我有一个问题要问的是,如何根据动态选择标准展示和更新铁路模型的许多要素。
我正在创建一个应用程序, 使您能够通过一系列“ 活动” 仓库的“ 历史” 作为活动记录关系 。 最初, 我希望用户选择一个日期范围, 事件将在其中被限制 。 然后该页面应该从第一个事件开始, 在日期范围内加载一个表格( 或仅仅是表格的一部分 ) 。
然后,用户应该能够使用左/右按钮跨过事件表,一系列业务数字将动态更新,以响应我们在表格中遇到的事件,即在跨过头五个事件之后,总收入数字将是这五个事件的收入总和。
最理想的是,我也想在谷歌可视化上 展示这些信息...
是否有人能指引我正确方向? 我理解控制器的侧面处理方法,以便从数据库表格中获得正确的选择,但我不确定我应该如何处理与Ajax的请求,我应该多经常地要求客户提出新的请求。
任何忠告都感激不尽 谢谢
AJAX 请求的处理方式与普通 HTTP 请求的处理方式相同, 您只需要确保您设置了正确的路线。 主要不同之处在于您通常会制作一个 < code>. js.erb 文件, 而不是一个 < code>.html.erb 文件( 假设您再次使用 ERB ) 。
网上有许多关于这个问题的材料,最好的起点之一是铁路指南——http://guides.rubyonrails.org/layouts_and_rendering.html 。
PS:请注意,你的问题非常广泛,所以你不可能得到很好的答案。
