mysql - Angular.js put 请求因 Sails.js 和 mysql 数据库而失败

Question

在我的 Angular.js 服务中，我创建了一个自定义请求:

.factory('CalendarService', ['$resource',
          function($resource) {
              return {
                  Update: function(bookingObj) {
                      var BookingResource = $resource('http://localhost:1337/bookings/:id',{
                          id: '@id'
                      }, {
                          'update': {
                              method: 'PUT',
                              isArray: true
                          }
                      });
                      var bookingId = bookingObj.id;
                      return BookingResource.update({
                          id: bookingId
                      }, bookingObj).$promise;
                  }

在服务器端，Sails.js 似乎正确配置了 sails-mysql，我可以毫无错误地发出 get 请求，但是当我调用更新函数时，我收到此错误:

这是来自 Postman 的 HTTP 请求:

{"id":6397,bla bla bla}

这就是我配置 Sails.js 的方式:

1) sails 生成 api 预订

2) npm-install sails-mysql

3) 在 config/connections.js 中插入以下行

mysql: {
    adapter: 'sails-mysql',
    host: 'localhost',
    port: 3306,
    user: 'root',
    password: '',
    database: 'prestige'
  },

4) 添加到 config/cors.js:

allRoutes: true,

methods: 'GET, POST, PUT, DELETE, OPTIONS, HEAD'

origin: '*'

5) 在 config/model.js 添加

module.exports.models = {

  connection: 'mysql',

   migrate: 'safe'

};

sails.js:模型:

module.exports = {

tableName: 'prenotazioni',
adapter: 'mysql',
//migrate: 'safe',
autoCreatedAt: false,
autoUpdatedAt: false,

attributes: {

  id: {
      type: 'integer'

在你的模型中:

module.exports = {
    ...
    autoPK: false,

    attributes: {
        id: {
            type: 'integer',
            autoIncrement: true,
            primaryKey: true
        },
        ...
    }
}
