Hi Dieter, Surprisingly, even though there's an error message, the product still manage to 'perform' its function, i.e. build a site from its template. <host>:8080/manage still works ok; i guess Data.fs not corrupted. *scratch head* - does zope like to raise false alarms?? Anyway, thanks for your help. regards, firestar ------Original Message------ From: Dieter Maurer <dieter(a)handshake.de> To: theebh(a)mail.com (Firestar) Sent: July 18, 2000 6:41:51 PM GMT Subject: Re: [Zope] Creating Factory Objects (Products) Firestar writes: > Haha, thanks for the 'wisdom' cookies:) Here are the last two lines of the > traceback: > > File /usr/local/Zope-2.1.6/lib/python/OFS/Application.py, line 249, in > __bobo_traverse__ > (Object: ApplicationDefaultPermissions) > File /usr/local/Zope-2.1.6/lib/python/ZPublisher/HTTPResponse.py, line 511, > in notFoundError > NotFound: (see above) I have to admit that in this case the end of the traceback tells not much about the problem. I found in the sources (ZPublisher.HTTPResponse) that the resource not found is indicated as an HTML *comment* in the error page. I do not know, why the implementers hide this information. Anyway, the traceback seems to suggest that the problem is immediately at the top level of your URL. Is it possible that your "Data.fs" is empty or otherwise in a strange state? What happens, if you access your site with "<host>:<port>/manage"? Dieter ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup

Announce: ZBabel a Translation Assistant for Zope
by Andrew Kenneth Milton 19 Jul '00

19 Jul '00

Some people have been bugging me to release this so here we go:- http://www.zope.org/Members/TheJester/ZBabel/ The doco is shambolic to say the least, and there are no examples at the moment and no list of what hooks are available. It does not automatically translate for you, it assists you to build a multi-lingual site once, and then maintain it in different languages, rather than building it once for every language (or rebuilding the same thing over and over). It does however make it pretty easy to get things going fairly cheaply. There is a trade off between resuable phrase lengths and making phrases unambiguous that you have to deal with. If it breaks, you get to keep both bits. Readme Excerpt: ------------------------------------------------------------------------ This is the ZBabel Translation System for ZOPE, the Z Object Publishing Environment (http://www.zope.org/) This is a phrase by phrase translation system, it allows you to translate key parts of your site, and the content if you desire. With this you don't need to maintain seperate source for each supported language, or mix different languages in your source. You can do your entire site in one language and then translate it without re-editing the source code. This system also automatically creates the catalogs as you go, you do not need to manually insert text strings into databases for translation. ZBabel comes as a two part kit, to help you with translating your ZOPE Content. The first part is the tag <dtml-babel> which allows you to register and translate your phrases. The second part is a the ZBabel Tower Product. This is a Folderish Object that does most of the legwork. You will need a ZBabel Tower Product installed somewhere that your documents can acquire it if you want translations to occur. If you do not install the product, the <dtml-babel> tag will simply return the existing text. -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 ABN: 83 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068 |akm(a)theinternet.com.au|

ZCatalog Reindex_object Problems
by Manuel Schulte 18 Jul '00

18 Jul '00

Hi, I've been struggling trying to get the catalog to index catalog aware objects. There are several messages from people with similar problems, in the archives, but none of the solutions seem to work. I have created a Product with a catalog aware class called Job_Request. The Product also has a Job_Request_addForm method and a Job_Request_add method. The form simply asks for user input for various fields and the Job_Request_add method is meant to create the class instance, set the properties, and index the object. In order to test the class I made an object which lists all items the catalog as well as allows me to search on a single field. The problem seems to be that the catalog will not update after I Input a value that the catalog has not yet seen for a particular field. Some Examples: 1. The catalog already has a Job_Request object with the agency_name property set to NASA. If I add another object to the catalog with agency_name = 'NASA', the result lists for an unrestricted search and a search restricted to NASA both contain the correct record. 2. I delete all objects where agency_name ='NASA' and then I add a new one with the same agency_name, I get the same results as above. 3. I add a new Job_Request where the value of agency_name is one that has yet to have been cataloged i.e. agency_name = 'NeverHadThisValue', and the results for an unrestricted search on agency_name shows the record, but the results restricted by agency_name = 'NeverHadThisValue' comes up empty. Any help on this would be greatly appreciated (Is it a bug? If so what's the best workaround).... Manuel What follows is the code for my Job_Request_add method and my SearchTest method: Job_Request_add: <dtml-var standard_html_header> <dtml-call "REQUEST.set('ts', ZopeTime())"> <dtml-call "REQUEST.set('id',_.str(_.int(ts)))"> <dtml-call "REQUEST.set('agency_name', agency_name)"> ......many more REQUEST.set's ....... <dtml-with "Job_Request.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.Job_Details.manage_editProperties(REQUEST)"> <dtml-call reindex_object> </dtml-with> <dtml-if NoRedir> <dtml-else> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect( DestinationURL+'/manage_workspace')"> <dtml-else> <dtml-call "RESPONSE.redirect( URL2+'/manage_workspace')"> </dtml-if> </dtml-if> <dtml-var standard_html_footer> TestSearch: <dtml-var standard_html_header> <H2>Entire Catalog</H2> <p> <dtml-in "Catalog(agency_name='')"> <BR> <dtml-var agency_name> <dtml-var id> </dtml-in> <H2>Single Record</H2> <p> <dtml-in "Catalog(agency_name='NewName')"> <BR> <dtml-var agency_name> <dtml-var id> </dtml-in> <H2>Try a Search</H2> <form action="available_positions_report" method="get"> <tr><th>Agency_name</th> <td><input name="agency_name" width=30 value=""></td></tr> <tr><td colspan=2 align=center> <input type="SUBMIT" name="SUBMIT" value="Submit Query"> </td></tr> </table> </form> <dtml-var standard_html_footer>

Then, your available objects should list a Z Oracle Database Connection. Add one. If not, go to ControlPannel/Products. There you should see a (maybe broken) ZOracleDA product. If it is broken, click on it. You will see a traceback that usually tells you what went wrong. Dieter

The proper usage of Sequence-item
by jesse 18 Jul '00

18 Jul '00

I'm improving on Smarter forms so that instead of having to hard code every field into the code that checks for errors, it automaticly reads the dictionary that is in REQUEST and checks every key in it. I'm trying to work with this... <dtml-call "REQUEST.set('finished','true')"> <dtml-in "REQUEST.keys()"> <dtml-comment> starting the loop </dtml-comment> <dtml-if "_[sequence-key].value('')"> <dtml-comment> I'm saying that if the current key is empty, display this. </dtml-comment> <li>Please fill in your <dtml-var "_['sequence-key']"> below <dtml-call "REQUEST.set('finished','false')"> </dtml-if> </dtml-in> <dtml-if "REQUEST.get('finished')=='true'"> <p>You're done! Thanks for your input <dtml-var fname>.</p> <p>You could put a link to somewhere else on your site here...</p> <dtml-else> <p> Please correct this and click the <i>Next</i> button to complete the form. </p> <dtml-var expr="mainform_include()"> </dtml-if> any input would be helpful.

I'm close to > getting them properly interfaced with DTML namespaces, so that DTML can > invoke Python Methods using simpler DTML syntax. I've followed this thread with particular interest. I'm almost 18 months old with Zope and have done many useful things with it. But my journey up the learning cliff has been punctuated by spells of doing other things (I'm not a programmer in real life) during which I inevitably forget most of what I've just learned about DTML (and slip back down the cliff). OK, this is true of most things (computer languages, foreign languages, mental arithmetic, parenthood, etc) - if you don't use it, you lose it. But there is something about DTML that distinguishes it (for me) from other languages - it's the rate at which it decays on you. Python's decay constant is much more favourable. So I've learned a rule of thumb - if I'm writing DTML and it isn't flowing then I really ought to be using Python. PythonMethods are nice but, as they stand, you only have access to built-in functions. So if you want to import modules you have to resort to External Methods. [Am I talking nonsense here? My empirical experience is that I can use string functions in a PythonMethod but not, say, stuff from the time module. Neither string nor time are built-in though ..... so why one and not the other?] The point of these reflections: * PythonMethods ought to be a high priority IMHO. * DTML is holding Zope back for the rest of us (and is arguably a "proprietary" component of Zope (in that you can't use it anywhere else) - this is a disincentive to many power-Perl,JSP,<name-your-scripting-poison> users I suspect. * Please can we import Python modules from PythonMethods (or can we already and I don't about it, or does this break the sandbox that PythonMethods is meant to provide)? * Don't worry about changing DTML syntax. It's an excellent marketing ploy to ensure good sales of the 2nd edition of The Zope Book ;-) Apologies for any misconceptions in any or all of the above.
