When should I use one, when should I use the other, etc? That is basically the difference. Some commands will work a bit differently, since DTML within a Document is acting on the Document itself and DTML within the Method acts on the Method's container (ie Folder, etc.) I generally just use Documents in times when I want the Document to have properties of its own.

If you end up using Apache, which you might since you want to do virtual hosting, you can continue doing this as you do now and just set up a RewriteRule so that the mail list archive path is served up as standard HTML. If you do really want it in Zope, you could use XML-RPC or ZClient to update things via cron. >What sort of logs does the Zope server produce?

Another Question
by John Goerzen 03 Sep '99

03 Sep '99

OK, another newbie question. I have searched through the documentation but can't find any help... I want to have a list of upcoming (or even previous) events. Each item in this list should have a date, a title, a URL for more information, and a description. In the OO form of thinking, there should be an Events object, and if I were in a C or Perl mindset, I would think of an array of Events objects. How can I do this in Zope? I'd like to, for instance, have an Events page that can display details about all the upcoming events. Or, a quick summary to put on a main page that would display only the title and use the URL as a link. I thought about putting a bunch of separate documents in a folder, but -- I can't access that from its siblings. Ie, if I have a folder named ACLUG/Events, I can't access it from ACLUG/Info (apparently?). Also, I'd have to know all the names. And, that still doesn't let me write some quick script to go through there and pick out only upcoming events or some such thing. Is a Gadfly thing useful here? I couldn't find a reference on that either (just a brief tutorial).

Many Zope questions
by John Goerzen 03 Sep '99

03 Sep '99

Hi, I'm just new to Zope, and have some questions both on documentation and on overall architecture. First, despite reading the descriptions in the documentation, I still don't understand the difference between a DTML Method and a DTML Document, save that documents (apparently?) have their own properties (variables?) When should I use one, when should I use the other, etc? Next question. I'm wanting to take a site, say http://www.aclug.org/ that I currently maintain with a set of m4 macros, and put it into Zope. I'd like to do nice dynamic things like, say, have a Quick Links bar that is defined somewhere. This could then be turned on or off by the user (probably by saving a cookie). Also, maybe I'd like to use this Quick Links bar in other documents. First, I suspect that I should then make an object with the Quick Links bar. How do I import that object into documents later? There was a reference in the DTML manual to an addDocument function, but I can't find any information on that function. Also, how do I go about doing the dynamic inclusion and cookie settings? Specifically, how do I make a "click here to remove" thing that will set a cookie saying to not display that particular part? How do I do virtual hosting with Zope? For instance, let's say I have 5 websites, each with different domain names, but hosted on the same machine. Right now, I've got Zope's special server going (not using the Apache tie-in). Do I need to use the Apache tie-in, and if so, does this have a negative impact on performance? There are some things that just cannot easily be put into Zope. For instance, I have software that creates a HTML tree for mailing list archives, and updates the tree each night. With Apache, I just set an Alias so that these items can be easily seen. How can I do this with Zope? Is it even possible? What sort of logs does the Zope server produce? Can they be formatted to be like Apache's so standard web log analyzer software can parse them? Thanks! -- John Goerzen

Installing ZODBC DA 3.01.b
by Thomas Weiner 03 Sep '99

03 Sep '99

Hi all, I've got problems installing Z ODBC DA 3.01.b. Though the Zodbcda folder shows up correctly in the lib/python/products directory of my (2.0.0) installation, the Z ODBC database connection doesn't appear in the list of the available objects after restarting ZOPE. Did anybody else run into this? Regards, thomas -- fon: ++49 (0)40 42878 3781 fax: ++49 (0)40 42878 2728

Real Soon Now (sigh) Z Discussions[1] will appear on Zope.org beta. It is a fairly simple but powerful app, done completely with Z Classes (no python), just drenched with comments from one end to the other. It demonstrates solutions to a number of common beginner problems with both Z Catalog and Z Classes. Watch for it to appear on a web browser in your home town! Mike.

DC's ZSybaseDA 1.0.1 - (location revealed) Does it leak memory ?
by Dr. Ross Lazarus 03 Sep '99

03 Sep '99

I've been wondering about our python processes slowly bloating out - we use dc's ZSybaseDA v 1.0.1 which is hidden on the main zope site at http://www.zope.org/Download/ZSybaseDA. Any other ZSybaseDA users out there seeing this ?

So far this is just a theory.

Some ideas for ZCatalog and XMLDocument
by Jason Jones 03 Sep '99

03 Sep '99

I've been using ZCatalog and XMLDocument for a bit now and am really impressed. These are fantastic tools. Seeing as how they're pretty early in their development though, I couldn't resist the urge to comment on some ideas for the future. 1. ZCatalog should be able to index objects according to user defined criteria (such as indexing on anchors in text, on in-text meta-data, etc...) so that matched positions can be specifically targeted. 2. ZCatalog should be able to return text hits in a user defined context, the easy way would be to have this context determined by the method 1. For instance if my boundary is anchor based, then context could be all text corresponding to that anchor chunk. 3. XML should be a built in system type, not confined to an XMLDocument. My thinking is that it would be great if I could register a DTD (or Schema) with zope, and then do something like <dtml-var text_content fmt="XML:my"> where "my" is a registered DTD, and then use dtml based render methods, or an associated XSL stylesheet to format my output. 4. ZCatalog should be integrated with the above XSL services. When you register a dtd or schema with zope, you should then be able to set up indexes on elements and attributes of that schema (just like you do on properties of regular objects). ZCatalog could then be used as an XQL engine as well. Ultimately it would be great to do something like this: registered dtd: <!DOCTYPE EXAMPLE [ <!ELEMENT article (title, author, abstract, body, discussion, references)> <!ELEMENT title (#PCDATA)> <!ELEMENT author (#PCDATA)> <!ELEMENT abstract (#PCDATA, ital, bold)> <!ELEMENT body (#PCDATA, p, ital, bold, head1, head2, head3, math, image, list)> ..... etc ..... ]> Along with the dtd, I would register any number of XSLT documents or render methods for example: "formatHTML_xsl" And I would index elements in the ZCatalog: title, author, abstract, body, etc... Then, with the following XMLDocument text: <?XML version="1.0" encoding="UTF-8"?> <article> <title>Example Article</title> <author>Me</author> <abstract>This is <ital>abstract</ital> text</abstract> <body> <head1>This is <ital>body</ital> text</head1> <p>This is some general <bold>paragraph</bold> text.</p> ..... etc ..... </article> I could do something like: <dtml-in "catalog.searchResults(meta_type='EXAMPLE')"--> <a href="/<dtml-var "catalog.getpath(data_record_id_)">"><dtml-var title></a> <dtml-var abstract fmt="XML:EXAMPLE" render="formatHTML_xsl"> <hr> </dtml-in> To return a nicely formatted abstract and link to the full XML article, which could then be rendered to down like: <dtml-var article fmt="XML:EXAMPLE" render="formatHTML_xsl"> or if I had another XSLT document called "formatPDA_xsl" then: <dtml-var article fmt="XML:EXAMPLE" render="formatPDA_xsl"> I left off .dtd and .xsl because they'll be zope objects not file references. etc... Of course, folding in items 1 and 2 with the above, then I could search on "body" for instance, return a context chunk from indexed <p id=#> tags for instance, and then jump to the appropriate paragraph section in my body text in my formatted XMLDocument. Also, I could identify any random block of text (in a DTML Document for example) as an XML fragment corresponding to a certain DTD and have it automatically rendered by the appropriate method or stylesheet. Anyway, just some ideas and wishful thinking for the future. Jason jason_j(a)countermedia.org
