Get Data on conditions by $resource angualrjs

问题

I am using $resource service for my crud operations now i want to get data on a condition like get appointments whose starting date is today. I am fetching all data by

vm.appointments = AppointmentsService.query();

and my service code is

    (function () {
  'use strict';

  angular
    .module('appointments')
    .factory('AppointmentsService', AppointmentsService);

  AppointmentsService.$inject = ['$resource'];

  function AppointmentsService($resource) {
    return $resource('api/appointments/:appointmentId', {
      appointmentId: '@_id'
    }, {
      update: {
        method: 'PUT'
      }
    });
  }
})();

Now can i give condition in this code blockAppointmentsService.query({condition}); or change my service in node rest API. If yes, then what will be my AppointmentsService.query call

For your different url path, you can create new method like below or you can pass startDate as a query string

Controller :

For Path Param

 vm.appointments = AppointmentsService.searchByDate({date:'03/30/2016'});

For Query Param

vm.appointments = AppointmentsService.searchByDate({StartDate:'03/01/2016',EndDate:'03/30/2016'});

Service:

 function AppointmentsService($resource) {
    return $resource('api/appointments/:appointmentId', {
      appointmentId: '@_id'
    }, {
      update: {
        method: 'PUT'
      },
      // For Path Param
      searchByDate :{
        method : 'GET',
        url : 'your url/:date'
      },
     // For Query Param
      searchByDate :{
        method : 'GET',
        url : 'your url/:startDate/:endDate' ,
        params : { startDate : '@StartDate', endDate : '@EndDate' } 
      }
    });
  }

Update your service code...

 (function () {
     'use strict';

  angular
    .module('appointments')
    .factory('AppointmentsService', AppointmentsService);

  AppointmentsService.$inject = ['$resource'];

  function AppointmentsService($resource) {
    var service = {
        get: $resource('api/appointments/:appointmentId',{
           appointmentId: '@_id'
        },{
           method:'GET'
        }),
        update: $resource('api/appointments/:appointmentId',{
           appointmentId: '@_id'
        },{
           method:'PUT'
        }),
        query:$resource('api/appointments',{
           method:'GET',
           isArray:true
        })
        queryByStartDate:$resource('api/appointments/:startDate',{
           startDate: '@_startDate'
        },{
           method:'GET',
           isArray:true
        })
    }
    return service;
   }
})();

And call queryByStartDate inside controller

var startDate = new Date(); //you can use $filter to format date
$scope.appointments = AppointmentsService.queryByStartDate({startDate:startDate});
