Question

我的procedures集合中有对象。

我想更新5996c80fca423ce1228f7690中可用的item_id preferences.items的item_status。

我想获取所有提及item_id的记录，以便我们可以更新所有匹配项。

我假设您正在讨论更新status字段，因为我找不到名称为item_status的字段。如果是这种情况，则以下查询应该有效：

> db.procedures.updateMany({"preferences.$.items.$.item_id": "5996c80fca423ce1228f7690"}, {"$set": {"status": "new_status"}})

mongodb中的嵌套对象更新查询
