Mongodb $set未设置嵌套值
我正在尝试使用Mongodb $set未设置嵌套值,mongodb,mongoose,Mongodb,Mongoose,我正在尝试使用findOneAndUpdate设置$set，但我的嵌套值设置不正确 下面是我的模式的一个片段： ... courseMap: { hasCourseMap: { type: Boolean, default: false }, parentMap: { type: Schema.Types.ObjectId, ref: "CourseMap" }, colleges: [ { name: { type: String }

StudentProfile.findOneAndUpdate（{u id:user.profile}，update）之后
以下内容已更新，这是顶级键值，但未设置我的嵌套值
"courseMap":{
"hasCourseMap" : true,
"parentMap" : ObjectId("5e07fb5b40b723f03935cb31"),
"colleges" : [
{
"_id" : ObjectId("5dfee8128eacd562f0338678"),
"name" : "Eastfield"
},
{
"_id" : ObjectId("5e06a566559c3013687cc0f1"),
"name" : "University of North Texas at Dallas"
}
],
"ninth" : {
"hsCourses" : [
{
}
],
"collegeCourses" : [
{
}
]
},
"tenth" : {
"hsCourses" : [
{
}
],
"collegeCourses" : [
{
}
]
},
"eleventh" : {
"hsCourses" : [
{
}
],
"collegeCourses" : [
{
}
]
},
"twelfth" : {
"hsCourses" : [
{
}
],
"collegeCourses" : [
{
}
]
},
"year5" : {
"hsCourses" : [
{
}
],
"collegeCourses" : [
{
}
]
}
}
以下是更新前的文档片段：
...
"courseMap" : {
"hasCourseMap" : false,
}
...
您假设要将所有内容放入$set
，这是不正确的
您可以分解更新语句
考虑以下示例，我从文档开始：
{
a: 1,
c: [
"1",
"2"
],
d: [
{
d1: "3",
d2: "4"
},
{
d3: "5"
}
],
e: {
e1: [
"6",
"7"
]
},
f: [
]
}
当我跑步时：
db.inserter.updateOne({
},
{
$set: {
c: [
"3.3"
]
},
$push: {
f: {
d4: "5.5"
}
}
})
结果：
{
"_id": ObjectId("5e1de4b6afa8c2dd9dcfd79c"),
"a": 1,
"c": [
"3.3"
],
"d": [
{
"d1": "3",
"d2": "4"
},
{
"d3": "5"
}
],
"e": {
"e1": [
"6",
"7"
]
},
"f": [
{
"d4": "5.5"
}
]
}
诀窍
更新文档有两个部分（可以更多，您可以使用点表示法）$set和$push
{$set：{c:[“3.3”]}，$push：{f:{d4:“5.5”}
按原样运行查询时，它会处理以下输出：

我用于第九个
，第十个
等的$set
字段来自mongoose文档，我正直接尝试保存它们。我使用了.lean（）
，我的查询成功了。在更新之前你能提供你的文档吗happens@Yahya我添加了一个relevent键的片段。您使用我在问题中发布的update
对象运行了我的查询，并获得了输出？或者你是说你用你的技巧运行了一个查询，结果成功了？对不起，把我弄糊涂了。你的问题，没有任何改变
