Question

我想了解在什么级别编写代码来控制django序列化程序返回的顺序。必须在模板级别，模型级别或序列化程序级别完成。是什么决定了任何序列化程序返回的JSON中的字段顺序？在我的示例中，考虑这些序列化程序类：

class FilterURLSerializer(serializers.Serializer):
    active = serializers.CharField(read_only=True)
    inactive = serializers.CharField(read_only=True)


class FacetedFilterOptionsSerializer(serializers.Serializer):
    name = serializers.CharField(read_only=True)
    slug = serializers.CharField(read_only=True)
    count = serializers.IntegerField(read_only=True)
    active = serializers.BooleanField(read_only=True)
    urls = FilterURLSerializer(read_only=True)


class FacetedFilterSerializer(serializers.Serializer):
    name = serializers.CharField(read_only=True)
    slug = serializers.CharField(read_only=True)
    options = FacetedFilterOptionsSerializer(source='options')

并返回此JSON数据：

{'name': u'Skill level', 'slug': u'skill', 'options': [{'name': u"I'm Learning", 'slug': u'beginner', 'count': 0, 'active': False, 'urls': {'active': u'/en-US/search?skill=beginner', 'inactive': u'/en-US/search'}}, {'name': u"I'm an Expert", 'slug': u'advanced', 'count': 0, 'active': False, 'urls': {'active': u'/en-US/search?skill=advanced', 'inactive': u'/en-US/search'}}, {'name': u'Intermediate', 'slug': u'intermediate', 'count': 0, 'active': False, 'urls': {'active': u'/en-US/search?skill=intermediate', 'inactive': u'/en-US/search'}}]}

我想知道是什么决定了JSON中这些字段的顺序，我该如何以我想要的方式更改它？

如果您想要订购字段名称，可以尝试以下方法：

myList = list(yourmodel.objects.values('filed1','field2').filter(someid=i).orderby('column'))
