MIS系统（9）- 商品管理之频道管理

博客首页 > MIS专栏> 专栏目录

界面展示：

1 获取所有频道

• 1，配置路由(meiduo_admin/urls.py)

  • # 12.channel 管理
    router = DefaultRouter()
    router.register(r'goods/channels', channel_views.ChannelViewSet, base_name="channels")
    urlpatterns += router.urls
    

• 2，添加视图(meiduo_admin/good/channel_views.py)

  • from rest_framework.viewsets import ModelViewSet
    from meiduo_admin.good import channel_serializers
    from meiduo_admin.my_paginate import MyPageNumberPagination
    from goods.models import GoodsChannel
    
    
    # 1,获取所有频道
    class ChannelViewSet(ModelViewSet):
        pagination_class = MyPageNumberPagination
        serializer_class = channel_serializers.ChannelSerializer
        queryset = GoodsChannel.objects.all()
    

• 3，定义序列化器(meiduo_admin/good/channel_serializers)

  • from rest_framework import serializers
    from goods.models import GoodsChannel
    
    
    # 1,channel序列化器
    class ChannelSerializer(serializers.ModelSerializer):
        # group,group_id
        group = serializers.StringRelatedField(read_only=True)
        group_id = serializers.IntegerField()
    
        # category,category_id
        category = serializers.StringRelatedField(read_only=True)
        category_id = serializers.IntegerField()
    
        class Meta:
            model = GoodsChannel
            fields = '__all__'
    
    

2 获取频道组和一级分类

• 1，配置路由

  •     # 12,channel管理
        url(r'^goods/channel_types/$', channel_views.ChannelTypesView.as_view()),
        url(r'^goods/categories/$', channel_views.ChannelCategoriesView.as_view()),
    

• 2，添加视图

  • # 2,获取一级分类和频道组信息
    class ChannelTypesView(ListAPIView):
        serializer_class = channel_serializers.GoodsChannelGroupSerializers
        queryset = GoodsChannelGroup.objects.all()
    
    
    # 3,获取一级分类信息
    class ChannelCategoriesView(ListAPIView):
        serializer_class = channel_serializers.GoodsCategorySerializers
        queryset = GoodsCategory.objects.all()
    

• 3，创建序列化器

  • # 2,定义频道组序列化器
    class GoodsChannelGroupSerializers(serializers.ModelSerializer):
        class Meta:
            model = GoodsChannelGroup
            fields = '__all__'
    
    
    # 3,定义分类序列化器
    class GoodsCategorySerializers(serializers.ModelSerializer):
        class Meta:
            model = GoodsCategory
            fields = '__all__'
    

3 增加，修改，删除数据

• 由于使用的是视图集，所以该功能已实现
