只为pymongo remove throws TypeE设置一个限制

Question

在python2.7.3、pymongo2.7上

我试图在从pymongo集合中删除文档时设置justOne safety limiter。在

ufo.users指向有效的预初始化集合

>>> type(ufo.users)
<class 'pymongo.collection.Collection'>    

>>> ufo.users.remove({'emails.address': 'foo@bar.com'}, {'justOne': True})

TypeError: Wrong type for safe, value must be a boolean

将justOne值设置为“True”、“True”、“1”或“1”都会提供相同的错误消息。在

在查看包的本地缓存时，我在pymongo/common.py中找到了一个应该执行验证的函数：

^{pr2}$

还有。。。我不明白。我试着传递“真”和“真”。。。。在

这是包裹里的虫子吗？在

要正确设置justOne选项，我需要做些什么？在

Answer 1

在pymongo下，参数略有不同，如documentation

ufo.users.remove({'emails.address': 'foo@bar.com'}, safe=True)

这应该能解决问题
