Javascript Sequelize创建一对多，而不是一对一

我正在创建菜单和菜单URL表之间的一对一关系，但它在sequelize nodejs应用程序中创建一对多关系

我试过：

db.menu\u url.belongsTo（db.menu，{foreignKey:'menu\u id'}）

db.menu.hasOne（db.menu\uURL，{foreignKey:'menu\uid'}）

甚至尝试在模型定义中创建外键

但在所有的一对多不动产中都已建立

菜单\u url.js

module.exports = (sequelize,DataTypes) => {
    const menu_urls= sequelize.define("menu_urls",{
        url_id: {
            type:DataTypes.INTEGER(4),
            primaryKey: true
        }
        menu_id: {
            type: DataTypes.INTEGER(3),
            unique: true
        }
    });

    return menu_urls;
}

module.exports = (sequelize, DataTypes) => {
    const menus = sequelize.define("menus", {
      menu_id: {
        type: DataTypes.INTEGER(3),
        primaryKey: true,
        autoIncrement: true,
      },
      menu_name: {
        type: DataTypes.STRING(20),
        allowNull: false  
      }
    });

    return menus;
};

var db        = {};
fs.readdirSync(__dirname)
  .filter(file => file.indexOf(".") !== 0 && file !== "index.js")
  .forEach(file => {
    const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
    db[model.name] = model;
  });

db.menu_urls.belongsTo(db.menus,{foreignKey: 'menu_id'});

sequelize.sync({
  force : true,
  logging : console.log
}).then(function () {
  console.log('Database Connected!!');
}).catch(function (err) {
  console.log(err, "Something went wrong with the Database Connection!")
});

menus.js

module.exports = (sequelize,DataTypes) => {
    const menu_urls= sequelize.define("menu_urls",{
        url_id: {
            type:DataTypes.INTEGER(4),

            type: DataTypes.INTEGER(3),
            unique: true
        }
    });

    return menu_urls;
}

module.exports = (sequelize, DataTypes) => {
    const menus = sequelize.define("menus", {
      menu_id: {
        type: DataTypes.INTEGER(3),
        primaryKey: true,
        autoIncrement: true,
      },
      menu_name: {
        type: DataTypes.STRING(20),
        allowNull: false  
      }
    });

    return menus;
};

var db        = {};

  .forEach(file => {
    const model = require(path.join(__dirname, file))(sequelize, Sequelize.DataTypes);
    db[model.name] = model;
  });

db.menu_urls.belongsTo(db.menus,{foreignKey: 'menu_id'});

sequelize.sync({
  force : true,
  logging : console.log
}).then(function () {
  console.log('Database Connected!!');
}).catch(function (err) {
  console.log(err, "Something went wrong with the Database Connection!")
});

index.js

module.exports = (sequelize,DataTypes) => {
    const menu_urls= sequelize.define("menu_urls",{
        url_id: {
            type:DataTypes.INTEGER(4),

            type: DataTypes.INTEGER(3),
            unique: true
        }
    });

    return menu_urls;
