javascript – select2不保存编辑输入

由于某种原因,当用户进入编辑条目时,不会显示通过.select2输入的数据.数据已保存.

irb(main):001:0> Routine.find(1)
=> #<Routine id: 1,missed_days: 0,date_started: "2015-10-24 04:00:00",trigger: "brew tea",action: "stretch",user_id: 1,created_at: "2015-11-24 21:55:25",updated_at: "2015-12-14 21:00:09",committed: ["sun","mon","tue","wed","thu","fri","sat",""],days_challenged: 30>

    respond_modal_with @routine
  end

解决方法

这是我在我的select2字段上所做的

<%= f.input :field_name,as: :select,collection: f.object.field_name,include_blank: false,selected: f.object.field_name,input_html: { class: "json_data" },%>

json_data是如何使文本字段进入选择2

咖啡

$('.json_datas').before ()->
    "<input name='#{@.name}' type='hidden' />"
  $('.json_data').select2
    allowClear: true,placeholder: "Select a value",ajax:
      url: '/api/call_to_data'
      dataType: 'json'
      delay: 250
      data: (params) ->
        {
          q: params.term
          page: params.page
        }
      processResults: (data,page) ->
        # parse the results into the format expected by Select2.
        # since we are using custom formatting functions we do not need to
        # alter the remote JSON data
        { results: data.items }
      cache: true
