SequelizeJS传递值的数组

我想弄清楚如何传递一个数组作为实例属性的值。我目前在我的模型中将dataType设置为STRING，并且具有来自jQuery字段的值将每个表单字段值插入到我从身体解析并设置为属性discoverSource的数组中。不幸的是，我收到一个字符串违规错误，说我不能使用数组或对象。这是什么意思，我怎样才能改变字段或路由的dataType，以允许我将逗号分隔值传递给字段？SequelizeJS传递值的数组

E.x.对于discoverySource我将值传递给两个字段（NJ，NY）。上提交，该值被组合在一个数组作为["NJ", "NY"]和错误显示：

错误消息：

{"name":"SequelizeValidationError","message":"string violation: discoverySource cannot be an array or an object","errors":[{"message":"discoverySource cannot be an array or an object","type":"string violation","path":"discoverySource","value":["NJ","NY"]}]}

这是我的模型：

module.exports = function(sequelize, DataTypes) { 

var Organization = sequelize.define('organization', { 
    organizationId: { 
     type: DataTypes.INTEGER, 
     field: 'organization_id', 
     autoIncrement: true, 
     primaryKey: true 
    }, 
    organizationName: { 
     type: DataTypes.STRING, 
     field: 'organization_name' 
    }, 
    admin: DataTypes.STRING, 
    discoverySource: { 
     type: DataTypes.TEXT, 
     field: 'discovery_source' 
    }, 
    members: DataTypes.STRING 
},{ 
    freezeTableName: true, 
    classMethods: { 
     associate: function(db) { 
      Organization.belongsToMany(db.User, { through: 'member', foreignKey: 'user_id' }); 
     }, 
    }, 
}); 
    return Organization; 
}

这里是路线：

var express = require('express'); 
var appRoutes = express.Router(); 
var passport = require('passport'); 
var localStrategy = require('passport-local').Strategy; 
var models = require('../models/db-index'); 

appRoutes.route('/sign-up/organization') 

    .get(function(req, res){ 
     models.User.find({ 
      where: { 
       user_id: req.user.email 
      }, attributes: [ 'user_id', 'email' 
      ] 
     }).then(function(user){ 
      res.render('pages/app/sign-up-organization.hbs',{ 
       user: req.user 
      }); 
     }) 
    }) 

    .post(function(req, res, user){ 
     models.Organization.create({ 
      organizationName: req.body.organizationName, 
      admin: req.body.admin, 
      discoverySource: req.body.discoverySource 
     }).then(function(organization, user){ 
      res.redirect('/app'); 
     }).catch(function(error){ 
      res.send(error); 
      console.log('Error at Post' + error); 
     }) 
    });

这是我的观点文件：

<!DOCTYPE html> 
<head> 
    {{> head}} 
</head> 
<body> 
    {{> navigation}} 
    <div class="container"> 
     <div class="col-md-6 col-md-offset-3"> 
      <form action="/app/sign-up/organization" method="post"> 
       <p>{{user.email}}</p> 
       <input type="hidden" name="admin" value="{{user.email}}"> 
       <input type="hidden" name="organizationId"> 
       <label for="sign-up-organization">Company/Organization Name</label> 
       <input type="text" class="form-control" id="sign-up-organization" name="organizationName" value="" placeholder="Company/Organization"> 
       <a href="#" id="sign-up-add-discovery-source">Add Another Discovery Source</a> 
       <div id="sign-up-organization-discovery-source"> 
        <input type="text" id="discovery-source-field" placeholder="Discovery Source" name="discoverySource[0]"> 
       </div> 
       <br /> 
        <button type="submit">Submit</button> 
      </form> 
      <a href="/login">Already have an account? Login here!</a> 
     </div> 
    </div> 
    <script type="text/javascript"> 
     $(function() { 
    var dataSourceField = $('#sign-up-organization-discovery-source'); 
    var i = $('#sign-up-organization-discovery-source p').size(); 
    var sourceCounter = 1; 

    $('#sign-up-add-discovery-source').on('click', function() { 
    $('<p><label for="discovery-source-field"><input type="text" id="discovery-source-field" size="20" name="discoverySource['+ sourceCounter++ +']" value="" placeholder="Discovery Source" /></label> <a href="#" class="remove">Remove</a></p>').appendTo(dataSourceField); 
    i++; 
    return false; 
    }); 
    $('#sign-up-organization-discovery-source').on('click', '.remove', function() { 
    if (i > 1) { 
     $(this).parent('p').remove(); 
     i--; 
    } 
    return false; 
    }); 
}); 

    </script> 
</body>

要回答最后一条评论，我需要能够使代码更具可读性，所以我在这里发布一个新的答案。

多想了一会，将它作为自定义的“getter”函数添加会更有意义。我还将包括'instanceMethods'来演示如何工作。

var Organization = sequelize.define('organization', { 
    ... 
},{ 
    freezeTableName: true, 
    classMethods: { 
     associate: function(db) { 
      Organization.belongsToMany(db.User, { through: 'member', foreignKey: 'user_id' }); 
     }, 
    }, 
    // Here's where custom getters would go 
    getterMethods: { 
     discoverySources: function() { 
      return this.getDataValue('discoverySource'); 
     } 
    }, 
    // here's the instance methods 
    instanceMethods: { 
     getSourcesArray: function() { 
      return this.getDataValue('discoverySource'); 
     } 
    } 
});

这两个选项都将函数添加到模型创建的每个实例。主要区别在于如何访问它们。

organization.discoverySources; // -> ['s1', 's2', etc...] 
organization.getSourcesArray(); // -> ['s1', 's2', etc...]

注意instanceMethod上需要额外的()。这些作为实例的函数添加，getterMethods get作为属性添加。

setterMethods以同样的方式工作，允许您定义自定义设置器。

希望澄清一些事情。
