如何在模板中使用django-rest-framework

Question

请多多包涵.我只是在学习django-rest-framework.我真的无法抓住它.

模型:

class Day(models.Model):
    date = models.DateField(default=date.today)

class ToDo(models.Model):
    date = models.ForeignKey(Day)
    name = models.CharField(max_length=100)
    very_important = models.BooleanField(default=False)
    finished = models.BooleanField(default=False)

正常观点:

def home(request):
    days = Day.objects.all()

    return render(request, 'test.html', {
        'days':days
    })

创建了一个serializers.py文件:

class DaySerializer(serializers.ModelSerializer):
    class Meta:
        model = Day
        field = ('id', 'date')


class ToDoSerializer(serializers.ModelSerializer):
    date = DaySerializer()
    class Meta:
        model = ToDo
        field = ('id', 'date', 'name', 'very_important', 'finished')

在此之后,我迷失了.假设我去了url('^api/$'),如何获取Day及其相关对象的json对象？

基本上这就是我想要显示的方式:

现在我如何使用django-rest-framework看起来像模板中的上述内容.

更新

我想做这样的事情:

1. 通过转到url获取json对象(例如:/api/.json)

   [
       {
           "id": 1,
           "date": "2015-06-23",
           "day_todo_set": [
               {
                   "id":5
                   "name": "Bloom",
                   "very_important": True,
                   "finished": False
               },
               {
                   "id":4
                   "name": "REST",
                   "very_important": True,
                   "finished": True
               }
           ]
       },
       {
           "id": 2,
           "date": "2015-06-22",
           "day_todo_set": [
               {
                   "id":3
                   "name": "Alarm 1",
                   "very_important": True,
                   "finished": True
               },
               {
                   "id":2
                   "name": "Meet up with SIS",
                   "very_important": True,
                   "finished": False
               },
               {
                   "id":1
                   "name": "Buy Milk",
                   "very_important": True,
                   "finished": False
               }
           ]
       }
   ]
   

2. 操纵对象

JS:

$(function () {
    var $days = $('#days')

    $.ajax({
        type: 'GET',
        url: '/api/.json',
        success: function(days) {
            $.each(days, function(i, day) {
                $days.append('<li>date: '+ day.date+ '</li>')
            });
        }
    });
})

Answer 1

model.py:

class Day(models.Model):
    date = models.DateField(default=date.today)

    def get_todo_list(self):
        return self.day_todo_set.order_by('-id')[:5] 

class ToDo(models.Model):
    date = models.ForeignKey(Day, related_name="day_todo_set")
    name = models.CharField(max_length=100)
    very_important = models.BooleanField(default=False)
    finished = models.BooleanField(default=False)

在serializers.py中

class ToDoSerializer(serializers.ModelSerializer):

    class Meta:
        model = ToDo
        field = ('id', 'date', 'name', 'very_important', 'finished')

class DaySerializer(serializers.ModelSerializer):

    day_todo_set = ToDoSerializer(many=True, source="get_todo_list")

    class Meta:
       model = Day
       field = ('id', 'date', 'day_todo_set')

使用序列化程序编写django视图.

@csrf_exempt
def day_list(request):
    """
    List all code snippets, or create a new snippet.
    """
    if request.method == 'GET':
        snippets = Day.objects.order_by('-date')[:10]
        serializer = DaySerializer(snippets, many=True)
        return JSONResponse(serializer.data)

在你的urls.py中

url(r'^api/$', views.day_list, name='days_list')
