我在我的應用程序中有一個表單,我正在使用另一個名爲「homework_students」的模型中的單選按鈕來更新名爲「interest」的列中的字段,所以我正在使用(或嘗試!)嵌套形式:RoR:嵌套窗體和補丁
<%= form_for @homework, url: homework_homework_student_path(:homework_id => @homework, home_work_students_id => @homework_student, :controller => 'homeworks', :action => 'update_interest'), method: :patch do |f| %>
<%= f.fields_for :homework_students do |builder| %>
<%= builder.radio_button :interest, '1' %>
</label>
1
<label>
<%= builder.radio_button :interest, '2' %>
</label>
2
<label>
<%= builder.radio_button :interest, '3' %>
3
</label>
<%= f.button :submit %>
<% end %>
<% end %>
在我的模型:
homework.rb:
has_many :homework_students, :class_name => 'HomeworkStudent', dependent: :destroy
accepts_nested_attributes_for :homework_students
homework_students.rb
belongs_to :homework, :class_name => 'Homework', :foreign_key => :homework_id, dependent: :destroy
我想在我的控制器使用的動作(homeworks_controller.rb):
def update_interest
@homework.homework_students.where(id: params[:home_work_students_id]).each do |homework_student| homework_student.update_attributes(:interest)
end
redirect_to @homework, notice: 'Homework was successfully updated.'
end
我想在這裏補丁所以在我的路線:
resources :homeworks do
member do
patch :update_interest
end
resources :homework_students
end
但它似乎並沒有使用「update_interest」操作。我也沒有homework_students控制器。我得到這個錯誤,但也許更多的錯誤以上。
undefined local variable or method `homework_student'
謝謝。欣賞任何指導。可以提供更多信息。
