val.replace不是一个函数 - Sequelize

Question

我每次执行下面的代码时都会遇到此错误，我似乎无法弄清楚

  

未处理拒绝TypeError：val.replace不是函数       在Object.SqlString.escape

var connection = new Sequelize('database', 'root', 'phase_99');

var User = connection.define('user', {title: Sequelize.STRING});
var Project = connection.define('project', {title: Sequelize.STRING});



User.hasMany(Project);
Project.belongsTo(User);

connection.sync().then(() => {
User.create({title: 'user'})
  .then(user => {
    var project = Project.create({title: 'ISD Corp'});
    user.addProject({project});
  })
});

Answer 1

您正在创建产品之前添加产品，因为这是一个承诺执行此操作

User.create({title: 'user'})
  .then(user => {
    Project.create({title: 'ISD Corp'}).then(project => {
       user.addProject({project});
    })
  })
});
