Question

我只是在尝试使用sails.js更新'bookings'mysql字段时才收到错误。这是预订模型：

module.exports = {

    tableName: 'bookings',
    adapter: 'mysql',
    autoCreatedAt: true,
    autoUpdatedAt: true,

  attributes: {

      id: {type: 'integer',autoIncrement: true,primaryKey: true},
      booking_n: {type: 'integer'},
      customer: { model:'customers'},
      room: {type: 'string'},
      departure: {type: 'date'},
      createdAt: {type: 'date'},
      updatedAt: {type: 'date'},
      invoice: {mode:'invoices'}
    }
};

正如您所看到的，有2个“一对多”关联，（发票可以有多个预订等），这里是发票模型：

module.exports = {

    tableName:'invoices',
    adapter: 'mysql',
    autoPK:false,
    autoCreatedAt: true,
    autoUpdatedAt: true,

attributes: {

id: {type: 'integer', autoIncrement: true, primaryKey: true},
doc_mod: {type:'string'},
doc_n: {type:'integer'},
createdAt: {type:'date'},
updatedAt: {type:'date'},
invoice_line: {collection:'invoice_lines', via:'invoice'},
customer: {model:'customers'},
bookings:{collection:'bookings', via:'invoice'}
  }
}

来自Angular我想用新invoice.id：

更新预订模型

Update:function(bookingObj){

    var BookingResource = $resource(IP_ADDRESSES.dbserver+'bookings/:id',{
        id: '@id'
    },{
        'update': {
            method: 'PUT'
        }
     });
    return BookingResource.update({id: bookingObj.id}, bookingObj).$promise;
}

但是我从sails控制台日志中得到了这个错误：

来自Postman的

我可以看到客户端正在发送这个对象：

Answer 1

我发现了自己的错误：正如我之前的评论中所提到的，错误是指错误的模型关联，在我的情况下由于拼写错误：我写了"C:\\opencv2.4.9\\sources\\data\\haarcascades\\haarcascade_frontalface_alt.xml"，而不是invoice: {mode:'invoices'}。< / p>
