的Rails的form_for編輯時不保存更改

我新的軌道和有麻煩我的編輯表單更新屬性。的Rails的form_for編輯時不保存更改

這裏是我的項目，並注意的routes.rb：

這是我在查看/筆記/ edit.html.erb的form_for：

 <%= form_for [@project, @note] do |f| %> 

     <div class="form-group"> 
      <%= f.label :title %> 
      <%= f.text_field :title, class: "form-control" %> 
     </div> 

     <div class="form-group"> 
      <%= f.label :body %> 
      <%= f.text_area :body, rows: 10, class: "form-control" %> 
     </div> 

     <div class="action"> 
      <%= f.submit "Save Note", class: "btn btn-success" %> 
     </div> 
     <% end %>

最後，這是我的notes_controller.rb：

class NotesController < ApplicationController 

    before_action :find_note, only: [:show, :edit, :update, :destroy] 

    def index 
     @notes = Note.all 
    end 

    def new 
     @project = Project.find(params[:project_id]) 
     @note = @project.notes.new 
    end 

    def create 
     @project = Project.find(params[:project_id]) 
     @note = @project.notes.build(note_params) 
     @note.project = @project 
     @note.save ? flash[:notice] = "Note created." : flash[:error] = "Note could not be created, please try again." 
     redirect_to [current_user, @project] 
    end 

    def show 
    end 

    def edit 
    end 

    def update 
     if @note.update_attributes(note_params) 
     @note.save 
     flash[:notice] = "Note updated." 
     redirect_to authenticated_root_path 
     else 
     flash[:error] = "Could not update note." 
     render :edit 
     end 
    end 

    def destroy 
     @note.delete ? flash[:notice] = "Note deleted." : flash[:error] = "Note could not be deleted." 
     redirect_to user_project_path 
    end 

    private 

    def note_params 
     params.require(:note).permit(:title, :body) 
    end 

    def find_note 
     @project = Project.find(params[:project_id]) 
     @note = @project.notes.find(params[:id]) 
    end 
    end

這是我的終端輸出：

在此先感謝您的任何建議。

如果您正在使用@project.notes.build(note_params)。不需要這個@note.project = @project中，如果你使用的是@note.update_attributes(note_params) 這不是必需的@note.save 和更好的請嘗試使用調試它創建行動

，並在更新

@note.update_attributes!(note_params)

它會給你爲什麼它無法保存。

<%= form_for [@project, @note], :url => project_note_path(@project,@note), :method => :put do |f| %>

雖然這確實提供了改進，它不提供該問題的原因。正在發出GET請求。 –

@ d端GET請求已經發出你是對的，但對編輯操作不進行更新。 –

是的，完全相同的頁面這種形式的。 –
