[Zope] Calling ZSQL from PythonMethods (was RE: [Zope] ZSQL, Python meth ods and XMLRPC) ods and XMLRPC)

[Mayers, Philip J]

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"?

Phil

I've three questions (but I'm making progress!):

1) In 2.2.5, how can I call a ZSQL method from a Python Method - I'm passing
the method in as a parameter, and the furthest I get says "__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

Phil
