我的应用程序中有一个表单,我希望更新一个名为" interest"的列中的字段。使用另一个名为" homework_students"所以我正在使用(或尝试!)嵌套表格:
<%= 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 %>
在我的模特中:
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
我想在我的控制器中使用的操作(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
我正在尝试Patch,所以在我的路线中:
resources :homeworks do
member do
patch :update_interest
end
resources :homework_students
end
但它似乎没有使用&#34; update_interest&#34;行动。我也没有homework_students控制器。我得到了这个错误,但上面也可能更加错误。
undefined local variable or method `homework_student'
感谢。感谢任何指导。可以提供更多信息。

您的模型文件名似乎不正确。(homework_students.rb) 它应该是单数的(homework_student.rb)。您的模型类名称也将是单数。
