如何在主架构上插入或推送架构

Question

你好，我是新来的，却没有办法找到解决方法。

我在同一模型文件中有一个主模式和一个用户模式。首先，我正在注册主要模式。注册主架构后，我要注册用户架构。注册将由主要模式用户（ admin ）完成。因此，我还为 admin 创建了登录名并创建了JWT访问系统。通过同一系统，我现在要注册 users 并将其推送到主模式中提到的数组上。

我为用户架构创建了单独的控制器，但它正在mongodb上创建了一个新集合。

如何推送到同一文档的对象数组？

这是模型：-

var userrSchema = new mongoose.Schema({
    email :     {
                type: String,
                required: "Email can't be empty.",
                // unique: true
                },
    password:   {
                type: String,
                required: "Password name can't be empty."
                },
    firstName : {
                type: String,
                required: "First name can't be empty."
                },
    lastName : {
                type: String,
                required: "Last name can't be empty."
                },
    phoneNumber :   {
                type: String,
                required: "Reqired for further contact. Can't be empty."
                },              
    verify:     String,                                 
    role: String,   
    emailResetTokennn: String,
    emailExpiress: Date,
    saltSecret: String
});

mongoose.model('Userr' , userrSchema);

//define admin(main) schema 
var adminSchema = new mongoose.Schema({
    companyName : {
                type: String,
                required: "Company  name can't be empty.",
                required: false
                },  
    companyID:  {
                type: String,
                },              
    address :   {
                type: String,
                required: "Address can't be empty.",
                },
    contactDetails : {
                type: String,
                required: "Company contact number can't be empty.",
                },
    admins:     {
                        _id: mongoose.Schema.Types.ObjectId,
                        email :     {
                                    type: String,
                                    required: "Email can't be empty.",
                                    unique: true
                                    },
                        password:   {
                                    type: String,
                                    required: "Password name can't be empty."
                                    },
                        firstName : {
                                    type: String,
                                    required: "First name can't be empty."
                                    },
                        lastName : {
                                    type: String,
                                    required: "Last name can't be empty."
                                    },  
                        phoneNumber :   {
                                    type: String,
                                    required: "Reqired for further contact. Can't be empty."
                                    },
                        designation :   {
                                    type: String,
                                    required: "Designation can't be empty."
                                    },
                        verified: String,                               
                        role: String,
                        emailResetTokenn: String,
                        emailExpires: Date,
                        saltSecret: String,//this is user for encryption and decryption of password 
                        users:[ { type: mongoose.Schema.Types.ObjectId, ref: 'Userr' } ]    
    }           
});
mongoose.model('Admin', adminSchema);

编辑：-添加了主控制器：-

 module.exports.registerAdmin = (req, res, next) =>{    

        var admin = new Admin();
        admin.companyName = req.body.companyName;
        admin.address = req.body.address;
        admin.contactDetails  = req.body.contactDetails;
        admin.admins = {
                        email : req.body.email,
                        password: req.body.password, 
                        firstName : req.body.firstName, 
                        lastName : req.body.lastName,
                        phoneNumber : req.body.phoneNumber,
                        designation : req.body.designation,
                        role : "admin",
                        verified :"false",
                        users: []
        }; 
admin.save((err, doc) =>{
