请多多包涵.我刚刚学习
django-rest-framework.而且我似乎无法抓住它.
@H_404_2@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)
@H_404_2@正常观点：
def home(request):
days = Day.objects.all()
return render(request,'test.html',{
'days':days
})
@H_404_2@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')
@H_404_2@在此之后,我迷失了.假设我转到url(‘^ api / $’),如何获取Day及其相关对象的json对象？
@H_404_2@基本上这就是我想要显示的方式：
@H_404_2@现在我如何使用django-rest-framework看起来像模板中的上述内容.
@H_404_2@更新
@H_404_2@我想做这样的事情：
@H_404_2@>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","finished": True
}
]
},{
"id": 2,"date": "2015-06-22","day_todo_set": [
{
"id":3
"name": "Alarm 1","finished": True
},{
"id":2
"name": "Meet up with SIS",{
"id":1
"name": "Buy Milk","finished": False
}
]
}
]
@H_404_2@>操纵对象
@H_404_2@JS：
$(function () {
var $days = $('#days')
$.ajax({
type: 'GET',url: '/api/.json',success: function(days) {
$.each(days,function(i,day) {
$days.append('<li>date: '+ day.date+ '</li>')
});
}
});
})
解决方法
model.py：
class Day(models.Model):
date = models.DateField(default=date.today)
def get_todo_list(self):
return self.day_todo_set.order_by('-id')[:5]
class ToDo(models.Model):
date = models.ForeignKey(Day,related_name="day_todo_set")
name = models.CharField(max_length=100)
very_important = models.BooleanField(default=False)
finished = models.BooleanField(default=False)
@H_404_2@在serializers.py中
class ToDoSerializer(serializers.ModelSerializer):
class Meta:
model = ToDo
field = ('id','finished')
class DaySerializer(serializers.ModelSerializer):
day_todo_set = ToDoSerializer(many=True,source="get_todo_list")
class Meta:
model = Day
field = ('id','day_todo_set')
@H_404_2@使用序列化程序编写django视图.
@csrf_exempt
def day_list(request):
"""
List all code snippets,or create a new snippet.
"""
if request.method == 'GET':
snippets = Day.objects.order_by('-date')[:10]
serializer = DaySerializer(snippets,many=True)
return JSONResponse(serializer.data)
@H_404_2@在你的urls.py中
url(r'^api/$',views.day_list,name='days_list')
