What zpt!? you submit to a dtml which calls a script that returns a value ... there's no zpt ... Anyway, your question is probably answered here: http://zope.org/Documentation/Books/ZopeBook/2_6Edition/ZPT.stx read the section "Creating a File Library with Page Templates" HTH -- //// (@ @) ----------------------------oOO----(_)----OOo-------------------------- <> Ojo por ojo y el mundo acabara ciego /\ Alexis Roda - Universitat Rovira i Virgili - Reus, Tarragona (Spain) -----------------------------------------------------------------------

SQL for PluggableUserFolder
by Jason Leach 22 Sep '04

22 Sep '04

Zope: Does anyone have a pluggin for PluggableUserFolder to do SQL authentication? I don't know if I should bother writing one, or just pump users into my LDAP server and auth from that. I do know I would like to use my own custom forms. Jason.

update existing instances of a class?
by John Schinnerer 22 Sep '04

22 Sep '04

Aloha, I have a python product that I have modified (most importantly by adding some properties). Some instances already exist that were created prior to adding these properties. I have heard it is possible to update the existing instances (so that they get the new properties) - is this true? If so, where might I find info on how to do this? thanks, John S. __________________________________ Do you Yahoo!? New and Improved Yahoo!

Can't locate PyObject_SetItem
by Jonathan Hobbs 22 Sep '04

22 Sep '04

I am trying to track down the cause of a performance problem in ZCTextIndex (OkapiIndex is the leading contender - thanks to Dieter to for the tip!) and have gotten as far as the 'score' routine in okascore.c - which references a routine called 'PyObject_SetItem', for which I cannot locate the source routine. Does anyone know where the source for the 'PyObject_xxx' routines are stored (linux installation)? Thanks in advance, Jonathan

Get mime type and filename without path in python
by Patrick Ulmer 22 Sep '04

22 Sep '04

Hi, I want to allow uploading files from my website and put it in a database. My short script works: if myfile and myfile.filename != '': container.dbUpdateFile (id=str (id_ds), myfile=myfile.read ()) Now I want to put the mimetype in the database put how can I get the mimetype? I try: import mimetypes guess_type(myfile.filename) but I got an the error "*You are not authorized to access this resource".* What's wrong? I also want to put the filename in my database, but the Internet Explorer gives me the filename with path. Is there a funtionc to get the filename without path? Thanks, Patrick

One problem that I find with ZSQL Methods is that I need to delete the connection_id attribute from the ZSQLMethods I create at class level: class MyClass(BaseClass): connection_id="MyConnectionID" _zsql_meth=ZSQLMethod('','','', arguments, template) del _zsql_meth.connection_id #Now connection_id will be acquiried from MyClass #Well I noticed that I could override connection_id #by using a connection_hook def getConnectionId(self): return self.connection_id _zsql_meth=ZSQLMethod('','','', arguments, template) _zsql_meth.connection_hook ="getConnectionId" #Now connection_id will be looked up by calling getConnectionId #on MyClass.

I hadn't thought about speed, so thanks for the tips :-) I'm using the Result object directly in Python as you describe, but mostly because I don't want to display tre result. I'm building a PluggableAuthenticationPlugin you see :-) The speed-up was a nice plus :-) Cheers, Johan -- Johan Carlsson Tel: + 46 8 31 24 94 Colliberty Mob: + 46 70 558 25 24 Torsgatan 72 Email: johanc(a)easypublisher.com SE-113 37 STOCKHOLM
