Hi,
I need some advice. I still use dtml calls in my systems. My problem is if the user is searching for a record but the record is not found. The call is as follows:
<dtml-call "REQUEST.set('serial_number', serial_number)">
<dtml-in lookup_header_record> <dtml-call "REQUEST.set('equip_type', equip_type)"> <dtml-call "REQUEST.set('pr', pr)"> </dtml-in>
Modifying the REQUEST using REQUEST.set() is in general bad-style and a DON'T DO IT.
If the record is not found I get this error:
Error Type: KeyError Error Value: equip_type
True statement since there is not record and further in the form I am trying to output this variable. Are there any examples that either traps for an error or python script that can also lookup the record and true a found/not found status.
Look at the Python documentation try...except or whatever....you questions sounds like you really want to learn Python :-) -aj
