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] %>
<%= link_to "Edit", edit_show_episode_path(episode.show, episode) if permitted_to? :update, episode %>
<%= 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!
