Question

我目前正在使用环回工作预约预约应用，下面是我在common / model目录中的预约.js

module.exports = function(Appointment) {


  Appointment.afterCreate = function (next) {
      //TODO add appointment details should not be hardcoded get users email here
      var emailService = require('../../common/services/email.server.service');
      emailService.sendUserEmail('dummy@dummy.com');
      next();
  };

  Appointment.beforeUpdate = function(next) {
      var emailService = require('../../common/services/email.server.service');
      if(this.appointmentStatus === 'waiting_agent'){
          console.log(this.appointmentStatus);
      } else if(this.appointmentStatus === 'waiting_user'){
          console.log(this.appointmentStatus);
      } else {
          console.log(this.appointmentStatus);
      }

      emailService.sendUserEmail('dummy@dummy.com');

      next();

  };
};

afterCreate函数运行良好并发送电子邮件，但是在AfterUpdate / beforeUpdate不起作用之后，我使用Angular作为前端并使用Angular loopback生成服务，下面是更新函数：

function updateAppointment(listingId,newAppointmentInfo,status){
    Appointment.updateAll(
        {
            where:
            {
                listingId : listingId
            }
        },
        {
            "appointmentDate": newAppointmentInfo.selectedDate,
            "appointmentTime" : newAppointmentInfo.selectedTime,
            "appointmentStatus" : status
        },
        function (appointment){
            console.log(appointment);
        },
        function (err){
            console.log(err);
        }
    )
}

是因为我正在调用/约会/更新api而不是更新/约会？

不赞成使用模型钩子来支持操作和每个方法钩子。见http://docs.strongloop.com/display/LB/Operation+hooks

Loopback在模型挂钩触发方面存在一些问题。请参阅问题https://github.com/strongloop/loopback-datasource-juggler/issues/202

loopback模型挂钩无法正常工作
