python - 如何使用 DRF3 获取 Django 中的整个 JSON 对象？

Question

当我调用 API (curl) 时，我得到以下信息:

{"id": 1, "name": "Sword", "persona": [1]}

我得到了角色的“id”，但没有得到其中的属性。我该怎么做？

模型.py:

class Persona(models.Model):
    name = models.CharField(max_length=255)
    description = models.CharField(max_length=255)
    icon = models.CharField(max_length=255,default='1')

    def __str__(self):
        return self.name

class Equipment(models.Model):
    personas = models.ManyToManyField(Persona)
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name

序列化器.py:

class EquipmentSerializer(serializers.ModelSerializer):
    personas = serializers.PrimaryKeyRelatedField(queryset=Persona.objects.all(), many=True)
    name = serializers.CharField(max_length=255)

    class Meta:
        model = Equipment
        fields = ('id', 'name', 'persona')

Answer 1

您需要两个步骤:

1. 创建一个 Persona 序列化器类:

   class PersonaSerializer(serializers.ModelSerializer):
       class Meta:
           model = Persona
   

2. 然后您可以将此序列化器“链接”到设备序列化器:

   class EquipmentSerializer(serializers.ModelSerializer):
       personas = PersonaSerializer(source='personas', many=True)
       name = serializers.CharField(max_length=255)
   
       class Meta:
           model = Equipment
           fields = ('id', 'name', 'personas')
