Python 按类别显示图像

我想按类别显示图像，出现了一个小错误

index（）得到了一个意外的关键字参数“category\u id”

。当我点击分类时，它会显示分配给这个分类的图像。它显示类别，但当我点击它时，我得到了那个错误

我想出来了，我必须更改我的URL.py

    url(r'^(?P<category_id>\d+)/$', views.lists, name='lists'),

url（r'^（？P\d+/$），views.lists，name='lists'），

Chnage您的url:url（r'^（？P\d+/$），views.list，name='list'）和def list（request，category_id）之类的方法：也可以显示您的models.py代码。不知道要写什么请显示您的models.py。在开始时编辑了我的帖子请查看ANS页面上的更改。找不到。photo/1“不存在（r'^photo/（？P\d+）/$，views.list），请尝试此url。然后从DEBUG=True TEMPLATE\u DEBUG=DEBUG更改您的setting.py文件。
