Question

我的注册表数据未发布在猫鼬数据库中，这是我的代码

我的代码在从数据库中获取数据但未发布代码时有效请帮助我[]

    app.set('views', path.join(__dirname, 'views')); 
         app.set('view engine', 'jade');
         app.use(bodyParser.json());
         app.use(express.static(path.join(__dirname, 'public')));
         app.use(bodyParser.json()); app.use(bodyParser.urlencoded( extended: false ));



**mongoose connection** 

     mongoose.connect("mongodb://localhost:27017/change")

       .then(() => console.log('Connected to MongoDB ...')) 
       .catch(err => console.error('Could not connect to MongoDB....',err));
架构

   // Schema
    const courseSchema = new mongoose.Schema(
        firstName: String, 
        fName: String,
        add1: String,
        add2: String,
        city: String,
        province: String,
        zip:Number,
        country: String,
        age: Number,
        gender: String,
        color:String,
        Height:Number,
        mTongue:String,
        moi:String,
        disability:String,
        religion:String,
        mHealth:String,
        name:String,
        contact:Number,
        add3:String,
        add4:String,
        city1:String,
        state:String,
        postal:String,
        country1:String,
        RTC:String,
        email: String,
        profileimage:
            type: String
        ,
        date:  type: Date, default: Date.now,
        isPublished: Boolean
    );`
路由

app.post("/addname",upload.single('profileimage'), (req, res) => 
const myData = new User(req.body);
myData.save()
    .then(item => 
        res.redirect('/');  
    )
    .catch(err => 
        res.status(400).send("Unable to save to database");
    );
