node.js - Sequelizejs 未显示所有验证错误或消息

Question

这是我的 models.js

var User = require('../../managedb').User;

module.exports = function(sequelize, DataTypes) {


  return sequelize.define('User', {
    username: {
      type: DataTypes.STRING,
      unique: {
        msg: "Username already exists!"
      }
    },
    password: {
      type: DataTypes.STRING,
      len: {
        args: 6,
        msg: "Password must be atleast 6 characters in length"
      }
    },
    email_id:{
      type: DataTypes.STRING,
      unique:{
        msg: "Email already exists!"
      },
      validate: {
        isEmail: {
          msg: "Email is invalid!"
        },
        notNull: true,
      }
    },
    id: {
      type: DataTypes.INTEGER,
      primaryKey: true,
      autoIncrement: true
    }
  },
    {
    instanceMethods: {
      countTasks: function() {
        // how to implement this method ?
      }
    }
  });

这是当我尝试使用非唯一用户名和电子邮件保存对象时收到的错误响应:

'{"length":173,"name":"error","severity":"ERROR","code":"23505","detail":"Key (email_id)=(yup2@gmail.com) already exists.","file":"nbtinsert.c","line":"397","routine":"_bt_check_unique"}'

我必须先运行 validate() 函数吗？我哪里出错了？

验证必须是属性定义中 validate 对象的一部分:

return sequelize.define('User', {
  username: {
    type: DataTypes.STRING,
    validate: {
      unique: {
        msg: "Username already exists!"
      }
    }
  }
})
