Question

我有django模型，它的视图定义为：

from generic_relations.relations import GenericRelatedField
from rest_framework import serializers
from notes.models import Note

from leads.models import Lead
from leads.serializers import LeadSerializer

from callbacks.models import Callback
from callbacks.serializers import CallbackSerializer


class NoteSerializer(serializers.ModelSerializer):
    """
    A `Note` serializer with a `GenericRelatedField` mapping all possible
    models to their respective serializers.
    """
    note_object = GenericRelatedField({
        Lead: LeadSerializer(),
        Callback: CallbackSerializer()
    })

    class Meta:
        model = Note
        fields = (
            'id',
            'author',
            'title',
            'text',
            'created_date',
            'note_object',
            )

如何将主键作为响应返回？这就是我的Json在发布请求后的样子：

class ItemViewSet(viewsets.ModelViewSet):

queryset = Item.objects.all()
serializer_class = ItemSerializer

我的回答应该是：4即主键 `class ItemSerializer（serializers.ModelSerializer）：

{
        "id": 4,
        "UID": "465666700",
        "name": "rohit ",
        "gender": "MALE",
        "yob": "1996"
    }

帮助感谢。

Answer 1

为Item模型声明ModelSerializer。将字段属性设置为[＆＃39; id＆＃39;]，这应该有效！

class ItemSerializer(serializers.ModelSerializer):
    model = Item
    fields = ['id']

Answer 2

只需在id中添加ItemSerializer，例如：

from rest_framework import serializers

class ItemSerializer(serializers.Serializer):
    id = serializers.IntegerField(source='pk')

当我们使用django rest框架发出帖子请求时，如何将主键作为响应返回？
