ルーティング エラーが表示されます: [POST] "/students/1" に一致するルートがありません。詳細はこちら。

ビューコード:

<% @students.each do |student| %>
.
.
    <td><%= link_to 'Show', student %></td>
    <td><%= link_to 'Edit', edit_student_path(student) %></td>
    <td><%= link_to 'Select Subjects', select_path(student) %></td>  # error occurs here

私の学生のコントローラーでは： 

def select
  .
  .
end

routes.rb: HomeSchool::Application.routes.draw do

  resources :notes

  resources :assignments

  resources :subjects do
    resources :assignments, :only => [:create, :index, :new]
  end

  resources :students

  resources :resources

  match "students/:id/select" => "students#select", :as => :select

  root :to => 'students#index'

end

rake ルートからの出力は次のとおりです。

助言がありますか？レールでのルーティングがどのように機能するかを正確に把握するのに非常に苦労しており、それに関する論文をまだ見つけていませんが、選択したルートにメソッドがリストされていないことは少なくとも私の問題。

ありがとう、

ファイル内の を削除して、リソースを次のように変更してみてmatchください。routes.rbstudents

resources :students do
  member do
    get 'select'
  end
end

また、ビューを call に更新しますselect_student_path(student)。
