Question

通过引用，我在ParticipantAttendance，TeamAttendance表中存储具有多对多关系的值。该表包含Participant表和Event表的引用。

我使用ParticipantAttendance的Index页面和TeamAttendance来存储值。

路线档案：

Rails.application.routes.draw do
 resources :team_results do
   collection do
    put :result
   end
 end
resources :participant_results do
  collection do
   put :result
  end
end
resources :team_attendances do
  collection do
   put :attendance
  end
end

resources :participant_attendances do
  collection do
      put :attendance
  end
end
resources :groupinfos
resources :events
resources :participants
get 'results/index'
get 'attendance/index'
root "participants#index"
end

在设置participant_result，team_results和参与者，事件之间的关系之前。出勤模块自动存储值，但现在它没有按照预期存储值。

event.rb：

class Event < ActiveRecord::Base

has_many :selections
has_many :participants, through: :selections

has_many :groupevents
has_many :groupinfos, through: :groupevents

has_many :participant_attendances
has_many :participants, through: :participant_attendances

has_many :participant_results
has_many :participants, through: :participant_results

has_many :team_attendances
has_many :groupinfos, through: :team_attendances

has_many :team_results
has_many :groupinfos, through: :team_results

validates :name, presence: true
end

participant.rb：

class Participant < ActiveRecord::Base

has_many :selections
has_many :events, through: :selections

has_many :groupdetails
has_many :groupinfos, through: :groupdetails

has_many :participant_attendances
has_many :events, through: :participant_attendances

has_many :participant_results
has_many :events, through: :participant_results


validates :name, presence: true
validates :email,:email => true
validates :phone,presence: true,
                 numericality: true,
                 length: { :minimum => 10, :maximum => 10 }
validates :college, presence: true

def full_info
    "#{name}, Participant ID: #{id} "
end
end

participant_attendance.rb：

class ParticipantAttendance < ActiveRecord::Base
 belongs_to :participant
 belongs_to :event
end

participant_attendances / index.html.erb：

<p id="notice"><%= notice %></p>
<h1>Listing Participant Attendances</h1>
<%= form_tag attendance_participant_attendances_path, method: :put do %>
Round 1
<%= radio_button_tag "round", 1 %>|
Round 2
<%= radio_button_tag "round", 2 %>| 
Round 3
<%= radio_button_tag "round", 3 %>|
Round 4
<%= radio_button_tag "round", 4 %>|
Round 5
<%= radio_button_tag "round", 5 %><br><br>
Present : 
<%= radio_button_tag "mark_present", "present" %>|
Absent  :
<%= radio_button_tag "mark_present", "absent" %><br><br>
<%= submit_tag "Mark Attendance" %>  
<table>
<thead>
<tr>
  <th></th>
  <th>Participant</th>
  <th>Events</th>
  <th>Round</th>
  <th>Status</th> 
  <th colspan="5"></th>
</tr>
</thead>
<tbody>
<% @participant_attendances.each do |participant_attendance| %>
  <tr>
    <td><%= check_box_tag "p_ids[]", participant_attendance.id %></td>      
    <td><%= participant_attendance.participant.name %></td>
    <td><%= participant_attendance.event.name %></td>
    <td><%= participant_attendance.round %></td>
    <td><%= participant_attendance.status %></td>  
    <td><%= link_to 'Show', participant_attendance %></td>
    <td><%= link_to 'Edit', edit_participant_attendance_path(participant_attendance) %></td>
    <td><%= link_to 'Destroy', participant_attendance, method: :delete, data: { confirm: 'Are you sure?' } %></td>
  </tr>
<% end %>
</tbody>
</table>
<% end %>

ParticipantAttendancesController文件方法：

def attendance
params[:p_ids]
if params[:mark_present]=="present"
  ParticipantAttendance.where(id: params[:p_ids]).update_all(status: 'Present', round: params[:round])
else
  ParticipantAttendance.where(id: params[:p_ids]).update_all(status: 'Absent', round: params[:round])
end  

redirect_to participant_attendances_url
end

有什么问题？

Answer 1

只有在第一次提交表单重定向后刷新页面时，该表单才起作用。我发现提交按钮没有将值提交给控制器。

，但是刷新页面后，它运行正常。

我禁用了turbolinks的此表单提交功能，并且有效。

模型不存储值
