json - 如何在模板中使用 django-rest-framework

Question

请多多包涵。我刚学习django-rest-framework .我似乎真的无法捕获它。

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)

普通 View :

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')

在这之后我迷路了。假设我去 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的显示方式:



现在我如何使用 django-rest-framework 在模板中看起来像上面那样。

更新

我想做这样的事情:

通过访问 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
            }
        ]
    }
]

操作对象

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>')
            });
        }
    });
})

模型.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 View 。

@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

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