drf the upload file interface

In development, typically upload files to establish a single interface to reduce the coupling process, and more convenient maintenance of late.

urls.py

from django.conf.urls import url, include
from . import views
# 路由组件，必须配合视图集使用
from rest_framework.routers import SimpleRouter
router = SimpleRouter()

# /books/image/(pk) 提交 form-data：用image携带图片
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

# 上传文件 - 修改头像
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
