pymongo中的collection.getIndexes()shell命令等效于什么? [英] What is the equivalent of the collection.getIndexes() shell command in pymongo?

问题描述

我似乎找不到作为pymongo的Collection对象的一部分实现的getIndexes()命令-这是故意的吗?它是在类层次结构中的其他地方实现的吗?

I can't seem to find a getIndexes() command implemented as part of pymongo's Collection object - is that intentional? is it implemented somewhere else in the class hierarchy?

如果不是，那么获得相同效果的pymongo规范方法是什么?

if it isn't, what's the pymongo canonical way for getting the same effect?

推荐答案

您可能正在寻找的是

What you might be looking for is index_information() at the Collection level. From the docs:

获取有关此收藏集索引的信息.

Get information on this collection’s indexes.

返回一个字典，其中的键是索引名(由create_index()返回)，值是包含每个索引信息的字典.

Returns a dictionary where the keys are index names (as returned by create_index()) and the values are dictionaries containing information about each index.

>>> db.test.index_information()
{u'_id_': {u'key': [(u'_id', 1)]},
u'x_1': {u'unique': True, u'key': [(u'x', 1)]}}
