Ruby on rails Can'；我不知道我的路由错误是从哪里来的

所以我第一次尝试实现多态关联，但遇到了一点麻烦

我试图允许用户在联系人或组织上留下便条。但是在我提交了一张便条之后，我遇到了一个路由错误

以下是我的路线：

这是我的routes.rb文件：

Rails.application.routes.draw do
  get 'welcome/index'

  resources :organizations do
    resources :contacts do 
      resources :notes, module: :contacts
    end
    resources :notes, module: :organizations
  end

  root 'welcome#index'
end

class NotesController < ApplicationController

  def create
    @note = @noteable.notes.new note_params

    redirect_to @noteable, notice: "Your note was successful!!!"
  end

  private

  def note_params
    params.require(:note).permit(:note_title, :note_body)
  end
end

class Contacts::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Contact.find(params[:contact_id])
  end
end

class Organizations::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Organization.find(params[:organization_id])
  end
end

<h1>New Note</h1>
<%= form_for [noteable, Note.new] do |form| %>

  <p>
    <%= form.label :note_title %><br>
    <%= form.text_field :note_title %>
  </p>
  <p>
    <%= form.label :note_body %><br>
    <%= form.text_area :note_body %>
  </p>

  <p>
    <%= form.submit %>
  </p>
<% end %>

这是我的notes\u controller.rb文件：

Rails.application.routes.draw do
  get 'welcome/index'

  resources :organizations do
    resources :contacts do 
      resources :notes, module: :contacts
    end
    resources :notes, module: :organizations
  end

  root 'welcome#index'
end

class NotesController < ApplicationController

  def create
    @note = @noteable.notes.new note_params

    redirect_to @noteable, notice: "Your note was successful!!!"
  end

  private

  def note_params
    params.require(:note).permit(:note_title, :note_body)
  end
end

class Contacts::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Contact.find(params[:contact_id])
  end
end

class Organizations::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Organization.find(params[:organization_id])
  end
end

<h1>New Note</h1>
<%= form_for [noteable, Note.new] do |form| %>

  <p>
    <%= form.label :note_title %><br>
    <%= form.text_field :note_title %>
  </p>
  <p>
    <%= form.label :note_body %><br>
    <%= form.text_area :note_body %>
  </p>

  <p>
    <%= form.submit %>
  </p>
<% end %>

class NotesController

这是我的联系人/notes\u controller.rb文件：

Rails.application.routes.draw do
  get 'welcome/index'

  resources :organizations do
    resources :contacts do 
      resources :notes, module: :contacts
    end
    resources :notes, module: :organizations
  end

  root 'welcome#index'
end

class NotesController < ApplicationController

  def create
    @note = @noteable.notes.new note_params

    redirect_to @noteable, notice: "Your note was successful!!!"
  end

  private

  def note_params
    params.require(:note).permit(:note_title, :note_body)
  end
end

class Contacts::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Contact.find(params[:contact_id])
  end
end

class Organizations::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Organization.find(params[:organization_id])
  end
end

<h1>New Note</h1>
<%= form_for [noteable, Note.new] do |form| %>

  <p>
    <%= form.label :note_title %><br>
    <%= form.text_field :note_title %>
  </p>
  <p>
    <%= form.label :note_body %><br>
    <%= form.text_area :note_body %>
  </p>

  <p>
    <%= form.submit %>
  </p>
<% end %>

class Contacts:：NotesController

这是我的组织/notes\u controller.rb文件：

Rails.application.routes.draw do
  get 'welcome/index'

  resources :organizations do
    resources :contacts do 
      resources :notes, module: :contacts
    end
    resources :notes, module: :organizations
  end

  root 'welcome#index'
end

class NotesController < ApplicationController

  def create
    @note = @noteable.notes.new note_params

    redirect_to @noteable, notice: "Your note was successful!!!"
  end

  private

  def note_params
    params.require(:note).permit(:note_title, :note_body)
  end
end

class Contacts::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Contact.find(params[:contact_id])
  end
end

class Organizations::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Organization.find(params[:organization_id])
  end
end

<h1>New Note</h1>
<%= form_for [noteable, Note.new] do |form| %>

  <p>
    <%= form.label :note_title %><br>
    <%= form.text_field :note_title %>
  </p>
  <p>
    <%= form.label :note_body %><br>
    <%= form.text_area :note_body %>
  </p>

  <p>
    <%= form.submit %>
  </p>
<% end %>

类组织：：NotesController

这是我的视图/notes/_form.html.rb文件：

Rails.application.routes.draw do
  get 'welcome/index'

  resources :organizations do
    resources :contacts do 
      resources :notes, module: :contacts
    end
    resources :notes, module: :organizations
  end

  root 'welcome#index'
end

class NotesController < ApplicationController

  def create
    @note = @noteable.notes.new note_params

    redirect_to @noteable, notice: "Your note was successful!!!"
  end

  private

  def note_params
    params.require(:note).permit(:note_title, :note_body)
  end
end

class Contacts::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Contact.find(params[:contact_id])
  end
end

class Organizations::NotesController < ApplicationController

  private

  def set_noteable
    @noteable = Organization.find(params[:organization_id])
  end
end

<h1>New Note</h1>
<%= form_for [noteable, Note.new] do |form| %>

  <p>
    <%= form.label :note_title %><br>
    <%= form.text_field :note_title %>
  </p>
  <p>
    <%= form.label :note_body %><br>
    <%= form.text_area :note_body %>
  </p>

  <p>
    <%= form.submit %>
  </p>
<% end %>

新注释

如果你还需要什么，我会提供的！提前谢谢你

尝试更改此选项：

resources :organizations do
  resources :contacts do 
    resources :notes, module: :contacts
  end
  resources :notes, module: :organizations
end

对这些行：

resources :organizations do
  resources :contacts do 
    resources :notes
  end
  resources :notes
end

您不需要模块，因为它们已经被父资源限定了范围

同时将

联系人/notes\u controller.rb

移动到

组织/contacts/notes\u controller.rb

。确保也将视图移动到相应的文件夹中

希望有帮助：）

我这样做了，但还是有错误。现在它是NotesController#create error中的一个NoMethodError，错误消息是“nil:NilClass的未定义方法'notes'”。您需要将set_notable方法从其他控制器移动到此控制器中，并使用before#u操作筛选器。
