我的整个 html 文件和视图，我在像 ?page=2&category=3&category=1&category=2&category=3 这样的查询字符串中得到相同的类别查询，当我打印 reqget 时，显示 <QueryDict: {'page': ['1'], 'category': ['3', '1', '2','3']}>
每次点击下一页或上一页时过滤器的问题，网址不清楚，只需在之前的字符串旁边添加相同的内容。它正常工作是显示，但发送到视图的列表如下： ['6', '6', '6', '6', '6', '6', '5', '6'] 我认为它因为用于检查选择。但我不提交它们，只是点击下一页或上一页。
