これが、棚のレコードを更新している私のコードです

def updateRecord(db, form):
    if not 'key' in form:
        fields = dict.fromkeys(fieldnames, '?')
        fields['key'] = 'Missing key input'
    else:
        key = form['key'].value
        if key in db:
            record = db[key]
        else:
            from person import Person
            record = Person(name='?',age='?')
        for field in fieldnames:
            setattr(record, field, eval(form[field].value))
        db[key] = record
        fields = record.__dict__
        fields['key'] = key
    return fields

shelve から値を取得しようとすると、このエラーが発生します

>>> import shelve
>>> db = shelve.open('class-shelve')
>>> db['sue'].name
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/shelve.py", line 121, in __getitem__
    f = StringIO(self.dict[key])
  File "/usr/lib/python2.7/bsddb/__init__.py", line 270, in __getitem__
    return _DeadlockWrap(lambda: self.db[key])  # self.db[key]
  File "/usr/lib/python2.7/bsddb/dbutils.py", line 68, in DeadlockWrap
    return function(*_args, **_kwargs)
  File "/usr/lib/python2.7/bsddb/__init__.py", line 270, in <lambda>
    return _DeadlockWrap(lambda: self.db[key])  # self.db[key]
KeyError: 'sue'

何が起こっているのですか？
