Hi, I want to call a python script from DTML and pass the namespace, the trouble is, the PS needs to be called from a python expression in DTML. So, taking the simple DTML method: <dtml-var standard_html_header> <dtml-let test_thang="'Test Thang'"> <dtml-var "test_ps" html_quote> </dtml-let> <dtml-var standard_html_footer> ...and a simple python script (with namespace bound to _): return _['test_thang'] ..which of coruse, doesn't work, it gives me: <PythonScript instance at 01B17ED0> ..so change <dtml-var "test_ps" html_quote> to <dtml-var "test_ps()" html_quote> and now I get: Error type: KeyError Error value: test_thang ...fair enough thinks me, I need to do the old dtml trick and so change to: <dtml-var "test_ps(_.None,_)" html_quote> ...and now I get: Error type: TypeError Error value: no arguments expected ...OK, irritating, but lets try changing the parameter list to 'context, _': Finally I get what I want: Test Thang However, now I want to call it somewhere else as just <dtml-var test_ps>, I get: Error type: TypeError Error value: not enough arguments; expected 2, got 0 ...at this point my head exploded and I thought I'd mail the list. Can anyone explain how Ishould eb doing this? cheers, Chris
