MongoDB 中的嵌入式阵列插入

Question

For practice purposes, I have 3 users which I have inserted into my database.

JSON code:

[
    {
    "f_name": "Raf", 
    "l_name":"Bak", 
    "age": 19, 
    },
    {
    "f_name":"miltos",
    "l_name":"Bak", 
    "age": 56,
    },
    {
    "f_name":"eleni",
    "l_name":"kot", 
    "age": 27,
    }
]

I want to insert for every user a history array and within that array another array. I use the following JSON code but I get an error.

db.patientdata.insertOne({f_name:"Raf"},{$set: {history:["desease":"fever","treatment":"ponstan"]}})

Do I have to "$set" the 2nd array as well?

Thank you in advance.

edit after further meddling with this:

I also tired the following JSON code:

db.patientdata.updateOne({f_name:"Raf"},{$set: {"history":["desease","treatment"]}})
db.patientdata.updateOne({f_name:"Raf"},{$set: {"desease":["fever"]}})
db.patientdata.updateOne({f_name:"Raf"},{$set: {"treatment":["ponstan"]}})

but I there wasn't a second embedded array within the first one:

Answer 1

I inserted a new user from the beginning and it works fine.

JSON code:

db.patientdata.insert({f_name:"George",l_name:"Bak","age":29, history:[{disease:"doesn't know good programming",treatment: "study more"}]})
