Question

我正在尝试建立一个页面，用户在调用模型Entreprise时可以将：city和：sector过滤器组合在一起。当我只有：city时，设置运行良好，但是当添加：sector时，页面不再更新。请问我做错了什么？有谁知道如何组合这些过滤器？

我的索引页面

  <div class="col-md-12">
    <%= form_tag events_path, method: 'get', id: "events_search" do %>
      <% @cities = Event.all.distinct.pluck(:city) - ["", nil] %>
      Filter by cities:
      <% @cities.each do |city| %>
        <div class="btn btn-default">
          <%= check_box_tag "by_cities[]", city %> <%= city %>
        </div>
      <% end %>
      <% @sectors = Event.all.distinct.pluck(:sector) - ["", nil] %>
      Filter by sector:
      <% @sectors.each do |sector| %>
        <div class="btn btn-default">
          <%= check_box_tag "by_sectors[]", sector %> <%= sector %>
        </div>
      <% end %>
    <% end %>

    <br>
  </div>


</div>

<div id="events"><%= render 'principal' %>  </div>

</div>
<script type="text/javascript">
    $(function () {
        $('input[type=checkbox]').change(function () {
            $.get($('#events_search').attr('action'),
                $('#events_search').serialize(), null, 'script');
            return false;
        });
        $('#events_search').submit(function () {
            $.get(this.action, $(this).serialize(), null, 'script');
            return false;
        });
    });

</script>

我的控制器看起来像：

class EventsController < ApplicationController
  before_action :authenticate_user!
  has_scope :by_cities, type: :array
  has_scope :by_sectors, type: :array

  def index
    @events = apply_scopes(Event).all.order("created_at DESC")

  end

我的模型：

scope：by_cities，->城市{where（：city => city）} 范围：by_sectors，->部门{where（：sector =>部门）}

index.js.erb

$('#events').html('<%= escape_javascript(render('principal')) %>')

在Rails中将过滤器与“ has_scope”和Ajax gem结合在一起的问题
