This can easily result in a string, at least in a different object type. Dieter

You can either use a default value for your checkbox control: <input type="hidden" name="mycheckboxname:int:default" value="0"> or set it in your action: <dtml-unless mycheckboxname> <dtml-call "REQUEST.set('mycheckboxname',0)"> </dtml-unless> More details in URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html Dieter

Hello, I try to build a breadcrumb navigation root_folder : forum : Topic But with my code I get as forum title only the title I gave at its creation, when I call a method, e.g. search http://domain/forum/search will give root : forum : forum When I make search a DTML-Document (instead of DTML-Method) I get root : search : search And with any topic I get root : topic : topic : topic Does anybody know how to do this correct or where this error is coming from? Please find my code below. Thanks Ulrich <title> <dtml-call "REQUEST.set('reverse_PARENTS', [])"> <dtml-in PARENTS skip_unauthorized> <dtml-call "reverse_PARENTS.insert(0, _['sequence-item'])"> </dtml-in> <dtml-in reverse_PARENTS> <dtml-with sequence-item> <dtml-var title_or_id> </dtml-with>  :  </dtml-in> <dtml-var title_or_id> </title> -- Searchengine Know How - Webpromotion - Optimization - Internal Search World Wide Web Publisher, Ulrich Wisser, Odensvag 13, S-14571 Norsborg http://www.publisher.de Tel: +46-8-53460905 Fax: +46-8-534 609 06

[Ann] Chapter "Basic Concepts" of my upcoming Zope book
by Dieter Maurer 18 Feb '01

18 Feb '01

Dear Zopistas, the chapter "Basic Concepts" of my upcoming Zope book is ready for preview. It covers Zope site building objects, Web publishing, name lookup, DTML, site management and Zope security. You find it at URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html I consider it a valuable resource beside (and probably after) the official Zope book. It covers many of the questions that recur often in Zope's main mailing list. It is currently in a pre-alpha state. I know of the following problems: * lack of graphics to explain difficult concepts (such as DTML namespace, acquisition and Zope's security model) * many broken links If external links are broken, it was my lazyness. Broken internal links are caused by Python's XML processing tools not yet being fully up to process DocBook. * synopsis sections look very strange, caused by small bugs in Norman Walsh's DocBook stylesheets * lack of a stylesheet to improve presentation Dieter

The official Zope animal
by Philipp Auersperg 18 Feb '01

18 Feb '01

We have found the official Zope animal: it is a fish that is rare but populated in whole europe. It can be found in the Austrian directory fish types: (the page is in german but when I have time I'll put a translated version of it onto our homepage) http://www.oefg1880.at/fische/zope.html Wouldn't that be the right animal to be put on the O'Reilly Book )): ...any comments?

My First Tweak
by Ben Ocean 18 Feb '01

18 Feb '01

Hi; I'm tweaking *Build a Searchable Job Board*. http://www.zope.org/Members/mukhsein/job_board_howto I need to create a pull-down list for those who want to enter data and those who want to select among entries. I want this pull-down list to obtain its elements from a foreign source (within Zope). Here are the particulars: Off the doc root (in Zope) there is a folder, let's call it *MyFirstFolder*. Within *MyFirstFolder is *Catalog*. Within *Catalog* is *entries*. Within *entries* is *entry_addForm*. In *entry_addForm* is the ZTML to be displayed, including where I would like to put my loop sequence to create a selection of options, pulling data from another file. This other file will be closer to the doc root, so acquisition *should* work, however... Within *Products* is *Classifieds*. Within *Classifieds* is *classifieds_entry*, which has a property sheet which has a method called *content_html* that references the variable referenced in *entry_addForm* that I need to turn into the aforementioned pull-down list obtained from the foreign source. Boy, I hope I've made that clear. Can you help? TIA, BenO

Re: DirtyWordsFilter
by Erik Enge 18 Feb '01

[jasonc(a)bigfoot.com] | how do I use ZCatalog to store all the words I want filtered and how | would I run this script on a string from a form? That depends on how you want it to interact with your application, I guess. But, as an easy way out, you could run the dirtyword-filter before you add the text to your objects. If you want to store all the words in ZCatalog you could just index a bunch of words (bad words, with meta_type set to 'bad_word') and do searches; (untested!) aString = 'lots and lots of angry-customer-bad-words' for word in string.split(aString, ' '): for catalog_brain in self.Catalog.searchResults(meta_type='bad_word'): bad_word = self.Catalog.getobject(catalog_brain['data_record_id_']) if word == bad_word: aString = string.replace(aString, word, '*bleep!*') return aString Add this as a Python Script in your Zope instance, make sure it can reach the ZCatalog (here named Catalog) by acquisition or directly, and call this script for every string that will be added to your objects. There are tons of caveats with this model. F ex, it doesn't catch up on words like 'b a d w o r d'. You could try to do something intelligent with it. Hm. Someone has probebly done this before you, in Perl or something, look at their algorithm. Another thing is that it is highly unoptimized, and could be slow (relatively speaking). If you want to use the stop-word list; lib/python/SearchIndex/Lexicon.py, line 128 (in Zope 2.2.1) has a method called set_stop_syn(), this might be what you want to use, although I wouldn't how to. On closer inspection I see that at the bottom of that file, a stop_words tuple is defined; a really, really ugly way to solve this would be to add your words there; around line 191. Also, to be really sophisticated (albeit, with a larger percentage change of also bleeping some words that shouldn't be bleeped; ie. they weren't bad words) you could use the soundex Python module. If you're doing this to remove stuff like the SCRIPT tag, REQUEST calls and those kind of things, I wouldn't recommend using soundex - obviously. Hope this helps!
