ruby-on-rails - will_paginate 未定义的方法 `total_pages'

我在这里缺少什么？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？
我正在使用 mislav-will_paginate 2.3.11。

最佳答案

尝试改变

@locations.paginate(:page => 1, :per_page => 2)

到

@locations = @locations.paginate(:page => 1, :per_page => 2)

希望这可以帮助
