我试图通过使用Handlebars作为视图引擎的处方集将数据放入数据库，当我单击按钮发送数据时，出现此错误消息：TypeError：无法读取未定义的属性（阅读“matricula”）。
这是我创建“Alunos”表的迁移文件：

module.exports = {
  up: async (queryInterface, Sequelize) => {
   return queryInterface.createTable('alunos', {
    id: {
      type: Sequelize.INTEGER,
      autoIncrement: true,
      allowNull: false,
      primaryKey: true,
    },
    matricula: {
      type: Sequelize.INTEGER,
      allowNull: false,
    },
    nome: {
      type: Sequelize.STRING,
      allowNull: false,
    },
    curso: {
      type: Sequelize.STRING,
      allowNull: false,
    },
    ano: {
      type: Sequelize.INTEGER,
      allowNull: false,
    },
    createdAt: {
      type: Sequelize.DATE,
    },
    updatedAt: {
      type: Sequelize.DATE,
    },
   });
  },

  down: async (queryInterface, Sequelize) => {
   return queryInterface.dropTable('alunos');
  }
};

这是Aluno的模型：

const { DataTypes } = require('sequelize');
const sequelize = require('../config/sequelize');

const Aluno = sequelize.define('alunos', {
    matricula: DataTypes.INTEGER,
    nome: DataTypes.STRING,
    curso: DataTypes.STRING,
    ano: DataTypes.INTEGER,
});

module.exports = Aluno;

下面是config.js文件：

module.exports = {
  dialect: 'postgres',
  host: 'localhost',
  username: 'postgres',
  password: '123456',
  database: 'novoProjeto',
  define: {
    timestamps: true,
  },
};

这是sequelize.js文件：

const database = require('./config');
const Sequelize = require('sequelize');
const sequelize = new Sequelize(database);

sequelize.authenticate().then(function(){
    //message if connects
    console.log('Conexão executada com o banco de dados.')
}).catch(function(err){
    //message if it doesn't
    console.log('Conexão não executada com o banco de dados devido a: ' + err)
});

module.exports = sequelize;

下面是index.js文件：

const express = require('express');
const app = express();
const { engine } = require('express-handlebars');
const bodyParser = require('body-parser'); 
const routes = require('./routes/routes');

app.use(routes);

//Config
    //Template Config
    app.engine('handlebars', engine({defaultLayout: 'main'}));
    app.set('view engine', 'handlebars');
    //Body Parser
    app.use(bodyParser.urlencoded({extended: false}));
    app.use(bodyParser.json());

app.listen(3000);

下面是routes.js文件：

const express = require('express');
const routes = express.Router();

const AlunoController = require('../Controller/AlunoController');

//Home page
    routes.get('/', function(req, res){
        res.send('Home page')
    });

// Routes for Aluno's data
    //Final register page
    routes.post('/add-aluno', function(req, res){
        //This is where the error goes
        res.send(`Data sent. Matricula: ${req.body.matricula} ;Nome: ${req.body.nome}; Curso: ${req.body.curso}; Ano: ${req.body.ano}`)
    });
    //Mostrar alunos cadastrados
    routes.get('/show-alunos', function(req, res){
        AlunoController.index
    });
    //Atualizar dados de aluno específico
    routes.put('/upd-aluno/:id', function(req, res){
        AlunoController.put
    });
    //Deletar dados de aluno específico
    routes.delete('/del-aluno/:id', function(req, res){
        AlunoController.delete
    });

    //Rota para formulário de cadastro de alunos
    routes.get('/cad-aluno', function(req, res){
        res.render('formulario')
    });
   

module.exports = routes;

下面是表单.handlebars文件：

<form action="/add-aluno" method="post">
<label>Matrícula: </label>
<br>
<input type="text" name="matricula" placeholder="Ex.: 0001122">
<br>
<label>Nome: </label>
<br>
<input type="text" name="nome" placeholder="Ex.: João Guilherme...">
<br>
<label>Curso: </label>
<br>
<input type="text" name="curso" placeholder="Ex.: Enfermagem">
<br>
<label>Ano: </label>
<br>
<input type="text" name="ano" placeholder="Ex.: 2">
<button type="submit">Enviar</button>
</form>

我不知道我能在这里做什么。主要的错误是在routes.js文件中。在将数据发送到数据库之前，我尝试发送一条消息，显示字段中的4个信息，是这些：入学考试，名，课程，名。但是它什么也没有显示，因为它说它是未定义的。有人能帮忙吗？
