如何在nodejs中使用sequelize设置模型验证？

Question

我是 nodejs 的新手。我已经为 nodejs orm 使用了 sequelize。但是我无法将验证设置为属性；

models/farmer.js

'use strict';
module.exports = function(sequelize, DataTypes) {
  var Farmer = sequelize.define('Farmer', {
    username:{
            type: DataTypes.STRING,
            allowNull: false,
    },
    address: DataTypes.STRING,
    email: {
        type: DataTypes.STRING,
        validate: {
           isEmail: true
        }
    },
    phone:{
            type: DataTypes.STRING,
            allowNull: false,
    },
  }, {
    classMethods: {
      associate: function(models) {
          Farmer.hasMany(models.Task);
        // associations can be defined here
      }
    }
  });
  return Farmer;
};

错误：

如何设置验证模型？

Answer 1

这个：

Possibly unhandled SequelizeValidationError: Validation error at

表示您的续集验证有效。它检查验证并在验证失败时抛出错误 (SequelizeValidationError)。

但是这个 :

Possibly unhandled

表示您对此错误不做任何处理。你应该捕获这个错误并做一些事情（例如发送带有适当错误代码的响应）。

例如，当您创建新的 'Farmer' 时，您的代码可能如下所示：

Farmer.create({
  //your data
}).then(function(){
  //do something when Farmer is created
}).catch(function(err){
  //do something when you get error
  //you could check if this is validation error or other error
});

有时在 sequelize 之外验证错误是个好主意（但不要在 sequelize 中删除验证，让两个验证一起工作）（我写了一些参数）。
