ruby-on-rails - 如何在 Rails 中提交时设置多个默认表单值？

Question

attendance采用的表具有属性 status、date、recuritment_id 和 project_site_id。

project_site与 attendance 有one_to_many 关联

recuritment与 attendance 有一对多关联.

我正在从 recruitment 获取属性表格 when 属性 status加入考勤#form View 。

<% (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，我计算天数列以及 name来自 recuritmnet table 。

这里是 View -

holydays master 包含相应月份的 holyday 的日期并在 View 中自动匹配日期并打印“H”，
所有输入默认选择为 P。最后的 submission_button 更改 bool 属性。现在在最终提交时，我想将所有默认选择的 P 插入出勤表。

考勤 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 Controller View )

<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>

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。

如果您希望您的 html 表单返回一组信息，那么您需要使用 name = "attendance[]" 语法在您的 html 中指明它，注意方括号。
