First line of Template Operations section Just as <dtml-var foo> is the most fundamental statement of DTML, replace="expr" and insert="expr" are the basic workhorses of TAL. Should read Just as <dtml-var foo> is the most fundamental statement of DTML, replace="expr" and content="expr" are the basic workhorses of TAL. -- Steve Drees SysAdmin/Software Developer/Web Geek/Chief Bottle Washer "A problem well-stated is a problem half-solved." http://www.christianmp3zone.com/savanna

how to change a title from python script?
by alex 19 Apr '01

19 Apr '01

Hey guys, does anyone of you know how can an object title be changed without using the ugly manage_edit() method ? I was expecting something more intuitive as in dtml_method.title = 'new title instead of: dtml_method.mange_edit(data=dtml_object, title='new title') reasons why I dont like manage_edit() ? - It's a complete different method on each object. so you have to call it with different arguments depending the object you want to edit. - It's not intuitive at all! thanks for your help !

hasRole (Bug or My brain is dead?)

Just a suggestion: You may want to consider whether it would be better to test whether the user has the appropriate permission using has_permission(), rather than for whether they have a particular role.

Problem with xmlrpc and manage_pasteObjects
by Juan Carlos Coruña 19 Apr '01

19 Apr '01

I have another xmlrpc replated problem: If I test the following script (python) with the Zope management interface it works ok, but if I call the script from outside Zope using xmlrpc I become an Fault error: xmlrpclib.Fault: <Fault -2: 'Unexpected Zope error value: Add Documents, Images, and Files'> This is the script: # Create a unique document id id = 'pepe' context.tmp.manage_addProduct['OFSP'].addDTMLDocument(id, title="", file='esto es una prueba') doctmp = getattr(context.tmp, id) doctmp.manage_addProperty('sender', 'loginName', 'string') doctmp.manage_addProperty('sessionId', 'session', 'string') # move the message to the queue obj = context.tmp.manage_cutObjects(ids=[id]) context.manage_pasteObjects(obj) return id If I comment the line "context.manage_pasteObjects(obj)" Zope doesn't produce the error response. Is there a limitations using manage_pasteObjects with xmlrpc? Any solutions?

ZPT/TALES question
by Tim Moore 19 Apr '01

19 Apr '01

OK, so my site has a standard METAL template that all of the templates in the site use. It contains navigation links and such. I want one of those links to always go to the index_html page that's at the same level of the hierarchy as the standard template macro. The problem is that if I use a path like "here/index_html/absolute_url", then "here" is considered relative to the template that uses the macro, not the one that defines it. Can anyone offer any suggestions? thanks! -- Tim Moore

Reading uploaded file headers
by Greg Green 19 Apr '01

19 Apr '01

I am trying to read the header of a file uploaded in a REQUEST. I can get the filename and the data, but reading the headers gets me an authorization failure. Here is the python script: if file.headers.has_key('content-type'): type = file.headers.get('content-type') else: type = 'text/plain' return [file.filename, type, file.read()] If I remove the first 4 lines, everything works fine. Leave them and I the script doesn't work. Please reply to me off of the list as well, as I am not subscribed. Thanks. -- Greg Green Advanced Design Systems Math & Computing Technology Boeing (425) 865-2790

I have tested it on: Zope 2.3.1 and Zope 2.3.2b1 and the refcounts grows, but on Zope 2.2.4 it seems to work correctly.

Growing Refcounts
by Juan Carlos Coruña 19 Apr '01

19 Apr '01

Hi, invoking a xmlrpc call on any method, for example calling the default index_html dtml method, causes the delta of xmlrpclib.Unmarshaller and xmlrpclib.FastParser to increase without freeing instantes. After testing with diferent Zope versions I have discovered that calling the same method on Zope 2.2.4 works ok. Can anybody report the same problem? Is there a bug in the latest versions? Any solutions?

Can dtml-in iterate over a list of lists?
by Dunigan, Craig 19 Apr '01

19 Apr '01

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.

ZGETMAIL ? => Zope wget + mail-this-page
by Jason Cunliffe 19 Apr '01

19 Apr '01

Hi A popular feature for some is mail-this-page-to-a-friend. Depending on the circumstances, this ranges from lame harassement to a cool and useful thing. Mostly on the lame side imo, but can offset problem of heavy frames use. Sending a URL is often all that is requirtrd but for dynamic sitses this may or may not produce the intended result. so I am wondering if anyone has already come up against this with Zope, or has good suggestions for doing so. I can imagine a small product, ZGETMAIL, which harnesses a server-side wget tool to snapshot the selected current page in HTML, timestamp it and send or stash it like a digital postcard. Mail-this-Zopepage-to-a-friend would then allow one to send a special url linking to the location holding the snapshot HTML. The goal is to reduce confusion from forwarding URLs whose content changes, and to make it as easy and hassle free as possible to do so [no outlook express instaces screwing things up etc]. Useful especially for people logged into unfamiliar web terminals while away from laptop/home/office. - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']
