Customizing Error pages?
by Alec Munro 09 Jan '04

09 Jan '04

In response to Paul Winkler (because I'm no good with mailing lists). I've tried modifying standard_error_message, and it seems like it works sometimes. My impression of it is that standard_error message picks up Zope Errors, but there is some other template somewhere which picks up Site Errors. Interestingly enough, the Site Errors template will attempt, to a degree, to make use of the standard_error_message. I guess I will do some searching and see if a solution to this pops up. Thanks, Alec

Hi all, I want to put a DTML page in a slot:main in a Plone site, but I don't know how to do it. Is there some method to put a DTML page into a ZPT one or some other way to do this. Thanks a lot, Gabriela _________________________________________________________________ MSN Amor: busca tu ½ naranja http://latam.msn.com/amor/

Cookies
by Totty, Yvonne 09 Jan '04

09 Jan '04

Hi! I'm trying to use cookies via DTML. I need to get information from a cookie and send it to a Query. I find searching on the Zope site frustrating and cannot find any examples on how to GET information from a cookie. Basically, what I am trying to do is push the 'where' statement from one page to another, then to the query. First, is a cookie the best thing to use here? Second, should I use the request object to set the cookie, or can I do it the javascript way. If I need to use DTML, how do I do it? Third, how do I retrieve the information? Thanks in advance, -y ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Yvonne Totty

http://mail.zope.org/pipermail/zope-dev/2000-June/005565.html and http://www.zope.com/News/PressReleases/CMF1.0March01 CMF integrates with many standard tools, components and protocols, including XML, WebDAV, RPC, SOAP, and LDAP SOAP? where? Dec 1999: http://www.linuxjournal.com/article.php?sid=5126 Zope, one of the leading open-source application servers for content management and portals, will soon support two network protocols heavily supported by Microsoft, the Simple Object Access Protocol (SOAP) and the Web Distributed Authoring and Versioning (WebDAV) protocol SOAP?? where? we are in 2004 :-) :-) I need Soap in Zope, can someone help me? I'm still at python level, with a lot of problems with apache java maps :(

Learning Zope Page Templates
by Alex Newby 09 Jan '04

09 Jan '04

Hi, I've googled around a bit, but fallen a little short in finding some good information on learning ZPT. I'm new to Zope, and to programming, but know XHTML like the back of my hand and am becoming more experienced with CSS everyday. I come from MoveableType and quickly learned the syntax of it's templating language, to the point of frustration:), so ZPT doesn't seem off the mark; nevertheless, short of Appendix C in the Zope Book I've come across little to help me make the transition. I was wondering if anyone had any suggestions that aren't showing up in Google. For the obvious... I found this to be rather nice: http://www.zope.org/Wikis/DevSite/Projects/ZPT/SimpleTutorial The discussion of the "metal" here to be informative: http://www.zopemag.com/Issue003/Section_Articles/article_ZPTintro.html This is good too: http://zdp.zope.org/projects/zqr/ZopeQR And the prospect of using dtml to dynamically render my css is blowing my mind. I'm wondering if I can be directed to some of those resources off the beaten path. Appreciatively, Alex Newby http://zopista.com

Re: [Zope] Navigation menu
by Michael Havard 08 Jan '04

Thanks for the prompt response. Unfortunately I don't think that will work. I think the problem is that the code I've seen essentially just counts how far down a tree an item is (link depth) and the spits out either a text-indent or a number of cells based on the link depth. That means that the code has no concept of there being a relationship between the current item it's calculating link depth for and the previous parent element. For instance in your code I see a parent entry like Collections & Resources with a child of: Archives & Special Collections with a child of: Aids History Project I can SEE that hierarchy only because of the visual formatting method used: ROW Collections & Resources ROW Table CELL - Archives & Special Collections ROW Table CELL - Table CELL - Aids History Project In that HTML structure there's nothing to logically tell me that any of the elements relate to each other in any way. According to the DOM the elements are not siblings or anything relatively meaningful. I need code that actually produces and structured HTML heirarchy not just the appearance of one. again something like <ul> <li>Item <ul> <li>Child Item</li> </ul> </li> </ul> Where the child node is actually nested into parent node structure. >From: Jason Randell <randell(a)library.ucsf.edu> >To: "Michael Havard" <nhavar(a)hotmail.com> >Subject: Re: [Zope] Navigation menu >Date: Thu, 08 Jan 2004 14:17:13 -0800 >MIME-Version: 1.0 >X-Sender: randell(a)Mail.library.ucsf.edu >Received: from gossamer.ckm.ucsf.edu ([128.218.33.11]) by >mc12-f16.hotmail.com with Microsoft SMTPSVC(5.0.2195.6824); Thu, 8 Jan 2004 >14:18:16 -0800 >Received: from maculosus.library.ucsf.edu (maculosus.library.ucsf.edu >[128.218.15.43])by gossamer.ckm.ucsf.edu (8.11.6-20030924/8.11.6) with >ESMTP id i08MIGW14005for <nhavar(a)hotmail.com>; Thu, 8 Jan 2004 14:18:16 >-0800 (PST) >X-Message-Info: JGTYoYF78jHfxfCqrpxphA9Flfi1HC0n >Message-Id: <5.1.1.5.2.20040108141610.00b0ecf0(a)Mail.library.ucsf.edu> >X-Mailer: QUALCOMM Windows Eudora Version 5.1.1 >In-Reply-To: <Law9-F24U135TcfM6LK00011412(a)hotmail.com> >X-Filter-Version: 1.7 (gossamer) >Return-Path: randell(a)library.ucsf.edu >X-OriginalArrivalTime: 08 Jan 2004 22:18:16.0294 (UTC) >FILETIME=[50286060:01C3D635] > >Michael, > >I use an expandable/collapsable tree format on my site... > >http://www.library.ucsf.edu/sitemap.html > >take a look at that and see if it is something you could work with. > >Cheers, >Jason Randell > >At 10:06 PM 1/8/2004 +0000, you wrote: >>I've been looking for a navigation menu/sitemap for ZOPE.

Re: [Zope] Scrolling Tables
by Alex Newby 08 Jan '04

08 Jan '04

There are some situations when it is vitally necessary to use javascript. The most obvious being if you have images that you wish to be displayed only on a particularly sized viewport. i.e. 300px width image for 800*600 and 500px for 1024*768. For CSS, etc, javascript is a little heavy, and might not even be available if its turned off. Tim Zegir said: "Sorry if some one has pointed this out already, but why can't you just create your base table with you heading etc and in the field you want to scroll content create another table (border="0" :) ) and scroll that???" This makes more sense, but why do it all in tables?? Judging by the responses thus far it would be possible to simply wrap a div around your column headings This would not be valid xhtml strict, but you might be able to pass it off as xhtml transitional. I haven't given this a go because I lost the link to that nice css frame hack. <div style="wherever_that_wonderful-link_to_pure_css_frame_went:("> <table cellspacing="0" cellpadding="0" summary="My half-baked table"> <tr><td width=?">Header1</td><td width="?">Header2</td></tr> </div> <tr><td>Scrolling part</td></tr> </table> This is basically what Tim said. I'm sort of new to dtml and all, but if you're pulling the data dynamically from someplace it should be relatively trivial to build the table width when the table is constructed. <tr><td width="sub_routine_magic">Foo</td><td width="add_us_up_to_100%">Bar</td></tr> I believe that when it comes to HTML, everything works with Zope. Get everyone to use the same web-browser and you're fine:) Alex Newby zopista.com Jens Vagelpohl wrote: >To me that sounds like a pure HTML issue that has nothing to do >with Zope. It is an HTML issue but HTML doesn't have an easy way to do it. I hoped that there might be some sort of plug in that someone here had worked with. Something that could work with Zope. Dylan Reinhardt wrote: >You could hack this together using DHTML/JavaScript with frames. This is probably the best suggestion but it's beyond my current abilities. I didn't know that JavaScript could read the column headings. Does Jython allow you to do this kind of scripting using Python instead of Java? I'd rather not go back to a second language.

RE: [Zope] Weighing catalog searches per index ?
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 08 Jan '04

08 Jan '04

Casey, Thanks for pointing out this product, I'll have to give it a try, as I can foresee many useful applications for it ! I'm working on the next generation of our site. Currently we use a regular TextIndex, which is obviously oversimplistic and insufficient. So right now I've been using ZCTextIndex through development, and it seems to give decent results (Hard to tell without getting some mass usage). Problem is some co-workers using different technologies have "weighing" and it sounds like something interesting, at least form the user perspective. Notably, we'd like to maybe experiment with giving the Title more priority over the rest, so that when someone views the search results with the titles, it's perceived as being relevant results. Also, if we have weighing, content could possibly be tweaked/adjusted to take that into account (Notably with Keywords). Your product seems to have a good base to start with. The problem now, and one that stopped me in my tracks, is how to define/calculate/configure this "weighing" concept. You suggest there's some underlying functionality for weighing already, maybe it'd just be a matter of taking advantage of it, and documenting how to use it ? The big question would be what does a weight of "1" MEAN versus a weight of "2" or "5" ? The other is how it gets purely implemented. Does the weight need to be known at indexing time, or can it be provided at search time ? My hunch is the weighing should be applied at search time, so your product could be modified to take as input the weights to apply to each index that is being search through ? Something like: result = catalog(dc_fields={"query":"Some search string", "fields":["Title", "Description"]}) could become: result = catalog(dc_fields={"query":"Some search string", "fields":["Title", "Description"], "weights":[5,1]}) Meaning apply a weight of 5 to Title, and 1 to Description. Which I would in turn interpret as meaning Title is 5 times more important than Description (Not knowing any better right now). Personally I'm using the Okapi algorithm. When I started investigating this, I came to the (admitedly uneducated) conclusion that to do proper, fast weighing, then the Okapi implementation would have to be modified to support this feature (Maybe it does already ??), which is over my head, especially with the okascore module being Python/C. Doing it in python would mean doing a second pass over the results that have already been scored once, which is innefficient it seems, and computationally intensive (Especially as I envision th efact that really really nice weighing algorythms would need to have all content in memory in order to do relational work between records). Anyways, that's what I've been thinking about ... But the benefits of having such a beast seem really tentalizing, so I thought I'd ask anyways ... Besides maybe I'm way out to left field on this and it's easier than I make it out to be ?! :) Thoughts ?

Low-level support for this already exists via the weightedIntersection and weightedUnion set operations. ZCatalog currently gives all indexes a weight of 1 however. > I'd like to explore the possibility of searching the catalog, but > giving results from certain indexes priority over others. It is possible to implement an index whose results are scored. This is used by TextIndexes to implement relevance ranking for instance. The index just needs to return a mapping (usually a BTree) of rid->score where rid is the record id of the catalog record. ZCatalog automatically adds these scores when intersecting results across indexes. > So in the case of the CMF, saying that if search terms are found in > the Title or Descrption, they are more "important" than if they're > found somewhere else and so on ... This might be an iteresting addition to my FieldedTextIndex product. Currently all indexed fields are weighted the same, but it would be straightforward to make this configurable per field. > I know this is a common concept in more advanced search engines (Such > as Oracle's InterMedia), but I'm wondering if anyone has done > something like this in Zope ... Let me know what your specific use case is and maybe I'll add it to the FieldedTextIndex product if it fits its usage. -Casey

I dont' know if anyone has already suggested this, but have you considered using the CSS 'overflow:auto' attribute? I haven't tried it on a portion of a table but it couldn't hurt to try.. All you should need to do would be wrap a div tag around the portion of the table that you want to scroll. ... </tr> <div style="overflow:auto;" > <tr> Rows/cells that you want to scroll here </tr> </div> ...
