I hadn't anticipated Michel adding a link to the Product Developer's Guide project outline in the docs wiki into the Zope Weekly News this week (http://www.zope.org/Wikis/Docs/ProductDevelopersGuide) to all how-to writers, if you see your how-to referenced in there, it doesn't mean that we're just going to rip it off wholesale, we'll certainly ask your permission to use the content, and you'll be the decider. Tks! Chris McDonough Digital Creations Publishers of Zope - http://www.zope.org

A Description with a Search Engine using the advanced ZCatalog program ?
by Jonathan Desp 20 Jul '00

20 Jul '00

An accurate question here: I read the page: http://www.zope.org/Members/Zen/howto/AdvZCatalogSearching But I'm not able to understand very much, what is the section where they are talking about "a small description for every result" you are getting from the ZCatalog search engine ? My site is almost ready ! As well as my business plan for my company... Very truly yours, <><><><><><><><><><><><> Jonathan Desp Atomasoft Matter will become software http://www.atomasoft.com <><><><><><><><><><><><> "I used to think that the brain was the most wonderful organ in my body.

Reversing acquisition?
by zoper＠creative.isquare-asia.com 20 Jul '00

20 Jul '00

Hi All, Here's the situation I have a tree such that /index_html /text_object_1 /text_object_2 /subfolder/text_object_1 /subfolder/text_object_2 where content is: /index_html <dtml-var standard_html_header> <table> <tr><td><dtml-var text_object_1 fmt=structured-text></td></tr> <tr><td><dtml-var text_object_2 fmt=structured-text></td></tr> </table> <dtml-var standard_html_footer> /text_object_1 Just some text of text_object_1 /text_object_2 Just some text of text_object_1 /subfolder/text_object_1 Just some text which is different from /text_object_1 /subfolder/text_object_2 Just some text which is different from /text_object_2 The effect I would like to achieve is: when user access http://myserver/, content of /text_object_1 and /text_object_2 will be shown while user access http://myserver/subfolder/, content of /subfolder/text_object_1 and /subfolder/text_object_2 The point is that there's no index_html in /subfolder so /index_html will be acquested and by default it displays content of /text_object_1 and /text_object_2 The question is: we got text_object_1 and text_object_2 in /subfolder how could I let the acquested index_html in subfolder to use the objects inside the subfolder? If my desired effect could be achieved, that would be very useful as the whole site could use a master template at root, changing objects inside folder could show different content. While changing the root index_html will change the layout of the whole site Otherwise we have to put the same "index_html" inside every folder so that default view of folders will show their containing object content. If this is not easy, is there any other way to achieve the same effect? I don't want to use something like "http://myserver/?c=some_parameters" which is my current implementation (where site structured is not preserved or shown by URL) Thanks, Roger

NESTED IN STATEMENTS AND PASSING VARIABLES in DTML
by Theodore Patrick 20 Jul '00

20 Jul '00

What is the DTML syntax for nested in statements. Here is an example. ________________________________________ EXAMPLE 1: NO VARIABLE PASSING GOAL: loop 4 times and with each loop run the category_method and print out the results: <dtml-in "1,2,3,4"> <dtml-in "category_method(id='1')" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> WORKS! ________________________________________ EXAMPLE 2: VARIABLE PASSING GOAL: Loop in the active_category_method and for each row run the category_method passing a new 'id' variable and print out the results. <dtml-in "active_category_method()"> <dtml-in "category_method()" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> ERROR --> ID is not being passed to "category_method()" ________________________________________ Anyone have a solution out there? NOTE: active_category_method and category_method are SQL METHODS. Where 'id' is and SQL_VAR for category_method. Thanks in advance! Theodore E. Patrick Ishophere.com

On my linux box, I add another alias to the same IP in /etc/hosts for a separate user. I also switch between localhost and my hostname for a server on my own box. This also works for cookies.

THANKS A TON!!! I just found that the following solutions works also: I think the only difference is the id is evaluated in the namespace variable before invoking the SQL_METHOD <dtml-in "active_category_method()"> <dtml-in "category_method(id=(_['id']))" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> or <dtml-in "1,2,323,23,23"> <dtml-in "category_method(id=(_['sequence_item']))" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> ------------------------------------ Your point on the SQL_METHODS is a good one!

Where 'id' > is and SQL_VAR for category_method. This is FAQ material and should be inserted into either the DTML programmer's guide or the ZSQL Methods guide. It bites everyone who uses SQL methods eventually. ZSQL methods do not perform acquisition, but will look at REQUEST, change it to. <dtml-in "active_category_method()"> <dtml-call "REQUEST.set('id', id)"> <dtml-in "category_method()" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> If you have a lot of arguments that need to be captured, you can build a DTML Method, say setup_category_method_parameters that has these builds the REQUEST. Then your dtml can look like: <dtml-in "active_category_method()"> <dtml-call setup_category_method_parameters> <dtml-in "category_method()" size=100 start=query_start> id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid> </dtml-in> </dtml-in> > > Thanks in advance! > > Theodore E.

RE: Reversing acquisition?
by Spicklemire, Jerry 20 Jul '00

"B" is acquirable by "C" and "D", because it is within the context of a common container, "A". However, some other object, "E" that is acquired from higher up the containment chain may be affected by the nature of the "B" that is available to "D". Because of that, the "E" may appear differently than it would if presented as a component from some other containment chain. An easy example to grasp is to think of "B" as defining the background color of a page. If "E" is the master page template, other "B" objects in other chains could define the color scheme for the all the objects ("pages") in the parent folder. That's context. -----Original Message----- From: Luciano Ramalho [mailto:luciano@hiper.com.br] Sent: Thursday, July 20, 2000 1:23 PM To: Spicklemire, Jerry Subject: Re: Reversing acquisition?

Incorrect Article: Zope Costly enterprise option
by Eric L. Walstad 20 Jul '00

Hi Tom and the editors at InfoWorld, In regards to your article titled "Zope is a powerful open-source server" FYI, ZEO is now open source and free. It's been that way since March 2000. Is it possible to fix your article before too many folks get the wrong idea? Here's a link to all the details: http://www.zope.org/Products/ZEO/ZEOFactSheet Thanks, Eric Walstad.
