Question

我的收藏集中有以下文件。

{ 
    "_id" : ObjectId("5c98760c27b9fb1266f996b3"), 
    "user_id" : ObjectId("5c8109785b9a5427b167542a"), 
    "permissions" : [
        {
            "dashboard" : [
                "Pie Chart", 
                "Bar Chart"
            ], 
            "product management" : [
                "update", 
                "delete", 
                "list", 
                "insert"
            ], 
            "app user listing" : [
                "insert", 
                "update", 
                "delete", 
                "list"
            ]
        }
    ]
}

我正在尝试执行以下查询：

db.user_permissions.update(

    { user_id: ObjectId("5c8740860c5dcf6c615c1ba3") },
    { 
        "permissions.app user listing": ['inserts']
    }

)

我要做的是更新“应用程序用户列表”的值。

任何帮助表示赞赏。

编辑：这就是我想要的

            ], 
            "product management" : [
                "update", 
                "delete", 
                "list", 
                "insert"
            ], 
            "app user listing" : [
                "inserts"
            ]
        }
    ]
}

我想用数组更新给定键的值。

Answer 1

这适用于mongo的所有版本，您需要第二个参数进行查找，

    db.myColl.update( 
    {
        "user_id" : ObjectId("5c8109785b9a5427b167542a"),"permissions.app user listing":["insersssts"] 
    },
    {
        $set: {
        "permissions.$.app user listing":["insertss"]      
    }
    });

尝试如下：

db.user_permission.update(
    {
        "user_id" : ObjectId("5c8109785b9a5427b167542a")
    },
    {
        $set: {
            "permissions.$[].app user listing": ['inserts']
        }
    },
    {
        upsert:false
    }
)

运行查询之前的数据：

{
    "_id" : ObjectId("5c98760c27b9fb1266f996b3"),
    "user_id" : ObjectId("5c8109785b9a5427b167542a"),
    "permissions" : [
        {
            "dashboard" : [
                "Pie Chart",
                "Bar Chart"
            ],
            "product management" : [
                "update",
                "delete",
                "list",
                "insert"
            ],
            "app user listing" : [
                "insert",
                "update",
                "delete",
                "list"
            ]
        }
    ]
}

运行查询后：

{
    "_id" : ObjectId("5c98760c27b9fb1266f996b3"),
    "user_id" : ObjectId("5c8109785b9a5427b167542a"),
    "permissions" : [
        {
            "dashboard" : [
                "Pie Chart",
                "Bar Chart"
            ],
            "product management" : [
                "update",
                "delete",
                "list",
                "insert"
            ],
            "app user listing" : [
                "inserts"
            ]
        }
    ]
}
