[英]Rails jQuery sortable unable to save
我正在尝试使用jQuery使表可排序(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。
我正在使用:
gem'acts_as_list'Rails 3.2.17红宝石1.9.3p484
有更好的方法吗?
我在控制器上的排序和显示方法
def sort @episodes = current_user.episodes_for(@show)。每个| 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!
我弄清楚了,进行了以下更改:
观看次数:
<tr id="<%= episode.id %>">
和新的控制器
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
最终将其添加到我的模型中:
acts_as_list
default_scope order('position')
让我知道是否有人遇到类似问题。
