mongodb $ addToSet在另一个$ addToSet中添加

Question

在这个addToSet＆＃34;唯一＆＃34;：＆＃34;控制器＆＃34;，＆＃34;模块＆＃34;和＆＃34;变量＆＃34;是独特的领域， 如果任何一个字段更改意味着它将插入完整的＆＃34;唯一的＆＃34;它的工作正常，  但我需要插入如果唯一字段保持相同的意思 我需要插入新的＆＃34; cal＆＃34;数组关闭＆＃34;日期时间＆＃34;和＆＃34;价值＆＃34;，我该怎么做？

db.measurement.update({"siteId":"55","thingId":"IOT",
    "unique.controller":11.0,"unique.module":10.0,"unique.variable":"curent"},
    {$addToSet:{
        "unique": {
        "controller":11,
        "module": 10.0,
        "variable" : "curent",
        "calculation" : [ 
                {
                    "min" : "a",
                    "max" : "c",
                    "avg" : "",
                    "cal" : [ 
                        {
                            "Datetime" : "",
                            "value" : 345.0
                        }
                    ]
                }
            ]
    }}}); 

这是我的收藏：

    "siteId" : "55",
    "thingId" : "IOT",
    "Date" : 1234545.0,
    "unique" : [ 
        {

                    ]
                }
            ]
        },

                        }
                    ]
                }
            ]
        }
    ],

这是我试过的：

db.measurement.update({"siteId":"55","thingId":"IOT",
    "unique.controller":11.0,"unique.module":10.0,"unique.variable":"curent"},
    {$addToSet:{
        "unique": {
        "controller":11,
        "module": 10.0,
        "variable" : "curent",
        "calculation" : [ 
                {
                    "min" : "a",
                    "max" : "c",
                    "avg" : "",
                    "cal" : [ 
                        {
                            "Datetime" : "",
                            "value" : 345.0
                        }
                    ]
                }
            ]
    }}});
