Question

我在Rails中使用JQuery Multiselect（http://loudev.com/）。一切都很好，但是没有保存从多选中选择数据的顺序。

我基本上遇到与此问题相同的问题：jquery multiselect selected data order

我需要在Rails中实现类似的解决方案，并且非常感谢任何帮助

这是代码

表格（多选项发生在collection_select中）

:javascript
  $(document).ready(function (){
       $('#load_format_column_sequence').multiSelect({ keepOrder: true });
  });

= form_for [:operate,@biller,@load_format], :remote => true do |form| 
  = form.fieldset :legend => 'General' do
    = form.text :name
    = form.text :load_processor
    = form.text :processor_options
    = form.fields_for(@load_format) do |builder|
      = builder.label "Column Sequence"
      = collection_select(:load_format, :column_sequence, load_format_column_sequence_select, :last, :first,  {}, {:multiple => true})
    = form.checkbox :inactivate_removed_accounts
  = form.fieldset :legend => 'Schedule and Transfer' do
    - @load_format.build_file_transfer_format unless @load_format.file_transfer_format
    = render :partial => 'operate/file_transfer_formats/form', :locals => { :form => form, :file_transfer_format => @load_format.file_transfer_format, :parent => @load_format, :show_schedule => true  }

数据数组

def load_format_column_sequence_select
    {
      'EXTERNAL KEY' => :external_key,
      'EXTERNAL CODE' => :external_code,
      'ACCOUNT TYPE' => :account_type,
      'PAYER NAME' => :payer_name,
      'ALTERNATE PAYER NAME' => :payer_alternate_name,
      'PAYMENT AMOUNT' => :payment_amount,
      'PAYOFF AMOUNT' => :payoff_amount,
      'ACTIVE' => :active,
      'ALTERNATE KEYS' => :alternate_keys,
      'BILL EXTERNAL KEY' => :bill_external_key,
      'BILL EXTERNAL CODE' => :bill_external_code,
      'BILL DUE AMOUNT' => :bill_due_amount,
      'BILL DISCOUNT AMOUNT' => :bill_discount_amount,
      'BILL ALTERNATE KEY' => :bill_alternate_key,
      'DETAIL EXTERNAL KEY' => :detail_external_key,
      'DETAIL AMOUNT' => :detail_amount,
      'DETAIL DESCRIPTION' => :detail_description,
      'GROUP NAME' => :group_name,
      'GROUP EXTERNAL KEY' => :group_external_key,
      'RECENT CHECK ABA' => :recent_check_aba,
      'RECENT CHECK ACCOUNT' => :recent_check_account,
      'RECENT CHECK NUMBER' => :recent_check_num,
      'RECENT CHECK AMOUNT' => :recent_check_amount,
      'PAYER FIRST NAME' => :payer_first_name,
      'PAYER LAST NAME' => :payer_last_name,
      'ACCOUNT DESCRIPTION' => :account_description,
      'HOLD REASON KEYS' => :hold_reason_keys,
      'ACCOUNT ADDRESS LINE 1' => :account_address_line_1,
      'ACCOUNT ADDRESS LINE 2' => :account_address_line_2,
      'ACCOUNT CITY' => :account_city,
      'ACCOUNT STATE' => :account_state,
      'ACCOUNT ZIP CODE' => :account_zip
    }
  end

在模型中我有

serialize(:column_sequence, Array)

...更新

切换到jquery bsmselect，非常相似

解决方案是在load_format_column_sequence_select方法中添加一个参数，传入当前顺序（这是一个字符串数组），在方法内部检查它是否设置，如果没有将其设置为空数组。然后将空哈希设置为新的顺序，迭代当前的字符串顺序数组以重新排序原始列表以匹配列顺序。（得到我的同事的信用）。

def load_format_column_sequence_select(current_order)
    current_order ||= []
    original_order = {
      :external_key => 'EXTERNAL KEY',
      :external_code => 'EXTERNAL CODE',
      :account_type => 'ACCOUNT TYPE',
      .........



    }

    new_order = {}

    current_order.each do |column_key|
      column_key = column_key.to_sym
      if column_name = original_order.delete(column_key)
        new_order[column_key] = column_name
      end
    end
    new_order.merge(original_order)

  end

并以形式....（传入的@ load_format.column_sequence是保存在数据库中的字符串数组）

 = form.fields_for(@load_format) do |builder|
        = builder.label "Column Sequence"
        = collection_select(:load_format, :column_sequence, load_format_column_sequence_select(@load_format.column_sequence), :first, :last,  {}, {:multiple => true})

JQuery Multiselect在Rails中提交时不保存正确的序列
