What is the correct syntax for passing form data to child frames of a frameset ? I would like to pass form fields that is submitted to frameset to child frames. Is there any alternative built-in syntax to using an ugly construct like this : =& ------------------ Hannu

- FYI: Zope Roadmap for next two months
by Paul Everitt 23 Jun '99

23 Jun '99

Howdy all. I've attached below a quick snapshot of things happening for Digital Creations and Zope. The roadmap finally allows me to answer some of the questions coming up here in the Zope community. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909 Zope Roadmap For about two months I have made attempts to write down a roadmap that described future directions for Zope. I could never find the right format for detailing the items, though. No one likes to go on record making promises. I settled on the following format as a good compromise that allows me plenty of wiggle room. Each of the items below has a number between one and three in front of it. A one means we are quite likely to do it in the next two months. A three means we have done some work on it and are likely to do more work on it, but don't expect too much progress. The easiest way to get us to change priorities, of course, is through consulting. Many of the items in the list are in support of existing consulting projects. I'll start with Digital Creations, as some of the items we are looking at impact the Zope community. o (1) Hire seven more folks. I expect us to have concluded employment contracts with another seven people by the end of February 1999. We are pretty busy on consulting contracts right now and, as you can see, have quite a backlog of Zope work to do. o (1) Get ten case studies online. Just about everybody new to Zope and/or Python wants to see something done with it. We *have* done interesting work, we just need to package it up to make the case studies and testimonials visible. By the way, giving us some good words to put on the website about Zope really, really helps us convince newcomers to try it out, so pitch in! o (1) Relocate offices. By the end of January we will have switched offices as we need a lot more space. Needless to say we have a disruption facing us but we are doing a good job of managing it so far. o (1) Business plan for 1999. There are a couple of trends that are emerging on the scene in 1999, most notably the mainstreaming of open source. We would like to position ourselves to capitalize on these trends. Thus we are reviewing our business plan and having a board vote first week of February. o (1) Start a Zope Hosting Provider program. I have a page mostly finished for a signup and have two companies that have indicated serious interest. The following is a list of initiatives in the Zope area that are on our radar, though some rely on continued funding from consulting projects, which can be tough to predict: o (1) Tabula and indexing structures. We are going to begin a slow process of moving pieces of Tabula into Zope. The Zope 1.10 release will put the BTrees, integer sets, and indexing machinery into Zope. Tabula itself will be available just afterwards for a small audience of those willing to work with us on it. Over time this will mean Zope will scale up much, much more. In the nearterm it allows the Zopespot project to get kicked off. o (1) Start Zopespot. We have been planting seeds for a while to do a "Slashdot" in Zope. I have been working on a requirements document off-and-on for the last two weeks. More importantly, Ken Manheimer was hired to be the shepherd for this project. More to follow in a separate post. o (1) Release overhauled versions of the four main documentation artifacts. We hope to have by the end of this week new, overhauled versions of the Zope Manager's Guide, the DTML guide, and the SQL Methods (formerly Aqueduct) guide. When Tabula makes it out we will publish its documentation. o (1) Zope 1.10 released. Zope 1.10 will include: - BTrees and integer sets - The SearchIndex package which has a number of indexing classes, including classes for field indexes and text indexes. - Property management broken out into a separate mixin - Properties DTML Documents, Images, and Files - Image patches provided by Ty Syrna to allow size attributes - New absolute URL feature to allow images to referred to from different folders more easily - Bug fixes, plus anything else I've forgotten o (1) Relocate zope.org. Starting this week we are relocating the website which has a big fat pipe to the Internet, as well as people more talented than us to look at it. We'll make a separate announcement about this. o (1) Public CVS server. When Ken gets here I imagine he'll move pretty quickly to getting a public repository available using CVS or Perforce. o (2) Confera released. When the machinery from Tabula goes back into Zope we can brush up Confera and release it. Confera provides threaded discussions that include moderation, full-text searching, and more. Documentation was also written for it so we'll brush that off as well. o (1) WebDAV. Brian Lloyd has made quite a bit of progress on WebDAV. Our goal is to get Zope's hat in the ring for WebDAV as soon as realistically possible. o (1) Zope/Medusa with FTP. As you may have seen on Friday, Amos and Jim have worked with Sam to iron out an architecture document for Zope/Medusa. We should have an alpha release this month of Zope/Medusa with PCGI, HTTP, and FTP implemented as Medusa handlers. o (2) A formal Zope query language. Adding a standard query language, such as OQL or XQL, has recently become pretty important. I hope that we will show some progress on this over the next month or two. o (2) Zope2 beta with full concurrency. It is very important that we make progress on the architecture described by Jim's "BoboPOS3alpha1" paper. o (2) XML. Zope is a great fit for XML, even better with the machinery from Tabula going in. We also see XML becoming the basis for other initiatives, such as WebDAV and RDF. However, we just can't squeeze out the time to dive in deep. Rather, we'd love to see more community progress like that which popped up this weekend. o (3) Offer Collector. A good number of people have asked about contracting with us to get the Collector software for tracking bugs reports, feature requests, and more. Thus we might have a Zope-based solution available and packaged that our customers can drop into their sites. o (3) Replication. Being able to copy the contents of a main site to a local site, make changes while offline, then replicate them back up is a compelling opportunity for Zope. And it isn't that unrealistic, as some of the machinery is there already in the undocumented manage_exportHack operation. However, until it pops up on a consulting gig I doubt Digital Creations will return to it. o (3) Progress on "Python Interfaces", http://www.foretec.com/python/workshops/1998-11/dd-fulton-sum.html. Many of the initiatives we start around here seem to cross territory where we wish we had interfaces. Of course I might have forgotten a thing or two here or there. I'm sure you folks will let me know if I have. :^)

Re: [Zope] - XML-style DTML code

The fix > I proposed fixes that. Once I have a proper XML editor with full XSL > support, it'll be easier to hypothesise about solutions, but until then, > it's all hand waving. The editing-in-HTML-editors will always be a problem with the current syntax, in my opinion, because (real code here, and code i'm not at all ashamed to have written): <TD><SELECT NAME="category">  <OPTION VALUE="" SELECTED ></OPTION>  </SELECT></TD> will give just about any editor a headache. Cyberstudio, at a minimum, moves the comment tags outside of the <SELECT> statements. Dreamweaver might handle this a little better, but as you drag and drop the visual representation around it tends to get out of sync. This same problem hangs around ASP code with only one real visual editor existing (Drumbeat) - and most drumbeat generated sites I've been too have been as much fun as a root canal in slow motion. Since ColdFusion uses 'regular' tags, it's relatively easy to extend editors to handle them, albeit it usually in a limited fashion. And WebObjects, which introduces only one special tag into the HTML environment, requires another parser to handled the accompanying .wod file to be visual (.wod being full of statements similar to HTMLGen instances.) I don't even know what else is out there. I think Vignette's StoryServer can be used with DreamWeaver in the initial stages of design, but once StoryServers code starts getting into the HTML code they advise not going visual anymore (i think StoryServer uses *twitch* TCL in their pages). In any case, this is a very meaty problem - and not just for Zope.

ZServerFTP
by Robin Dunn 04 Mar '99

04 Mar '99

HomeSite's FTP mode is apparently trying to use the FTP commands "MODE S" and "STRU F" to which ZServer is responding with a "500 '%s': command not understood." % command and then HomeSite bails out and never fetches any directory listings or anything. Is there any intent to support these commands? It sure would be nice. -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!

Indirect variable references
by Timothy Grant 04 Mar '99

04 Mar '99

Hi, I'm going to try this one again with--hopefully--a little more clarity on my part. I am working on a Zope application that builds a page based on the contents of two Tiny Tables The first table provides categories, and the second provides detail for each category. DTML works beautifully to allow me to build the page. The code is as follows:  <tr> <td> <B></B> </td> <td> <select name="" size=1>  <option>   </select> </td> <td> </td> </tr>  As you can see the code builds a number of select boxes that are named with the names that are contained in the first Tiny Table. After the form has been submitted, I need a way of accessing the contents of those select variable names, and I cannot figure out how to do it. e.g., if the Tiny Table contains Fred, Ethel, Ricky and Lucy, I will get four select boxes named Fred, Ethel, Ricky and Lucy. It works fabulously, even though I knew it should work, I was still pumped when I looked at the HTML and saw what a nice job had been done. So after submission, Fred, Ethel, Ricky and Lucy all contain the value of what was selected. How do I programatically or should that be DTMLmatically access those values from within another #in construct? Thanks for any assistance. -- Stand Fast, tjg. =================================== Timothy J.

External / Internal Methods
by Christopher G. Petrilli 01 Mar '99

01 Mar '99

I vaguely recall this being discussed in the past, but I can't find it in my archives... Has anyone tried to make a comparable thing to an "External Method" but that is contained in the database itself? The reason is this... we've set up Zope on the Starship, and some people would like to experiment with ExternalMethods, BUT... that requires access on the file system to stuff that we'd rather not open up, or a hueg amount of administrative overhead. Ideas? Chris -- | Christopher Petrilli ``Television is bubble-gum for | petrilli(a)amber.org the mind.''-Frank Lloyd Wright
