I have a patch for a bug I found in the DecimalValidator class in col.py. I
am getting messages saying no attribute 'name' of DecimalValidator. This is
is traceable to col.py, about line 1300:
def from_python(self, value, state):
if value is None:
return None
if isinstance(value, float):
value = str(value)
if isinstance(value, (str, unicode)):
connection = state.soObject._connection
if hasattr(connection, "decimalSeparator"):
value = value.replace(connection.decimalSeparator, ".")
try:
return Decimal(value)
except:
raise validators.Invalid("can not parse Decimal value '%s' in
the DecimalCol from '%s'" %
(value, getattr(state, 'soObject', '(unknown)')), value,
state)
if not isinstance(value, (int, long, Decimal,
sqlbuilder.SQLExpression)):
raise validators.Invalid("expected a decimal in the DecimalCol '%s',
got %s %r instead" % \
(getattr(self, 'name', '(unknown name)'), type(value), value),
value, state)
return value
The change is in the next-to-last line (the raise() call). The problem, as
I mentioned, is DecimalValidator having no attribute 'name' (a reference to
self.name). Changing self.name to getattr(self, 'name', '(unknown
name)')eliminates this problem and preserves a nice error message
showing you what
the problem is.
Likewise, there’s a line above this in the to_python() method that
could/should be changed similarly.
Sorry, I don’t know how to create a test for this, my code is rather
complex.
