Question

我希望能够按位置对图像进行排序

我使用ruby 2.5.0，rails 5.2.2，mongoid，'jquery-ui-rails'和Attachinary（https://github.com/ipatovanton/attachinary/tree/position）上传图片。

projects_controller.rb

class ProjectsController < ApplicationController
  def sort
    params[:image].each_with_index do |id, index|
      Attachinary::File.where(id: id).update_all(position: index + 1)
    end
    head :ok
  end
end

project.rb

class Project
  include Mongoid::Document

  has_attachments :images
end

routes.rb

resources :projects do
    collection do
      patch :sort
    end
end

application.js

jQuery(function() {
  $(document).on('turbolinks:load', function(){
    $('.attachinary-input').attachinary()

    $("#images").sortable({
      update: function(e, ui) {
        Rails.ajax({
          url: $(this).data("url"),
          type: "PATCH",
          data: $(this).sortable('serialize'),
        });
      }
    });
  });
})

show.html.erb

<div id="images" class="grid" data-url="<%= sort_projects_path %>">
  <% @project.images.order(position: :desc).each do |image| %>
    <div id="image_<%= image.id %>" class="box">
      <div class="box-image">
        <%= cl_image_tag(image.path, width: '250', height: '250', crop: 'thumb') %>
      </div>
    </div>
  <% end %>
</div>

当我尝试拖动图像时，会收到下一条消息。但是什么也没发生：

在2019-01-23 18:19:46为127.0.0.1启动PATCH“ / projects / sort” +0300由ProjectsController＃sort作为 / 处理参数：{“ image” => [“ 5c4827691996da1fef832f5d”，“ 5c4827691996da1fef832f6e”， “ 5c4827691996da1fef832f5e”，“ 5c4827691996da1fef832f5f”， “ 5c4827691996da1fef832f60”，“ 5c4827691996da1fef832f61”， “ 5c4827691996da1fef832f62”，“ 5c4827691996da1fef832f63”， “ 5c4827691996da1fef832f64”，“ 5c4827691996da1fef832f65”， “ 5c4827691996da1fef832f66”，“ 5c4827691996da1fef832f67”， “ 5c4827691996da1fef832f68”，“ 5c4827691996da1fef832f69”， “ 5c4827691996da1fef832f6a”，“ 5c4827691996da1fef832f6b”， “ 5c4827691996da1fef832f6c”，“ 5c4827691996da1fef832f6d”， “ 5c4827691996da1fef832f5c”]} MONGODB |本地主机：27017 | squarely_development.find |已开始| {“查找” =>“用户”， “ filter” => {“ _ id” => BSON :: ObjectId（'5c472c2e1996da1d037f57fb'）}， “ sort” => {“ _ id” => 1}，“ limit” => 1，“ singleBatch” => true， MONGODB |“ lsid” => {“ id” =>}}本地主机：27017 | squarely_development.find |成功| 0.001s在6ms内完成200 OK

更新：如果我使用ActiveRecord和gem'pg'一切正常

但是我需要这种解决方案才能与Mongodb一起使用

有人对此有任何想法或想法吗？

谢谢
