Javascript 猫鼬保存到2集合

大家好，这次我真的需要帮助。它困扰了我多少天了

model/user.js

var UserSchema = mongoose.Schema({
username:{
    type: String,
    unique: true,
    index:true
},
password:{
    type:String
},
email:{
    type:String,
    required: true
    // unique: true
},
authToken:{
    type: String,
    required: true,
    unique: true
},
IsAuthenticated:{
    type: Boolean,
    required: true
},
name:{
    type:String
},
field:{
    type:String
},
e_money:{
    type:Number //this is the integer form in mongoose
}
});


//accesible variable from the outside
var User = module.exports = mongoose.model('users', UserSchema);

var InfoUser = module.exports = mongoose.model('infouser', UserSchema);

var User = require('../models/user);

 var newUser = new User({
        name: name,
        email: email,
        authToken: authToken,
        IsAuthenticated: false,
        username: username,
        password: password,
        field: field,
        e_money: e_money //temporary emoney

    });

 var newUser2 = new InfoUser({
        name: name,
        email: email,
        authToken: authToken,
        IsAuthenticated: false,
        username: username,
        password: password,
        field: field,
        e_money: e_money //temporary emoney

    });




        //save the newly created user to database
    User.createUser(newUser,function(err, user){
        if(err) throw err;
        console.log(user);
   )};

   User.createUser(newUser2,function(err,user){
    if(err) throw err;
        console.log(user);
   )};

// You can add instance methods like this:
UserSchema.methods.createUser = function(user) {
  // Whatever you want to do here
};

var User = mongoose.model('users', UserSchema);
var InfoUser = mongoose.model('infouser', UserSchema);

exports.User = User;
exports.InfoUser = InfoUser;

/*
  You could also do this as:
  module.exports = { User: User, InfoUser: InfoUser };
*/

我如何保存是这样的

var UserSchema = mongoose.Schema({
username:{
    type: String,
    unique: true,
    index:true
},
password:{
    type:String
},
email:{
    type:String,
    required: true
    // unique: true
},
authToken:{
    type: String,
    required: true,
    unique: true
},
IsAuthenticated:{
    type: Boolean,
    required: true
},
name:{
    type:String
},
field:{
    type:String
},
e_money:{
    type:Number //this is the integer form in mongoose
}
});


//accesible variable from the outside
var User = module.exports = mongoose.model('users', UserSchema);

var InfoUser = module.exports = mongoose.model('infouser', UserSchema);

var User = require('../models/user);

 var newUser = new User({
        name: name,
        email: email,
        authToken: authToken,
        IsAuthenticated: false,
        username: username,
        password: password,
        field: field,
        e_money: e_money //temporary emoney

    });

 var newUser2 = new InfoUser({
        name: name,
        email: email,
        authToken: authToken,
        IsAuthenticated: false,
        username: username,
        password: password,
        field: field,
        e_money: e_money //temporary emoney

    });




        //save the newly created user to database
    User.createUser(newUser,function(err, user){
        if(err) throw err;
        console.log(user);
   )};

   User.createUser(newUser2,function(err,user){
    if(err) throw err;
        console.log(user);
   )};

// You can add instance methods like this:
UserSchema.methods.createUser = function(user) {
  // Whatever you want to do here
};

var User = mongoose.model('users', UserSchema);
var InfoUser = mongoose.model('infouser', UserSchema);

exports.User = User;
exports.InfoUser = InfoUser;

/*
  You could also do this as:
  module.exports = { User: User, InfoUser: InfoUser };
*/

问题是它总是说信息用户没有定义。是否有人可以试一试

问题是您正在通过同一个

模块导出两个不同的型号。导出

。相反，我建议您单独导出它们：

model/user.js

var UserSchema = mongoose.Schema({
username:{
    type: String,
    unique: true,
    index:true
},
password:{
    type:String
},
email:{
    type:String,
    required: true
    // unique: true
},
authToken:{
    type: String,
    required: true,
    unique: true
},
IsAuthenticated:{
    type: Boolean,
    required: true
},
name:{
    type:String
},
field:{
    type:String
},
e_money:{
    type:Number //this is the integer form in mongoose
}
});


//accesible variable from the outside
var User = module.exports = mongoose.model('users', UserSchema);

var InfoUser = module.exports = mongoose.model('infouser', UserSchema);

var User = require('../models/user);

 var newUser = new User({
        name: name,
        email: email,
        authToken: authToken,
        IsAuthenticated: false,
        username: username,
        password: password,
        field: field,
        e_money: e_money //temporary emoney

    });

 var newUser2 = new InfoUser({
        name: name,
        email: email,
        authToken: authToken,
        IsAuthenticated: false,
        username: username,
        password: password,
        field: field,
        e_money: e_money //temporary emoney

    });




        //save the newly created user to database
    User.createUser(newUser,function(err, user){
        if(err) throw err;
        console.log(user);
   )};

   User.createUser(newUser2,function(err,user){
    if(err) throw err;
        console.log(user);
   )};

// You can add instance methods like this:
UserSchema.methods.createUser = function(user) {
  // Whatever you want to do here
};

var User = mongoose.model('users', UserSchema);
var InfoUser = mongoose.model('infouser', UserSchema);

exports.User = User;
exports.InfoUser = InfoUser;

/*
  You could also do this as:
  module.exports = { User: User, InfoUser: InfoUser };
*/

然后，当您想要使用它们时：

var User = require('../models/user').User;
var InfoUser = require('../models/user').InfoUser;

我不能这样导出它吗

var InfoUser=module.exports=mongoose.model（'InfoUser'，UserSchema）有什么区别？问题是
module.exports
只导出一个对象（这就是它的工作方式），但您尝试使用它两次。您可以使用命名导出（我的示例的第一部分），将模型作为对象属性导出对象（我的注释示例），或者将它们分离到不同的文件中。它表示InfoUser.createUser不是函数：（是的，createUser不是mongoose的默认函数。请参阅我的编辑以了解如何添加实例方法（像createUser）。如果您只想将实例保存到数据库中，我只需要使用
.save（）
，所以它就像
newUser.save（）
现在它说不能读取未定义的属性“createUser”。我这样做
InfoUser.methods.createUser（newUser2，function（err，user）{If（err）throw err；console.log（user）；}）；//将新创建的用户保存到数据库user.methods.createUser（newUser，function（err，user）{if（err）throw err；console.log（user）；
