是否有任何可能的方法来修复Kaminari分页生成的url ?

Question

我在我的应用程序中实现了一个聊天系统，其中只有评论列表将用ajax提交重新加载。

Kaminari分页在那里使用，但它得到奇怪的字符串在它的url像这样的新评论提交后。

example-website.com/users/mike/refresh_part ? _ = 1356906069855,页面= 2

在它的url中有更多奇怪的参数当在另一个控制器中提交注释时。只有当它与垃圾邮件错误匹配时生成的url:

example-website.com/shop/walmart/topic/20/comments ? authenticity_token = 9 nuyeq%2fa0f114vue16rxf7jhspw%2b736e%2bkyzfjiwbkq%3d&评论(身体)= test&提交=创建+ Comment&页面= 2,utf8 =✓

我该如何解决这个问题?

我的代码是

视图/用户/show.html.erb

<%= javascript_tag do %>
    jQuery(document).ready(function () {
        refreshPartial();
        setInterval(refreshPartial, 5000)
    });

    function refreshPartial() {
      $.ajax({
        url: "<%= show_user_path(@user) %>/refresh_part",
        type: "GET",
        dataType: "script",
      });
    }
<% end %>
......
<span id="chat">
<%= render 'users/comment' %>
</span>
<%= render 'users/comment_input' %>

视图/用户/_comment.html.erb

<table>
  <tr>
    <th>ID</th>
    <th>PIC</th>
    <th>Body</th>
    <th>Subject</th>
    <th>Posted by</th>
    <th>Delete</th>
  </tr>
<% @comments.each do |comment| %>
  <tr id="<%= dom_id(comment) %>">
    <td><%= comment.id %></td>
    <td>
            <% if comment.comment_icon? %>
                <ul class="thumbnails">
                <%= image_tag(comment.comment_icon.url(:thumb),:height => 100, :width => 100, :style => 'border:3px double #545565;' ) %>
                </ul>
            <% end %>
    </td>
    <td><%= comment.body %></td>
    <td><%= comment.subject %></td>
    <td><%= comment.user.user_profile.nickname if comment.user.user_profile %></td>
    <td>
    <%= button_to 'destroy', polymorphic_path([@user, comment]), :data => {:confirm => 'Are you sure?'}, :method => :delete, :disable_with => 'deleting...', :remote => true, :class => 'btn btn-danger' if current_user && current_user.id == comment.user_id %>
    </td>
    </tr>
<% end %>
</table>
<%= paginate @comments, :window => 4, :outer_window => 5, :left => 2, :right => 2 %>

/用户/_comment_input.html观点。erb<=这是输入表单!!!!!

<%=form_for(([@user, @comment]), :remote => true) do |f| %>

这是Kaminari的一个已知问题。参见:第132期，第182期。

当前已知的解决方法是手动设置分页帮助器上的参数，例如:

paginate @comments, :params => { :controller => 'comments', :action => 'index', _: nil, _method: nil, authenticity_token: nil, utf8: nil}

您必须调整代码以适应您的情况，并确保在手动设置所有参数时测试所有其他功能是否按预期工作。

既然你特别遇到了URL上的时间戳问题，你应该在第132号问题上发表评论，并在那里发布你的经验细节。您参与github问题的次数越多，您、项目用户和维护者就越有可能找到更好的解决方案。
