriting because you serve Java applets that make use of sessionids, and you may want to serve these from Zope. I've done a little poking around in ZPublisher's HTTPRequest.py and BaseRequest.py and I don't think that's where the ';*' gets stripped. I can't find *where* it gets stripped. It must be possible to make Zope de-ignore things split on a ";", but right now I can't find out where to do so. > I had not decided if the user database exchange would be done by using > the client as a relay with user info emedded in > user,md5-password-signature components in the session id response > redirect or some Zope to JServ direct handshaking using > ZPatterns-based Membership.

Are they in an opaque format? Are they named with the sessionid?

RE: [Zope] Best way to handle SQL update with variable number of fields?
by Farrell, Troy 10 Sep '00

I'm trying to understand exactly what you mean. I have some ZSQL Methods that have an empty (INSERT INTO site_location VALUE('New York', '')) value in them. For the above I use: INSERT INTO site_location VALUE(<dtml-sqlvar site_city type=string>, <dtml-sqlvar site_zipcode type=int>). Can you provided your ZSQL Methods so we can understand better? Troy Farrell -----Original Message----- From: chris(a)ncafe.com To: zope(a)zope.org Sent: 9/10/00 4:33 AM Subject: [Zope] Best way to handle SQL update with variable number of fields? Hello, I'm creating a number of ZSQL methods to insert, update and delete records from several Oracle tables. Everything is working fine with the insert forms (creating new records) and the delete (of course). However, the best way to do the * update * without locking the user into a *very* rigid format is eluding me.. The problem - I would like to populate the form with the existing values and then allow the user to change the ones they want to. Some of the fields in the database are empty and it will always be that way. The length of the update statement will change. Nomatter how I do it, I am having problems with the commas. What is the best way to build the necessary logic into the form? Is there a sample in a product or a How-to somewhere that I can look at? I am assuming I need to create a list externally in a method and use that to determine the comma placement. Is that the "correct" direction? Or is there a better way.. Thank you, Chris Beaumont cbeaumon(a)msri.org

Albert, Hmmm.. can you take a step back and restate the problem more generally?

Emacs and dtml-mode +/-
by Nestor A. Diaz L. 10 Sep '00

10 Sep '00

HI, I have installed the dtml-mode that provided http://www.zope.org/Members/alburt under Debian potato, emacs20 and psgml it work so nice but i have a little question, and i don't know if it is possible to resolve, consider the following html code:  <html> <head> <title></title> </head> <body> <select>  <dtml-with>  </dtml-with> </select> <dtml-var> </body> </html> Check out that i can not insert a <option> tag inside the <dtml-with> tag, ok what i want to know (if there is any dtd guru here) is: there is posible to define a rule in this dtd to see that the <dtml-with> is inside a select and it shows as a correct element the <option> tag? I know it cat be done by using brutal force but i want to be "politically correct". Another question? Thats anybody know about a "html indenter" i mean something like the program indent avaialable under Linux ? for html? i know emacs indent but i have to press the <tab> on each line, or i'm missing some macro? It would be nice that this program can run under zope to show the html code generated beautifully for debug reasons, dont you think so? and desactivate it under a production environment. Well that's all folks, Bye, -- Nestor A. Diaz Ingeniero de Desarrollo Engendro - Comercio Electronico sobre Linux Email: nestor(a)engendro.com - WWW: http://www.engendro.com

Modification Posts to the list (was: [Zope] Import from file via management-interface)
by Dieter Maurer 10 Sep '00

10 Sep '00

Hi Tino (and other potential patch posters), if possibly, you should not post complete source modules to the list. Instead, you should use either context or uniform differences to the source. Such a difference file is called a patch. Patches have considerable advantages over the complete source: * they are much smaller * they can (usually) be applied to more than one version * they show directly what has been changed, this is essential for a decision whether or not to trust the changes. I will never install any source modules posted to the list. Usually, I will not even look at them. Patches can be created with the "diff" utility. This is a "standard" unix program (i.e. installed on any Unix system). There is an improved GNU version, which is also available for Win/32. There are other Windows implementations for "diff". Patches are applied with the "patch" utility. Again, there is a GNU version, and surely there are versions for Win/32. Dieter
