postman typeerror Benutzer ist keine Funktion

Question

Ich benutze Nodejs und mongodb, um die Entwicklung einer Website zu üben, aber ich habe ein Problem. mein server.js Code ist wie folgt:

var express=require('express'); 
 
var morgan=require('morgan'); 
 
var mongoose=require('mongoose'); 
 
var bodyParser=require('body-parser'); 
 

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

 
var app=express(); 
 

 
mongoose.connect('mongodb://root:abc123@ds021172.mlab.com:21172/test', function(err){ 
 
    if(err){ 
 
    console.log(err); 
 
    } else{ 
 
    console.log("Connected to the database"); 
 
    } 
 
}); 
 

 

 
//Middleware 
 
app.use(morgan('dev')); 
 
app.use(bodyParser.json()); 
 
app.use(bodyParser.urlencoded({ extended: true})); 
 

 

 

 
app.post('/create-user', function(req, res, next){ 
 
    var user=new User(); 
 

 
    user.profile.name=req.body.name; 
 
    user.password=req.body.password; 
 
    user.email=req.body.email; 
 

 

 
    user.save(function(err){ 
 
    if(err) return next(err); 
 

 
    res.json('Successfully created a new user'); 
 
    }); 
 
}); 
 

 

 

 

 

 
app.listen(3000, function(err){ 
 
    if(err) throw err; 
 
    console.log("Server is running on port 3000"); 
 
});

und mein user.js Code ist wie folgt:

var mongoose=require('mongoose'); 
 
var bcrypt=require('bcrypt-nodejs'); 
 
var Schema=mongoose.Schema; 
 

 

 
/* The user schema attribution/chatacteristics/field */ 
 

 
var UserSchema = new mongoose.Schema({ 
 
    email: {type: String, unique: true, lowercase: true}, 
 
    password: String, 
 
    profile: { 
 
    name: {type: String, default: ''}, 
 
    picture: {type: String, default: ''} 
 
    }, 
 

 
    address: String, 
 
    history: [{ 
 
    date: Date, 
 
    paid: {type: Number, default: 0}, 
 
    //item{type: Schema.Types.ObjectId, ref: ''} 
 
    }] 
 

 
}); 
 

 

 
/* Hash the password before we even save it to the datebase */ 
 

 
UserSchema.pre('save', function(next){ 
 
    var user=this; 
 
    if(!user.isModified('password')) return next(); 
 
    bcrypt.genSalt(10, function(err, salt){ 
 
    if(err) return next(err); 
 
    bcrypt.hash(user.password, salt, null, function(err, hash){ 
 
     if(err) return next(err); 
 

 
     user.password=hash; 
 
     next(); 
 

 
    }); 
 
    }); 
 

 

 
}); 
 

 

 

 
/* compare password in the database and the one that the user type in */ 
 
UserSchema.methods.comparePassword=function(password){ 
 
    return bycrypt.compareSync(password, this.password); 
 
} 
 

 

 
module.exports=mongoose.model('User', UserSchema);

aber wenn ich Postbote um zu versuchen, die Daten wie folgt zu posten:

können Sie mir helfen, dies zu beheben Problem?

Answer 1

änderte ich diese Zeile:

var UserSchema = new Schema({ 

in user.js Datei, so festgelegt, so das Problem. Aber ich weiß nicht warum
