Question

我收到路由错误：没有路由匹配[POST]“/ students / 1”我无法弄清楚。以下是详细信息。

查看代码：

<% @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

在我的学生管理员中：

def select
  .
  .
end

routes.rb中： HomeSchool :: Application.routes.draw做

  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

佣金路线的输出是：

有什么建议吗？我真的很难理解轨道中的路由应该如何工作，我还没有找到任何类型的论文，但我很确定没有为我的选择路由列出的方法至少是我的问题。

谢谢，

Answer 1

尝试删除match文件中的routes.rb，并将students资源更改为：

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

同时更新您的观看次数以致电select_student_path(student)。

Answer 2

发生这种情况是由于您的route.rb文件。在“ / students / new”中没有post方法的回调

更正此问题。转到routes.rb，并在结尾之前添加Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)。

并检查post 'students/new' to: 'students#new'。您将在那里找到帖子的路由路径。
