MIS系统（6）- 商品管理之SPU管理

博客首页 > MIS专栏> 专栏目录

界面管理：

1,spu表数据获取

• 目的:可以将spu表的信息,展示在页面中

• 操作流程:

  • 1, 子路由(meiduo_admin/urls.py)

    • #4,spu管理
      router = DefaultRouter()
      router.register(r'goods',spu_views.SPUViewSet,base_name="goods")
      urlpatterns += router.urls
      
      

  • 2,类视图(good/spu_views.py)

    • #1,spu管理
      class SPUViewSet(ModelViewSet):
          pagination_class = MyPageNumberPagination
          serializer_class = spu_serializers.SPUSerializer
          queryset = SPU.objects.all()
      

  • 3,序列化器(spu_serializers.py)

    • #1,spu序列化器
      class SPUSerializer(serializers.ModelSerializer):
      
          #1,重写brand
          brand = serializers.StringRelatedField(read_only=True)
          brand_id = serializers.IntegerField()
      
          #2,重写分类
          category1 = serializers.StringRelatedField(read_only=True)
          category1_id = serializers.IntegerField()
      
          category2 = serializers.StringRelatedField(read_only=True)
          category2_id = serializers.IntegerField()
      
          category3 = serializers.StringRelatedField(read_only=True)
          category3_id = serializers.IntegerField()
      
          class Meta:
              model = SPU
              fields = "__all__"
      

2,spu表获取品牌信息

• 目的:可以在添加spu的时候,获取品牌信息

• 操作流程:

  • 1, 子路由(meiduo_admin/urls.py)

    • url(r'^goods/brands/simple/$',spu_views.SPUBrandSimpleView.as_view())
      

  • 2,类视图(good/spu_views.py)

    • #2,spu,brand品牌获取
      class SPUBrandSimpleView(ListAPIView):
          serializer_class = spu_serializers.SPUBrandSimpleSerializer
          queryset = Brand.objects.all()
      

  • 3,序列化器(good/spu_serializers.py)

    • #2,spu,brand序列化器
      class SPUBrandSimpleSerializer(serializers.ModelSerializer):
          class Meta:
              model = Brand
              fields = ("id","name")
      
      

3,spu表获取一级分类信息

• 目的:可以将一级分类,展示在添加spu的页面中

• 操作流程:

  • 1, 子路由(meiduo_admin/urls.py)

    • url(r'^goods/channel/categories/$',spu_views.SPUCategoryView.as_view()),
      

  • 2,类视图(good/spu_views.py)

    • #3,spu,category分类获取
      class SPUCategoryView(ListAPIView):
          serializer_class = spu_serializers.SPUCategorySerializer
          queryset = GoodsCategory.objects.filter(parent__isnull=True)
      

  • 3,序列化器(good/spu_serializers.py)

    • #3,spu,category序列化器
      class SPUCategorySerializer(serializers.ModelSerializer):
          class Meta:
              model = GoodsCategory
              fields = ("id","name")
      

4,spu表获取二级和三级分类

• 目的:可以选中父级之后,查询对应的子集数据

• 操作流程:

  • 1, 子路由(meiduo_admin/urls.py)

    • url(r'^goods/channel/categories/(?P\d+)/$',spu_views.SPUSubsCategoryView.as_view()),
      

  • 2,类视图(good/spu_views.py)

    • #4,spu,二级分类,三级分类
      class SPUSubsCategoryView(ListAPIView):
          serializer_class = spu_serializers.SPUCategorySerializer
      
          def get_queryset(self):
              category_id = self.kwargs.get("category_id")
              queryset = GoodsCategory.objects.filter(parent_id=category_id).all()
              return queryset
      

5,调试fdfs上传图片

• 目的:可以通过终端,调试fdfs上传图片

  • 1, 将client文件添加到utils中

  • 2,终端调试

    • In [1]: from fdfs_client.client import Fdfs_client                                                                                                                 
      
      In [2]: #1,创建对象                                                                                                                                                
      
      In [3]: client = Fdfs_client('/Users/heJing/Desktop/classes2/day19/meiduo14/meiduo_mall/meiduo_mall/utils/fdfs/client.conf')                                       
      
      In [4]: #2,上传图片                                                                                                                                                
      
      In [5]: client.upload_by_filename("/Users/heJing/Desktop/上课资料2/day19/3_资料/测试图片/haha.jpg")                                                                
      getting connection
      <fdfs_client.connection.Connection object at 0x10f8459e8>
      <fdfs_client.fdfs_protol.Tracker_header object at 0x10f845710>
      Out[5]: 
      {'Group name': 'group1',
       'Remote file_id': 'group1/M00/00/03/rBAMhl11zCyAfqwPAACP4XconFQ208.jpg',
       'Status': 'Upload successed.',
       'Local file name': '/Users/heJing/Desktop/上课资料2/day19/3_资料/测试图片/haha.jpg',
       'Uploaded size': '35.00KB',
       'Storage IP': '172.16.12.134'}
      
      

6,spu表上传图片

• 目的: 可以通过fdfs上传添加spu的图片

• 操作流程:

  • 1, 子路由(meiduo_admin/urls.py)

    • url(r'^goods/images/$',spu_views.SPUImageUploadView.as_view()),
      

  • 2,类视图(good/spu_views.py)

    • #5,spu,image上传
      class SPUImageUploadView(APIView):
      
          def post(self,request):
              #1,获取参数
              image = request.FILES.get("image")
      
              #2,校验参数
              if not image:
                  return Response(status=400)
      
              #3,数据入库(fdfs)
              #3,1 上传图片
              client = Fdfs_client(settings.BASE_CONFIG)
              result = client.upload_by_buffer(image.read())
      
              #3,2 判断图片是否上传成功
              if result.get("Status") != "Upload successed.":
                  return Response(status=400)
      
              image_url = result.get("Remote file_id")
      
              #4,返回响应
              return Response({
                  "img_url":"%s%s"%(settings.BASE_URL,image_url)
              })
      

7,spu表数据保存，更新，删除

• 注意点: 由于使用的是视图集完成的SPU的管理,所以已经实现了
