使用mongoDB查找并删除数组值

这是我希望使用设备数组值1查找的数据，用于查找和该对象，并从设备数组中删除该值

查找使用设备数组值1并从数组中删除该值

这是我当前的对象：

[ 
 {
    "devices": [
      "1",
      "2"
    ],
    "eui": "A5AC840871F01D65",
    "key": "5BCBF770D2B43638860F7DA3733ED1B3",
    
  },
  {
    "devices": [
      "3",
      "4"
    ],
    "eui": "A5AC840871F01D65",
    "key": "5BCBF770D2B43638860F7DA3733ED1B3",
    
  }
]

预期产出为：

 {
    "devices": [
      "2"
    ],
    "eui": "A5AC840871F01D65",
    "key": "5BCBF770D2B43638860F7DA3733ED1B3",
    
  },
  {
    "devices": [
      "3",
      "4"
    ],
    "eui": "A5AC840871F01D65",
    "key": "5BCBF770D2B43638860F7DA3733ED1B3",
    
  }
]

您可以使用

$pull

进行此操作。在这里：

db.collection.update(
    { devices: "1" },
    { $pull: { devices: "1" } }
)
