mongodb - How mongoose adds data to array documents

Question

For example, var PersonSchame = new mongoose.Schema({ {code...} }); How to add data to books at this time is a bit basic:)

ringa_lee · Answer

Do you mean to add elements to the books field of a piece of data in the database? If so, refer to the following example:

db.personModel.update({
    _id: xxx    //查询到特定的一条数据
}, {
    $push:{
        members: username
    }
}, (err) => {
    //update操作完之后的回调函数
});
