Question

更新到Sail.js 0.10.1后，我在尝试更新模型的特定实例的属性字段时遇到错误。我也试过做User.find（），然后设置user.attribute = someValue，然后调用user.save（），发生了同样的错误。

以下是相关代码：

// TODO: Save user params (for edit/updates)
save: function(req, res) {
  var params = req.params.all(),
  updateParams = {};

  if (params['publicKey'] != '') {
    sails.log.debug('Updating public key: ' + params['publicKey']);
    updateParams['publicKey'] = params['publicKey'];
  }

  if (params['email'] != '') {
    updateParams['email'] = params['email'];
  }

  sails.log.debug(updateParams);

  User.update({ id: params['id'] }, updateParams, function (err) {
    if (err) sails.log.error(err);

    req.session.messages = { success: ['Successfully updated user profile'] };
    if (req.session.user.admin) {
      return res.redirect('/admin/manage_users');
    } else {
      return res.redirect('/');
    }
  });
},

我得到的错误是：

非常感谢一些指导。

编辑：我正在使用sails-mysql。

编辑：我打开登录本地MySQL数据库并监视正在执行的查询。以下是相关部分：

140804 18:25:19    97 Query SELECT `user`.`id`, `user`.`firstName`, `user`.`lastName`, `user`.`email`, `user`.`registered`, `user`.`admin`, `user`.`publicKey`, `user`.`keyEmail`, `user`.`createdAt`, `user`.`updatedAt` FROM `user` AS `user`  WHERE `user`.`id` = "991426"  LIMIT 1
140804 18:25:41    98 Query SELECT `user`.`id`, `user`.`firstName`, `user`.`lastName`, `user`.`email`, `user`.`registered`, `user`.`admin`, `user`.`publicKey`, `user`.`keyEmail`, `user`.`createdAt`, `user`.`updatedAt` FROM `user` AS `user`  WHERE `user`.`id` = "991426"
       98 Query UPDATE `user` AS `user` SET `publicKey` = 'test2', `email` = '', `updatedAt` = '2014-08-04 18:25:41'  WHERE `user`.`id` = "991426"  ORDER BY `user`.`undefined` DESC
       97 Query SELECT `user`.`id`, `user`.`firstName`, `user`.`lastName`, `user`.`email`, `user`.`registered`, `user`.`admin`, `user`.`publicKey`, `user`.`keyEmail`, `user`.`createdAt`, `user`.`updatedAt` FROM `user` AS `user`

我的用户模型定义为：

// Instance variables
id: {
  type: 'STRING',
  required: true,
  unique: true
},
firstName: {
  type: 'STRING',
  required: true
},
lastName: {
  type: 'STRING',
  required: true
},
email: {
    type: 'STRING',
    email: true,
  unique: true,
},
registered: {
  type: 'BOOLEAN',
  defaultsTo: false
},
admin: {
  type: 'BOOLEAN',
  defaultsTo: false
}, 
publicKey: {
  type: 'TEXT',
  required: true
},
keyEmail: {
  type: 'TEXT',
  email: true,
  required: true
},

// Instance methods
toJSON: function() {
  var obj = this.toObject();
  delete obj._csrf;
  return obj;
}

updateParams：{ publicKey: 'test2', email: '' }

params [＆＃39; id＆＃39;]：991426

Answer 1

我认为这里的问题是你没有为模型设置主键。在primaryKey: true字段上设置id，错误就会消失。谢谢你的报告;如果您没有主键，我们可能会想要修补Waterline以发出警告。而且，你知道，不会崩溃：）

Answer 2

我使用promises和postgres-sails进行了测试，但这对我有用：

User.update(1, {emailAddress: 'test@test.com'}).then(console.log);

唯一的主要区别是我在这里使用Q promises而不是回调。
