Question

我有一个问题

有一个模型文件..

模型/ user.js的

module.exports = {

  get: function () {

    //configuration database
    var database=require(""+appDir+"/config/database");

    //sequelize modul
    var Sequelize=require("sequelize");

    //set connection
    var connection = new Sequelize(database.database,database.user,database.password, {
      host: database.host,
      dialect: database.dialect,

      pool: {
        max: 5,
        min: 0,
        idle: 10000
      }
    });

    //table definition
    var User = connection.define('user', {
      firstName: {
        type: Sequelize.STRING
      },
      lastName: {
        type: Sequelize.STRING
      },

      status: {
        type: Sequelize.INTEGER
      }
    });



    //table definition
    var Tasks = connection.define('tasks', {
      taskname: {
        type: Sequelize.STRING
      },

      user_id: {
        type: Sequelize.INTEGER
      }
    });


    User.hasMany(Tasks, {foreignKey: 'user_id'});
    Tasks.belongsTo(User, {foreignKey: 'user_id'});

    return User;


  }
};

使用以下代码; 使用require调用模型文件此代码不包含属性..但不适用于包含属性

//model call
var model=require("../model/user.js");

    model.sync().then(function()
          {
            model.find({include: [Task]}).then(function(user)
            {
              callback(user);
            })
              .catch(function(error)
              {
                callback(error);
              })
          });

但它不起作用..我想加入两个表..

您只导出model / user.js中的get函数，但之后您尝试调用未定义的同步函数。首先，尝试获取用户模型（Sequelize模型），然后调用它的同步功能：

var model = require("../model/user.js");
model.get().sync()

node.js sequelize hasMany关系
