我的 Django 视图如下所示：

#view to retrieve all the exercises
def exercise_all(request):
"""
List all exercises.
"""
if request.method == 'GET':
    exercises = Exercise.objects.all()
    serializer = ExerciseSerializer(exercises, many=True)
    return JSONResponse(serializer.data)


#view to retrieve initial default list of exercises, this will be called on angular controller load
def exercise_initial(request):
"""
Gives the first exercise.
"""
if request.method == 'GET':
    exercises = Exercise.objects.filter(exercise_type=1 , intensity_level=1)
    serializer = ExerciseSerializer(exercises, many=True)
    return JSONResponse(serializer.data)


#view to retrieve all specific exercises
def exercise_next(request, exType, level):
"""
Gives the next exercise.
"""
if request.method == 'GET':
    exercises = Exercise.objects.filter(exercise_type=exType, intensity_level=level)
    serializer = ExerciseSerializer(exercises, many=True)
    return JSONResponse(serializer.data)

我的 url.py：

 url(r'^exercises/all/$', views.exercise_all),
 url(r'^exercises/initial/$', views.exercise_initial),
 url(r'^exercises/(?P<exType>\d)/(?P<level>\d)/$', views.exercise_next),

我调用这些视图的角度控制器：

.controller('videoCtrl', function($scope,$http, $sce, $ionicPopup, djangoAuth) {

$scope.exercise_type='';
$scope.exercise_description='';
$scope.exercise_video_url='';

/**  To fetch the initial exercise **/
$http.get("https://localhost:8000/api/exercises/initial/").then(function(response){

  $scope.initial_data=response.data;

  angular.forEach($scope.initial_data, function(item){

               $scope.exercise_type=item.exercise_type;
               $scope.intensity_level=item.intensity_level;
               $scope.exercise_description=item.description;
                  $scope.exercise_video_url=$sce.trustAsResourceUrl(item.video_url);
           })
});

//Function to play next video
$scope.playNextTest = function(){

  alert("Next exercise: " + ($scope.exercise_type+1)); //demo line, logic needs to be implemented here     
}

我想要达到的目标：

  • 在初始视频控制器加载时，我可以获取分配给 $scope 参数的初始练习详细信息，如代码片段所示。
  • 当我运行 playNextTest() 函数时，我应该能够调用 django view exercise_next 我需要修改我的 url 并附加类似 ../api/exercises/($scope.exercise_type+1)/(($scope.intensity_level )/

如何做到这一点？
