问题描述
我在这里错过了什么?我正在使用 haml_scaffold 生成器,并且页面与 will_paginate 一起工作正常.当我开始修补时,我最终遇到了这个total_pages"错误,我不确定我在做什么导致它.任何人都有任何见解?我使用的是 mislav-will_paginate 2.3.11.
What am I missing here? I am using the haml_scaffold generator and the pages work fine with will_paginate. When I start tinkering I end up with this 'total_pages' error and I'm not sure what I am doing that is causing it. Anyone have any insight? I'm using mislav-will_paginate 2.3.11.
