如何在 rails 提交时设置多个默认表单值？

Question

attendance table 有属性 status, date,recuritment_id 和 project_site_id 。

project_site 与 attendance

有 one_to_many 关联

recuritment与attendance有one_to_many关联。

当属性 status 加入考勤#form 视图时，我正在从 recruitment table 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 包含出勤月份值。根据月份，我从 recuritmnet table 计算天数列以及 name。

这里是视图-

holydays master 包含相应的月份 holyday 的日期并在视图中自动匹配日期并打印“H”，
所有输入默认选择为 P。最终 submission_button 更改布尔属性。现在在最终提交时，我想将所有默认选择的 P 推入出席 table.

attendance_controller.rb

  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| %>
         <th class="text-center"><%= date %></th>
         <% end %>
      </tr>
   </thead>
   <tbody>
      <% @recruitment.where(location: @project_site.site_id).each do |recruitment| %>

project_sites_controller.rb

  def set_submission_status

      @project_site.update(submission_status: true)

  end

有点不清楚你的问题是什么，但我认为它与你的表单发回数组操作选项有关。

如果你想让你的 html 表单成为 return 一个信息数组，那么你需要在你的 html 中使用 name = "attendance[]" 语法指明它，注意方括号。
