Mongoid 不更新位置字段

Question

我希望能够更新 Attachinary::File 位置字段

我使用 ruby 2.5.0、rails 5.2.2、mongoid、'jquery-ui-rails' 和 自定义附件（https://github.com/ipatovanton/attachinary/tree/position) 图片上传。

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'),
        });
      }
    });
  });
})

routes.rb

resources :projects do
    collection do
      patch :sort
    end
end

project.rb

class Project
  include Mongoid::Document

  has_attachments :images
end

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>

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

当我尝试拖动图像时，我收到了下一条消息。但是位置没有得到更新：

Started PATCH "/projects/sort" for 127.0.0.1 at 2019-01-23 18:19:46 +0300 Processing by ProjectsController#sort as / Parameters: {"image"=>["5c4827691996da1fef832f5d", "5c4827691996da1fef832f6e", "5c4827691996da1fef832f5e", "5c4827691996da1fef832f5f", "5c4827691996da1fef832f60", "5c4827691996da1fef832f61", "5c4827691996da1fef832f62", "5c4827691996da1fef832f63", "5c4827691996da1fef832f64", "5c4827691996da1fef832f65", "5c4827691996da1fef832f66", "5c4827691996da1fef832f67", "5c4827691996da1fef832f68", "5c4827691996da1fef832f69", "5c4827691996da1fef832f6a", "5c4827691996da1fef832f6b", "5c4827691996da1fef832f6c", "5c4827691996da1fef832f6d", "5c4827691996da1fef832f5c"]} MONGODB | localhost:27017 | squarely_development.find | STARTED | {"find"=>"users", "filter"=>{"_id"=>BSON::ObjectId('5c472c2e1996da1d037f57fb')}, "sort"=>{"_id"=>1}, "limit"=>1, "singleBatch"=>true, "lsid"=>{"id"=>}} MONGODB | localhost:27017 | squarely_development.find | SUCCEEDED | 0.001s Completed 200 OK in 6ms

如果我使用 ActiveRecord 并且 gem 'pg' 一切正常

但我需要这个解决方案才能与 Mongodb

一起使用

有人对此有任何想法或想法吗？

谢谢

首先，您似乎正在尝试对项目的图像进行排序。

如果那是真的，那么我建议将这条路线移动到会员而不是 collection。

这意味着您必须添加 sort_project_path(@project)。如果您以与访问图像相同的方式检索图像，这可以让我们的生活更轻松。

class ProjectsController < ApplicationController
  before_action :set_project # You may already have that

  def sort
    params[:image].each_with_index do |id, index|
      @project.images.where(id: id).update_all(position: index + 1)
    end
    head :ok
  end

  def set_project
    @project = Project.find(params[:id])
  end
end

希望对你有用。
