如何使用Rails 3获取隐藏的字段数组值

Question

我的表中有一个隐藏字段。我需要在rails中访问控制器的所有数组值。检查我的下表。

  

paymentresult.html.erb：

<%= form_for :add_payment,:url => {:action => 'add_payment' },remote: true do |f| %>
<table class="table table-bordered">
        <colgroup>
            <col class="col-md-1 col-sm-1">
            <col class="col-md-1 col-sm-1">
            <col class="col-md-3 col-sm-3">
            <col class="col-md-3 col-sm-3">
            <col class="col-md-4 col-sm-4">
        </colgroup>
        <thead>
            <tr>
                <th class="text-center"><input type="checkbox"></th>
                <th class="text-center">Sl. No</th>
                <th class="text-center">Date</th>
                <th class="text-center">Receipt No.</th>
                <th class="text-center">Amount</th>
            </tr>
        </thead>
        <tbody>
            <% @result.each do |r| %>
            <%= hidden_field_tag 'infos[]', r %>
            <tr>
                <th class="text-center"><%= check_box_tag :check_value, 1, :id => "checkbox1-1"  %></th>
                <td class="text-center"><%= r.id %></td>
                <td class="text-center"><%= r.c_date %></td>
                <td class="text-center"><%= r.Receipt_No %></td>
                <td class="text-center"><i class="fa fa-rupee"></i><%= r.v_amount %></td>
            </tr>
            <% end %>
     </tbody>
</table>
 <%= f.submit "Add to payment",:class => "btn btn-success",:id => "switch_car11" %>
<% end %>

  

payment_controller.rb

class PaymentsController < ApplicationController
  def add_payment
    if params[:commit]
        params[:check_value] == '1' ? remember : forget

    else
        if params[:add_payment][:p_catagory]=="Cheque"
            @chk=true
        end
    end
  end
  private
  def remember
    @reslt=params[:infos]
    @add_payment=AddPayment.create(:p_catagory => params[:add_payment][:p_catagory],:paid_amount => "here i want to add the table's v_amount value",:total_claim => 1 )
  end

end

  

add_payment.rb：

class AddPayment < ActiveRecord::Base
  attr_accessible :chk_details, :chk_no, :p_catagory, :paid_amount, :total_claim
end

我需要当用户点击提交按钮然后所有数组值（ie- @结果）应该获取add_payment方法。我尝试使用隐藏字段但无法获取所有数据。这是我的要求是在提交表单之后全部@result的值应该提取到控制器方法中，以便我可以在DB中保存一些值。
