Try: <tr><td class="1"><dtml-var "_['sequence-item'][0]"></td></tr> <tr><td class="1"><dtml-var "_['sequence-item'][1]"></td></tr> Hope this helps!

H2L 4P5 -----Message d'origine----- De : Dunigan, Craig [mailto:craig.dunigan@esker.com] Envoyé : jeudi 19 avril 2001 15:01 À : 'zope(a)zope.org' Objet : [Zope] Can dtml-in iterate over a list of lists? I have a Python script called "listArticles" that accepts a sort parameter called "EWSortOrder," and returns a sorted list of lists. I would like to display the list of lists using a DTML method called "ArticleList" that looks something like this: <table> <dtml-in expr="listArticles(EWSortOrder)"> <tr><td class="1">sequence-item[0]</td></tr> <tr><td class="2">sequence-item[1]</td></tr> .... </dtml-in> </table> where sequence-item is obviously the list in the current iteration, but clearly Zope isn't recognizing it as a list: Error Type: KeyError Error Value: sequence-item[0] Traceback (innermost last): File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 187, in publish File /opt/Zope/ZopeInst/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: CatalogAware) File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 171, in publish File /opt/Zope/ZopeInst/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/OFS/DTMLMethod.py, line 189, in __call__ (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: ArticleList) File /opt/Zope/ZopeInst/lib/python/DocumentTemplate/DT_In.py, line 711, in renderwob (Object: listArticles(EWSortOrder)) File /opt/Zope/ZopeInst/lib/python/DocumentTemplate/DT_Var.py, line 276, in render (Object: sequence-item[0]) KeyError: (see above) Can I do this, and if so, how can I let dtml-in know to expect a list each time? I can't nest dtml-in's because each item in the sub-list is processed a little differently.

Custom unauthorized message
by Menard.Jean-Francois＠hydro.qc.ca 19 Apr '01

Is there a simple way to define a custom "Unauthorized" message, like a "Standard Unauthorized Message" dtml method? If not, why not?

Almost surely, your problem occurs because you do not call your DTML objects with the two optional but essential positional parameters. Usually call your DTML objects like this: <dtml-var "dtml_object(_.None,_,your_param1=v1,...)"> More info in the DTML section of URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html Dieter

Calling ZClass constructors programmatically...
by sean.upton＠uniontrib.com 19 Apr '01

19 Apr '01

Sorry to bring up this subject, as it seems to be a popular question on the list, but I'm not sure if there is a complete answer to the question in the list archives, HOWTOs, etc. I'm sure I am not alone in trying to find an answer to this... I have been trying a bunch of different things to instantiate a ZClass instance (in this case, it is a custom folder subclassed from ZCatalog:CatalogAware, and OFS:Folder). The ZClass constructor (which works when called by direct traversal from the factory form) is another PythonScript, and I am trying to call the constructor via a PythonScript elsewhere in the ODB hierarchy; my code to do that looks like this: #--------------------------------------------------------------------------- --- container.Control_Panel.Products.Classifieds.AdFolder_add(id=`item.id`, title=item['category'], shortTitle=item['category'], locationDepth=1, redir=0) #--------------------------------------------------------------------------- --- The problem with this is that it creates the instance in the namespace of the product folder where the AdFolder_add constructor resides. I would use container.manage_addProduct['Classifeds'].AdFolder_add() ... but this won't work, because manage_addProduct doesn't understand what 'Classifieds' is (though it does when called through the web and this also works fine programmatically for OFS:Folder...). The code for my constructor is below; I am wondering if there is a way to adjust the script that calls the constructor to have it (somehow) pass the namespace of the calling folder (acquisition parent of the calling script) to the constructor method? Any help anyone might have would be greatly appreciated. If I can find an answer, I will try to piece together a howto... Thanks, Sean ## Script (Python) "AdDayFolder_add" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=id, title, shortTitle, redir ##title= ## #--------------------------------------------------------------------------- --- #--- Trap for no id, this sucks, and we quit... if not id: return 'Doh!

You code looks for an object with name "sap_root.leaves.merkmale.merkmale_index". The '.' are not interpreted as the attribute access operator but are passive parts of the name.

Some hackery is necessary to convince your browser to no longer send your id and password (that's what logged in means with HTTP basic authentication). Zope's logout page uses "<dtml-raise Unauthorized>" for this hackery. You will get an "unauthorized" whatever you give as user/password. But most browsers forget the old login information after you gave them once a new one (which, of course, fails too). You may read the "Web Publishing" section of URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html if you want to learn more about basic authentication. Dieter

Zope crashing (still)
by Ron Bickers 19 Apr '01

19 Apr '01

After applying some CVS updates to PythonScripts as posted (last week I believe), I was hoping Zope wouldn't crash. However, after 4 days, it restarted with the following: ------ 2001-04-16T19:51:12 ERROR(200) zdaemon zdaemon: Mon Apr 16 15:51:12 2001: Aiieee! 888 exited with error code: 4 ------ Any clues? _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

Modifying form input which is passed as a record
by Richard Ettema 19 Apr '01

19 Apr '01

Hi, I have a form that passes info as a record with the following type of info: [a: 'bob', b: 'silver', a: 'trev', b: 'gold', a: 'nig', b: 'bronze', a:'lee', b:'gold'] I want to work thru this info and pick out all the records with a key 'b' equal to 'gold'. I want to place this into a new key-value record (or list?) to use later. So it would create: [a: 'trev', b: 'gold', a:'lee', b:'gold'] I cant work out how to do this. My main problem is inserting key names to make the key-value pairs. I have got around this by creating a list within a list but this has no keys: [ ['trev','gold'], ['lee','gold'] ] Thanks for any ideas. Richard
