如何在 Rails 中提交時設置多個默認表單值？

Question

attendance表具有屬性status 、 date 、 recuritment_id和project_site_id 。

project_site與attendance有one_to_many關聯

recuritment與attendance有 one_to_many 關聯。

當屬性status加入出勤#form 視圖時，我正在從recruitment表中獲取屬性。

<% (1..(Time.days_in_month @project_site.attendance_month.strftime("%m").to_i)).each do |date| %> <% (1..(Time.days_in_month @project_site.attendance_month.strftime("%m").to_i)).each do |date| %>這里@project_site.attendance_month包含出勤月份值。 根據月份，我計算天數列以及recuritmnet表中的name 。

這是視圖-

Holydays master 包含相應月份的 Holyday 日期，並在視圖中自動匹配日期並打印“H”，
所有輸入默認選擇為 P。最終的 submit_button 更改 boolean 屬性。 現在在最終提交時，我想將所有默認選擇的P推送到考勤表中。

出勤控制器.rb

<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>

   <tbody>
      <% @recruitment.where(location: @project_site.site_id).each do |recruitment| %>

         <%=f.hidden_field :project_site_id, value: @project_site.id%>

         <% end %>

from.html.erb（出席controller查看）

  def set_submission_status
      @project_site = ProjectSite.find(params[:id])
      @project_site.update(submission_status: true)

  end

project_sites_controller.rb

 def set_submission_status @project_site = ProjectSite.find(params[:id]) @project_site.update(submission_status: true) end

有點不清楚您的問題是什么，但我認為這與您發送回數組操作選項的表單有關。

如果您希望 html 表單返回一個信息數組，那么您需要在 html 中使用name = "attendance[]"語法指出它，注意方括號。
