如何在Mongodb中附加对象的属性？

Question

Example:

user : {
    "user_name" : "chicken_01",
    "password" : "123456",
    "skills" : {
        "PHP" : 7.0,
        "NodeJs" : 8.0,
        "MongoDB" : 8.0
    }   
}

I want to add "HTML/CSS" : 8.0 to "skills" inner object. What is the proper way to do it? Thank you!

Answer 1

is it like JS? if yes :

var userObj= JSON.parse(user);
userObj.skills.HTMLCSS = 8.0;
user = JSON.stringify(userObj);

Answer 2

db.users.update(
                 {'user_name' : 'chicken_01'}, 
                 {'$set' : 
                        {
                         "skills.HTML/CSS":8.0
                        }
                 })

Except with the name of your collection and not db.users .
