drf之上傳文件接口

在開發中，一般為上傳文件單獨設立一個接口，以降低程序的耦合度，並且更方便后期的維護。

urls.py

from django.conf.urls import url, include
from . import views
# 路由組件，必須配合視圖集使用
from rest_framework.routers import SimpleRouter
router = SimpleRouter()

# /books/image/(pk) 提交 form-data：用image攜帶圖片
router.register('books/image', views.BookUpdateImageAPIView, 'book')

urlpatterns = [
    url('', include(router.urls))
]

serializers.py

class BookUpdateImageModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Book
        fields = ['image']

views.py

# 上傳文件 - 修改頭像
from rest_framework.viewsets import GenericViewSet
from rest_framework import mixins
class BookUpdateImageAPIView(GenericViewSet, mixins.UpdateModelMixin):
    queryset = models.Book.objects.filter(is_delete=False).all()
    serializer_class = serializers.BookUpdateImageModelSerializer
