python - 是否可以将 django View 集与两个序列化器一起使用？

Question

我有一个 Articles 的模型其中有很多字段。当有人通过 id 获取特定文章时我想将几乎所有字段发送回客户端。

但是，当生成文章列表时，我不想发送包含所有数据的所有文章，而是将每篇文章限制为几个重要的列表字段，并放弃像 content 这样的长字段。等等..

我可以通过对 django_restframework.viewsets 进行优雅的调整来实现这些目标吗？模块，或者我应该使用 django_restframwork.generics 自己构建 api 方法相反？

示例:

# articles/api/urls.py #
# -------------------- #

from articles.api.views import ArticlesViewSet
from django.urls import path
from rest_framework.routers import DefaultRouter

router = DefaultRouter()
router.register(r'', ArticlesViewSet, basename='articles')
urlpatterns = router.urls

# articles/api/views.py #
# --------------------- #
from rest_framework.viewsets import ModelViewSet

from ..models import Article
from .serializers import ArticleSerializerFull, ArticleSerializerShort


class ArticlesViewSet(ModelViewSet):
    # Perhaps some conditional code here?
    serializer_class = ArticleSerializerFull
    queryset = Article.objects.all()

Answer 1

您可以使用DRF中的get_serializer_class()方法来解决该问题...

序列化器.py

class ArticleFullSerializer(serializers.ModelSerializer):

    class Meta:
        model = Order
        fields = ('__all__')

class ArticleShortSerializer(serializers.ModelSerializer):

    class Meta:
        model = Order
        fields = ('field1', 'field2' ... 'fieldn')

views.py

from rest_framework.viewsets import ModelViewSet


class ArticleViewSet(ModelViewSet):
    serializer_class = ArticleSerializerFull
    queryset = Article.objects.all()

    def get_serializer_class(self):
        if self.action == 'list':
            serializer = ArticleShortSerializer
        else:
            serializer = ArticleFullSerializer
        return serializer
