选择2不加载数据

Question

我最近升级到Rails 5.2和ruby 2.5.1，我的选择框停止工作。

我不得不在我的qazxsw poi中更改require文件并添加完整版本甚至查看选择框

admin.js

但现在ajax查询获取数据甚至初始选择都没有显示任何结果。我正在使用//= require select2-full将数据传递给我的js，我已经检查过gon具有正确的值。我的js.coffee如下：

Gon

我的控制器搜索端点：

clientFormatResult = (client) ->
  client.email

clientFormatSelection = (client) ->
  client.email

$ ->
  $select_input = $('#publish_to')
  $select_input.val(' ')
  $select_input.select2({
    width: '420px'
    height: 'auto'
    placeholder: "Search"
    minimumInputLength: 2
    multiple:true
    closeOnSelect: true
    tokenSeparators:[',',' ']
    ajax: {
      url: $select_input.data('search-endpoint')
      data: (term, page) ->
        {
          q: term # search term
          page_limit: 10
        }
      results: (data, page) -> # parse the results into the format expected by Select2.
        console.log("result")
      # since we are using custom formatting functions we do not need to alter remote JSON data
        results: data.manage_clients
      }
    initSelection: (element, callback) ->
      callback(gon.published_to)
    formatResult: clientFormatResult
    formatSelection: clientFormatSelection
  })

搜索端点结果：

def search
    clients = Client.where("email like '%#{params[:q]}%'").map { |c| { :id => c.id, :email => c.email } }
    render :json => clients
  end

private
  def client_params
    params.require(:client).permit(:email, :password, :password_confirmation, :first_name, :last_name, :organisation, :assigned_team)
  end

选择输入所在的视图源代码的提取：

{
"manage_clients": [
{
"id": 46,
"email": "aaaa@example.net"
},
{
"id": 365,
"email": "bbbb@example.org"
}
]
}

我已经尝试了解决控制器的问题<div class="input string required publish_to"> <label class="string required control-label" for="report_clients"> Publish to </label> <input data-search-endpoint="/my-endpoint-search" id="publish_to" name="publish_to" type="hidden" value="" multiple="" tabindex="-1" class="select2-hidden-accessible" aria-hidden="true"><span class="select2 select2-container select2-container--default" dir="ltr" style="width: 420px;"><span class="selection"><span class="select2-selection select2-selection--multiple" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="-1"><ul class="select2-selection__rendered"><li class="select2-search select2-search--inline"><input class="select2-search__field" type="search" tabindex="0" autocomplete="off" autocorrect="off" autocapitalize="off" spellcheck="false" role="textbox" aria-autocomplete="list" placeholder="Search for a client" style="width: 418px;"></li></ul></span></span><span class="dropdown-wrapper" aria-hidden="true"></span></span> <div> <a class="add_button button" href="/some_url">Action</a> </div> </div>，但没有变化。我也尝试将suggested here添加到ajax调用为dataType: 'json'在第一个select2的末尾添加suggested here我尝试手动将.select2('val',[])添加到{ id: '1', text:'example' }我在控制台中没有收到任何错误

但是ajax调用似乎没有起作用。在控制台中没有对搜索端点的调用。
