ValueError: 无法将'01234SS'转换为十进制整数

Question

我想知道，为什么我会收到“invalid literal for int() with base 10 error”的错误，但在交互模式下却运行得很好？

fees = {u'nid':u'179', u'type':u'fees',  u'jamb_no': u'01234SS'}
    for fee in fees:
      # Transaction model
      try:
        txn = Transaction()
        txn.nid = int(fee.get(u'nid'))
        txn.type = options.get(u'type')
        txn.jamb_no = fee.get(u'jamb_no') # invalid literal for int() with base 10
        txn.save()

Models.py

class Transaction(models.Model):
    id = models.AutoField(primary_key=True)
    type = models.CharField(max_length=50)
    nid = models.IntegerField()
    jamb_no = models.CharField(max_length=20, blank=False)

错误追踪信息：

    res = func(*args, **kwargs)
  File "api\tasks.py", line 142, in queue_transaction
ValueError: invalid literal for int() with base 10: '01234SS'

在交互提示符下，这个运行得很好。

>>> fees = {u'jamb_no': u'01234SS'}
>>> fees.get(u'jamb_no')
u'01234SS'
>>>

>>> jamb_no = u'01234SS'
>>> str(jamb_no)
'01234SS'

请帮帮我。我已经为这个问题纠结了两天了。

这个问题和celery有关。当我对tasks.py文件做了修改后，celery需要重新启动。但是我没有重新启动，这就导致即使状态已经改变，还是会出现重复的错误信息。
