如何在Rails提交中设置多个默认表单值？

attendance该表具有属性status，date，recuritment_id和project_site_id。

project_site与one_to_many有关联attendance

recuritment与拥有“一对多”关联attendance。

recruitment当attribute status＃form视图中加入属性时，我将从表中获取属性。

<% (1..(Time.days_in_month @project_site.attendance_month.strftime("%m").to_i)).each do |date| %>这里@ project_site.attendance_month包含考勤月份值。基于月我计算天数列以及name从recuritmnet表。

这是视图-

holydays主包含对应月份的宗教节日的日期，并鉴于其自动匹配日期和打印“H”，
选择P.所有输入默认有最终submission_button是chnages布尔属性。现在，在最终提交时，我想将所有默认选择的P推送到出勤表中。

  def new
    if @project_site.submission_status == false
      @attendance = Attendance.new

      @date = HolydayCalendar.all

      @recruitment = Recruitment.all.where(current_status: "2")
    else
      redirect_to project_site_attendances_path
    end
  end

from.html.erb（考勤控制器视图）

<table>
   <thead>
      <tr>
         <th class="attendance-emp-name">Emp. Name</th>
         <% (1..(Time.days_in_month @project_site.attendance_month.strftime("%m").to_i)).each do |date| %>
