Question

我有3个序列化器：

class abcSerializer(serializers.ModelSerializer):
    created=Field(source='time')
    result = Field(source='result')

    class Meta:
        model = abc
        fields = ('created','result')
        order_by = ['-created']

class defSerializer(serializers.ModelSerializer):
    created=Field(source='time')
    result = Field(source='result')
    class Meta:
        model = def
        fields =('created','result')
        order_by = ['-created']



class mainSerializer(serializers.ModelSerializer):
    obj1 = abcSerializer()
    obj2 = defSerializer()

    class Meta:
        model = main

        fields = ('obj1','obj2')

在views.py中：

data =  main.objects.filter(id=111)
serializer = mainSerializer(data)
return Response(record)

在UI中，我正在显示序列化数据，如下所示：

        created                result
abc     1-9-2016 9:30:00        pass

def     2-9-2016 10:34:00       fail

我收到的序列化数据如下：

data = [{'created':'1-09-2106','result':'pass'},{'created':'2-09-2106','result':'fail'}]

我想根据最新日期 创建字段对数据进行排序。

created result def 2-9-2016 9:30:00 fail abc 1-9-2016 10:34:00 pass

无法弄清楚如何对创建的字段进行排序任何帮助将不胜感激!!

我认为您希望在模型中使用order而不是序列化器。

class abcModel(models.Model):
    created = models.DateTimeField(...)
    result = ...

    class Meta:
        ordering = ['-created']

Django：在序列化数据上应用订单
