ruby-on-rails - Mongoid 不更新位置字段

问题描述

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 ) 来上传图片。

应用程序.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'),
        });
      }
    });
  });
})

路线.rb

resources :projects do
    collection do
      patch :sort
    end
end

项目.rb

class Project
  include Mongoid::Document

  has_attachments :images
end

显示.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>

项目控制器.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，我会收到下一条消息。但是职位没有更新：

2019-01-23 18:19:46 +0300 为 127.0.0.1 启动 PATCH "/projects/sort" 由 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 | 本地主机：27017 | squarely_development.find | 开始 | {"

如果我使用 ActiveRecord 和 gem 'pg' 一切正常

但我需要这个解决方案来使用 Mongodb

有人对此有任何想法或想法吗？

谢谢

解决方案

首先，您似乎正在尝试对项目的图像进行排序。

如果这是真的，那么我建议将这条路线移动到成员而不是集合上。

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

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

我希望这对你有用。
