Mongodb批量写入错误

Question

我正在执行批量写入

bulk = new_packets.initialize_ordered_bulk_op()

bulk.insert(packet)

output = bulk.execute()

并得到一个错误,我解释为意味着数据包不是一个字典.但是,我知道这是一个字典.可能是什么问题呢？

这是错误:

    BulkWriteError                            Traceback (most recent call last)
    <ipython-input-311-93f16dce5714> in <module>()
          2 
          3 bulk.insert(packet)
    ----> 4 output = bulk.execute()

    C:\Users\e306654\AppData\Local\Continuum\Anaconda\lib\site-packages\pymongo\bulk.pyc in execute(self, write_concern)
583         if write_concern and not isinstance(write_concern, dict):
584             raise TypeError('write_concern must be an instance of dict')
    --> 585         return self.__bulk.execute(write_concern)

    --> 431             return self.execute_command(generator, write_concern)
432         else:
433             return self.execute_legacy(generator, write_concern)

    C:\Users\e306654\AppData\Local\Continuum\Anaconda\lib\site-packages\pymongo\bulk.pyc in execute_command(self, generator, write_concern)

297                     key=lambda error: error['index'])
    --> 298             raise BulkWriteError(full_result)
299         return full_result
300 

    BulkWriteError: batch op errors occurred

Answer 1

这可能有很多原因......
最好的是你尝试......捕捉......例外并检查错误

try:
    bulk.execute()
except BulkWriteError as bwe:
    print(bwe.details)
    #you can also take this component and do more analysis
    #werrors = bwe.details['writeErrors']
    raise

Answer 2

你应该检查两件事:

1. 如果要定义自己的密钥,请重复.
2. 能够管理自定义类型,在我的情况下,我试图传递一个无法转换为有效的objectId的哈希类型对象,这引导我到第一点,我感到陷入了一个恶性循环(我解决了)它将myObject转换为字符串.

逐个插入将让您了解正在发生的事情.

Answer 3

好吧,问题是我明确地分配了_id,结果是字符串大于12字节限制,我的坏.
