i have a Zope 2.1.6 (py 1.5.2) [yes, it stinks, tell my boss] this means i have no "bindings" in Zopes Python Method Interface. i try to call from DTML-Document(s) Python Method(s) (which call ZSQL-Methods). Both Python Methods and ZSQL-Methods have Parameters. Using <dtml-call "Top_upd(_.None, _, arg_TI=TOP_ID, arg_tls=toplangs, arg_tns=topnames) "> gives Error Type: TypeError Error Value: keyword parameter redefined ...traceback ...lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: Top_upd) (Info: ((None, <TemplateDict object at 871cfd8>), {'arg_tns': ['DTML', 'DTML'], 'arg_tls': [1, 2], 'arg_TI': '1'}, None)) i dont understand this error message, i changed every formal argument to avoid name clashes. i have tried calling also with - ( this, _, kw-args) same, but different traceback...lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: Top_upd) (Info: ((<Python Method object at 8611590>, <TemplateDict object at 8672a98>), {'arg_tns': ['DTML', 'DTML'], 'arg_tls': [1, 2], 'arg_TI': '1'}, None)) TypeError: (see above) [aside: why "this" in a DTML-Document leads to <Py Meth Obj> i have no idea] - ( kw-args) The last leads to Error Type: NameError Error Value: TOP_ID_NAME_upd # <-- zsql-method ...lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: Top_upd) (Info: ((), {'arg_tns': ['DTML', 'DTML'], 'arg_tls': [1, 2], 'arg_TI': '1'}, None)) File <string>, line 16, in Top_upd NameError: (see above) a) Is there a definite how-to/reference for calls of anything callable from anything able to call including parameter passing b) what have i made wrong and how to do it right?
