Hmm - with regard calling ZSQL method from PythonMethod, this works: def pythonmethod(self): a = [] for v in self.SQL_list_something(): a.append(v.field) return a <dtml-var pythonmethod> *But* of course I can't pass "self" over XMLRPC. Why does self.ZSQL_method() work, but: def pythonmethod(meth): a = [] for v in meth(): a.append(v.field) return a <dtml-var "pythonmethod(ZSQL_method)"> Give "__call__ not defined"?

Do PythonScripts obivate the need for this? I assume I can just do this: for record in context.folder.subfolder.SQL_method(val1='a',val2='b'): # do stuff Does that work? 2) When calling a DTML method over XMLRPC, <dtml-in "SQL_method(username=AUTHENTICATED_USER)"> doesn't work, but <dtml-in "SQL_method(username=REQUEST.AUTHENTICATED_USER)"> does. Why? 3) Why aren't record values (the return of an SQL method) marshallable over XMLRPC. I get this: cannot marshal <extension class ExtensionClass at 70356ff4> objects Regards, Phil _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
