Question

当我调用我的API（curl）时，我得到以下内容：

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

我正在获得＆＃39; id＆＃39;角色，但不是内在的属性。我该怎么做？

Models.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

Serializers.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：

创建Persona serializer class：

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

然后您可以将此序列化程序“链接”到Equipement一个：

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

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