Catch/Raise it

Classic try/catch scheme.

We only Raise errors from the rest_framework.exceptions.

  from rest_framework.exceptions import ParseError
  ...
  try:
    for x in stream_data['template']['data']:
      json_data[x['name']] = x['value']
    except KeyError as e:
      detail = "%s field required. " % e 
       detail += template_valid_str  
       raise ParseError(detail=detail)
