使用哪个运算符将新问题推送到问题数组中？我得到了以下格式的文档。使用哪个 mongo db 运算符将新问题插入到问题数组中，前提是我在提前。
例如，我想在 subchapterId“1”中插入一个新问题。
{
"chapterId": "38",
"subChapter": [
{
"subchapterId": "1",
"questions": [
{
"title": "Either his however modern. Stop central owner color type out. Interview five beyond interesting type suddenly.",
},
{
"title": "Amount himself foreign color moment gun together sit. Deal race range heart despite several. Rather activity eat dinner save mission western. Civil past public enter four then.",
},
{
"title": "Four former operation. Class continue away treatment.\nResponsibility condition dinner realize everything. Sign scene order quality yet. Within sing statement skill popular southern whole."
},
{
"title": "Where of coach nature ask page allow.\nType exist hotel time. Central site policy everyone safe. Official administration family somebody.",
},
{
"title": "Necessary dark these much region. Form sometimes seek. Future according detail piece section.\nNear everything admit. Senior Republican draw as expert market.",
}
]
},
{
"subchapterId": "2",
"questions": [
{
"title": "Audience still use group. Yourself building police. Play imagine serious reality population reach.\nHerself without member must think concern window finish."
},
{
"title": "Rule trip manage still. Imagine religious above race something successful.\nOnce base American series. Low page quite allow. Customer maybe base leave way under blood.",
},
{
"title": "Church audience anyone garden. Federal when individual style.Value billion morning need box whether. Coach traditional cold each us truth.",
}
]
}
]
}
最佳答案
你可以试试这个
const title = "this is the new question"
db.collection.update(
{ "subChapter.subchapterId": "1" },
{ "$push": { "subChapter.$.questions": { title } }}
)
