Question

在下面发布的代码示例中，我试图允许页面用户过滤掉用户应显示的项目。我可以通过手动修改地址栏中传递的参数来成功过滤结果。但是，当我单击页面上的“过滤器”按钮时，它什么都不做。当按下按钮时，它应该刷新页面并传递新参数。关于为什么会这样的想法？我是否需要在控制器中添加任何内容？

查看：

= form_tag projects_path, :method => :get do
  Include:
- @all_users.each do |user|
  = user
  = check_box_tag "users[#{user}]", 1, @all_users.include?(user), :id => "users_#{user}"
= submit_tag 'Filter', {:id => "users_submit"}

加载主页后的控制台：

单击提交按钮后，控制台中没有任何操作，或者浏览器似乎做了什么。 Rails 3.2.14 Ubuntu 12.04 LTS

使用适当的缩进修复了代码：

= form_tag movies_path, :id => "ratings_form", :method => :get do
  Include: 
  - @all_ratings.each do |rating|
    = rating
    = check_box_tag "ratings[#{rating}]", 1, @ratings.include?(rating), :id => "ratings_#{rating}"
  = submit_tag "Refresh", :id => "ratings_submit"

发布表单时，不会刷新Ruby on Rails页面
