发布表单时，Ruby on Rails页面不会刷新 [英] Ruby on Rails page does not refresh when form is posted
问题描述
在下面发布的代码示例中，我试图允许页面的用户过滤出用户应显示哪些项目.我可以通过手动修改在地址栏中传递的参数来成功过滤结果.但是，当我单击页面上的筛选器"按钮时，它什么也没做.当按下按钮时，它将刷新页面并传递新的参数.有什么想法为什么会这样?我需要在控制器中添加任何内容吗?
In the code sample posted below, I am trying to allow the user of the page to filter out which projects should be displayed by user. I am able to successfully filter the results by manually modifying the parameters passed in the address bar. But when I click the Filter button on the page it does nothing at all. It should refresh the page with the new parameters being passed when the button is pressed. Any ideas as to why this happens? Do I need to add anything in my controller?

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"}

单击提交"按钮后，控制台中没有任何反应，或者浏览器似乎无任何作用. 导轨3.2.14 Ubuntu 12.04 LTS
After clicking the submit button, nothing happens in the console, or does the browser seem to do anything. Rails 3.2.14 Ubuntu 12.04 LTS
推荐答案
代码已使用适当的缩进进行了固定:
Code was fixed with proper indentation:
= 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"
