帖子無法更新

我試圖更新帖子，它告訴我「目標語言已成功更新」，但實際上只要我點擊更新按鈕，帖子就會回到原來的位置。我在日誌中找不到任何錯誤消息，任何人都可以幫助我？帖子無法更新

結果當我運行耙路線

project_target_langs GET /projects/:project_id/target_langs(.:format)   target_langs#index 
         POST /projects/:project_id/target_langs(.:format)   target_langs#create 
new_project_target_lang GET /projects/:project_id/target_langs/new(.:format)  target_langs#new 
edit_project_target_lang GET /projects/:project_id/target_langs/:id/edit(.:format) target_langs#edit 
    project_target_lang GET /projects/:project_id/target_langs/:id(.:format)  target_langs#show 
         PUT /projects/:project_id/target_langs/:id(.:format)  target_langs#update 
         DELETE /projects/:project_id/target_langs/:id(.:format)  target_langs#destroy 
         POST /projects/:project_id/target_langs/:id(.:format)  target_langs#update

我的控制器代碼

def update 

    @project = Project.find(params[:project_id]) 
    @targetLang = @project.targetLangs.find(params[:id]) 


    respond_to do |format| 
     if @targetLang.update_attributes(params[:targetLang]) 
     format.html { redirect_to project_path(@project), notice: 'Target language was successfully updated.' } 
     format.json { head :no_content } 
     else 
     format.html { render action: "edit" } 
     format.json { render json: @project.errors, status: :unprocessable_entity } 
     end 
    end 
    end

Show.erb

<% @project.targetLangs.each do |targetLang| %> 

    <%= form_for([targetLang.project, targetLang]) do |f| %> 

      <%= f.text_field :language, :class => 'textbox1' %> 
      <%= f.text_field :status, :class => 'textbox1' %> 
      <%= f.text_area :notes, :size => "30x2", :class => 'textbox1' %> 
      <%= link_to 'Remove', [targetLang.project, targetLang], 
        :data => {:confirm => 'Confirm deletion!'}, 
        :method => :delete %> 
      <%= link_to 'Update', [targetLang.project, targetLang], 
        :method => :update %>

的routes.rb

Dashboard::Application.routes.draw do 
    resources :projects do 
    resources :target_langs 
    match '/target_langs/:id' => 'target_langs#update', :via => :post 

end

請添加#update動作的日誌部分，以便我們可以檢查它是否實際更新數據庫 – 2012-07-31 14:41:26

@AnonyAlberto oops，我確實有另一部分代碼，我上傳了它。 – 2012-07-31 15:10:35

我覺得這裏有一個簡單的問題。

你有兩個環節，一是：刪除（我猜的作品），另一個用於：更新（這不工作）

簡單地說，在HTML的<a>標籤（這是什麼link_to收益）會不提交表格。

當你在你的例子中點擊「更新」時，你發送的唯一參數就是id。

相反，你應該說submit_tag("Update")

這將提交表單，所有應該很好。

你的意思是將<％= link_to'更新'，[targetLang.project，targetLang]，：method =>：update％>改成<％= submit_tag（「Update」）％>？我試過了，它仍然不起作用。 – 2012-07-31 15:01:48

以及'link_to'永遠不會工作。在這種情況下，還必須有另一個問題。 – 2012-07-31 15:05:23

我更新了我的日誌，並且可以檢查它是否在數據庫中更新？ – 2012-07-31 15:12:35
