I have an SQL database that I want to populate using an external Python method (because I have file I/O code). So I have something like this: DTML Document named import_file which has: <dtml-call "parsefile()"> ---- parsefile is my external Python method. def parsefile (self): # blah, blah self.record_info (arg1=value1,arg2=value2) ---- record_info is a DTML document <dtml-unless "LookupPrinter(printer=printer)"> { random code here } ---- And LookupPrinter is a ZSQL Method So I have: DTML Document -> External Python Document -> DTML Document -> ZSQL Document Is this a sane thing to have my External Python Document calling back to DTML Documents? I keep getting name error on the LookupPrinter. I tried putting: <dtml-unless "LookupPrinter(_.None, _,printer=printer)"> and I still get the name error. In essence I am trying to have code that will parse a file and then record the results in my database. Thanks. Becky.
