我正在尝试使用 jQuery 使我的表可排序(拖放),我遇到的问题是保存新的排序表,然后将其发布给其他用户或刷新浏览器时。

我在用着:

宝石'acts_as_list' Rails 3.2.17 ruby​​ 1.9.3p484

有没有更好的方法来做到这一点?

我的控制器上的排序和显示方法

def sort @episodes = current_user.episodes_for(@show).each 做 |episode| episode.position = params['episode'].index(episode.id.to_s) + 1 episode.save end render :nothing =>true end

  def show
    @episodes = current_user.episodes_for(@show)
    @episodes.order('episode.position ASC')
    @episode = @episodes.where(id: params[:id]).first
  end

我的 Javascript

<script>
$(window).load(function() {
    $("#sortthis").sortable({
      axis: 'y',
      placeholder: 'ui-state-highlight',
      cursor: 'move',
      dropOnempty: false,
      scroll: true,
      opacity: 0.4,

      update: function(event, ui){
        var itm_arr = $("#sortthis").sortable('toArray');
        var pobj = {episodes: itm_arr};
        $.post("/episodes/sort", pobj);
      }

    });
});
 </script>

我想在视图中排序的表:

<tbody id='eps'>
<tr>
  <th>Title</th>
  <th>#</th>
  <th>Season</th>
  <th>Download?</th>
  <th>Shared?</th>
  <th>Length</th>
  <th>Status</th>
        <th></th>
</tr>
<% for episode in @episodes %>
  <tr>
    <td id="eps_<%= episode.id %>", width="20%"><%=h episode.title %></td>
    <td id="eps_<%= episode.id %>"><%=h episode.number %></td>
    <td id="eps_<%= episode.id %>"><%=h episode.season %></td>
    <td id="eps_<%= episode.id %>"><%=h episode.is_downloadable %></td>
    <td id="eps_<%= episode.id %>"><%=h episode.shared_with_dev %></td>
    <td id="eps_<%= episode.id %>"><%=h episode.length %></td>
    <td>
      <% if episode.video %>
        <%= link_to 'Replace Video', new_show_episode_video_path(episode.show, episode) %>
      <% else %>
        <%= link_to 'Upload Video', new_show_episode_video_path(episode.show, episode) %>
      <% end %>
    </td>
        <td>
        <%= link_to "View", [episode.show, episode] %> &nbsp;
    <%= link_to "Edit", edit_show_episode_path(episode.show, episode) if permitted_to? :update, episode %> &nbsp;
    <%= link_to "Delete", show_episode_path(episode.show, episode), :confirm => 'Are you sure?', :method => :delete if permitted_to? :delete, episode %>
    </td>
  </tr>
<% end %>

任何帮助将不胜感激!

我想通了,做了以下更改:

意见:

<tr id="<%= episode.id %>">

和新控制器

def sort
  Episode.all.each do |e|
    if position = params[:episodes].index(e.id.to_s)
      e.update_attribute(:position, position + 1) unless e.position == position + 1
    end
  end
  render :nothing => true, :status => 200
end

最后将此添加到我的模型中:

  acts_as_list
  default_scope order('position')

让我知道是否有人有类似的问题。
