【问题描述】:
我有这个文档结构
{
"_id": <OBJECT_ID>,
"orders": [
{
"userId": 1,
"handleName": "John Doe",
"orderAmount": 3,
"others": [
{
"userId": 1,
"handleName": "John Doe"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
},
{
"userId": 2,
"handleName": "Maria Gigante",
"orderAmount": 2,
"others": [
{
"userId": 1,
"handleName": "John Doe"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
},
{
"userId": 1,
"handleName": "John Doe",
"orderAmount": 4,
"others": [
{
"userId": 1,
"handleName": "John Doe"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
},
{
"userId": 3,
"handleName": "John Doe",
"orderAmount": 4,
"others": [
{
"userId": 1,
"handleName": "John Doe"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
}
]
}
我想更新具有1 的userId 和John Doe 的handleName 的所有对象。
请注意,对象可以具有相同的句柄名称但不同的用户 ID。这就是为什么我需要先将它与userId 匹配。
比如我想把句柄名改成Donald Stark
我想要这个结果:
{
"_id": <OBJECT_ID>,
"orders": [
{
"userId": 1,
"handleName": "Donald Stark",
"orderAmount": 3,
"others": [
{
"userId": 1,
"handleName": "Donald Stark"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
},
{
"userId": 2,
"handleName": "Maria Gigante",
"orderAmount": 2,
"others": [
{
"userId": 1,
"handleName": "Donald Stark"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
},
{
"userId": 1,
"handleName": "Donald Stark",
"orderAmount": 4,
"others": [
{
"userId": 1,
"handleName": "Donald Stark"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
},
{
"userId": 3,
"handleName": "John Doe",
"orderAmount": 4,
"others": [
{
"userId": 1,
"handleName": "Donald Stark"
},
{
"userId": 2,
"handleName": "Maria Gigante"
}
]
}
]
}
这是如何实现的?
更新: 我忘了我还有另一个内部数组也想更新。
