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似乎使用sails-mysql正确配置，我可以发出没有错误的get请求，但是当我调用更新函数时，我收到此错误：

这是邮递员的HTTP请求：

{"id":6397,bla bla bla}

这是我配置Sails.js的方式：

1）帆生成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上添加了

module.exports.models = {

  connection: 'mysql',

   migrate: 'safe'

};

sails.js：model：

module.exports = {

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

attributes: {

  id: {
      type: 'integer'

在你的模特中：

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

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