让我们说我在Mongodb上有这个json:
{
"_id": {
"$oid": "5b37f4b5fe0cd65b1739641b"
},
"email": "sample@me.com",
"username": "Sample",
"password": "$2b$10$Zpynx8wTgqQftUO3m1tLUO8lNHtBtxl0i7yk84rRkVzcTmB9zO7Mu",
"__v": 0,
"tds": [
{
"_id": {
"$oid": "5b3bebb247737b77b2ecc398"
},
"category": "Projects",
"todos": {
"_id": {
"$oid": "5b3bebb247737b77b2ecc397"
},
"todo": "something to do"
}
},
{
"_id": {
"$oid": "5b3bec41dc270277bae759d6"
},
"category": "Main",
"todos": {
"_id": {
"$oid": "5b3bec41dc270277bae759d5"
},
"todo": "Other to do"
}
}
]
}
如何更新待办事项? 例如:
{
"_id": {
"$oid": "5b3bebb247737b77b2ecc397"
},
"todo": "something to do"
}
进入
{
"_id": {
"$oid": "5b3bebb247737b77b2ecc397"
},
"todo": "Lets do something"
}
我在nodeJS上尝试使用select,$ push,$ set,但是任何人都可以做到这一点。也许有一个我不知道的过滤器。当我沉迷于此两天后,我决定放弃。
模式:
var UserSchema = new mongoose.Schema({
email: {
type: String,
unique: true,
required: true,
trim: true
},
username: {
type: String,
unique: true,
required: true,
trim: true
},
password: {
type: String,
required: true,
},
passwordConf: {
type: String,
required: true,
},
tds:{}
})
;

带有有效ID的新有效json。

您可以使用mongoose中的updateOne()和updateMany()函数更新json数据,如下所示:
if(this.props.dataLoaded){
<loadingComponent></loadingComponent>
} else {
//operation is performed
}
