This was the 'syntax error' that John Fabiani was getting last week.
I had created a fix and sent it to him, and was waiting for
confirmation that it solved his problem. I know that the docstring
said it would return None if the field isn't in the DataStructure, but
I think that if we can determine the field type, we should return it,
no?
Here's my fix; try it out on your stuff and let me know if it works
for you. If it's OK, we can change the docstring to reflect this change.
def getDataTypeForField(self, fld):
"""Given a field name, returns its Python type, or None if no
DataStructure information is available.
"""
if fld in self.VirtualFields:
return type(self.getFieldVal(fld))
ds = self.getDataStructure()
if not ds:
return None
try:
fldInfo = [rec[1] for rec in ds
if rec[0] == fld][0]
except IndexError:
raise ValueError, _("Field '%s' does not exist in the
DataStructure") % fld
return dabo.db.getPythonType(fldInfo)
