Django REST框架：从字符串创建JSON片段

Question

我想使用JSON将JSON片段存储在模型的TextField中：

class A(models.Model):
    name = models.CharField(max_length=200)
    people = models.TextField()

我有序列化程序类：

class ASerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = A
        fields = ('name', 'people')

我如何告诉Django REST Framework将人字符串像JSON一样对待，而不是像字符串一样。例如，当人们是我希望在Django REST框架生成的JSON中具有[{“ name”：“ A”，“ surname”：“ B”}]时

"people" : [ {"name":"A", "surname":"B"}]

并不是

"people" : "[ {\"name\":\"A\", \"surname\":\"B\"}]"

---

编辑：我更改了ASerializer类，并从django-jsonfield使用了JSONField，并且一切正常。下面的新代码transform_people方法用于序列化，validate_people用于反序列化：

class ASerializer(serializers.ModelSerializer):
    def transform_people(self, obj, value):
        if obj is None:
            return obj
        else:
            return obj.people

    def validate_people(self, attrs, source):
        return attrs

    class Meta:
        model = A

将您的响应转换为 json 对象

import json
## In this case lets say
response = [{"name":"A", "surname":"B"}]
data = json.dumps(response)
print data
