Rails 3：通過索引操作而不是創建遠程（UJS）表單

我在Ruby（1.9.3-p0）上在Rails（3.1.3）上創建了一個應用程序，並且遇到了遠程形式，我用來創建一個對象。表單通過遠程鏈接加載到視圖中，該鏈接將其放入div（在new操作中。表單也標記爲遠程，但是當我提交它時，POST請求會嘗試由index操作處理，而不是create爲什麼會發生這種情況？不應該使用控制器的create動作自動使用基本路由上的POST請求嗎？這裏是相關的代碼和消息：Rails 3：通過索引操作而不是創建遠程（UJS）表單

這是遠程鏈接的視圖加載形式：

<div id="new_higher_education_study"> 
<%= link_to "Nuevo Estudio Superior", new_higher_education_study_path, :remote => true %> 
</div>

這裏是處理所有這些請求控制器：

class HigherEducationStudiesController < ApplicationController 

def new 
    @higher_education_study = HigherEducationStudy.new 

    respond_to do |format| 
     format.js 
    end 
end 

def create 
    @study = HigherEducationStudy.new(params[:higher_education_study]) 
    @higher_education_studies = HigherEducationStudy.get_by_academic_background_id(UserSession.find.user.curriculum_vitae.academic_background_id) 

    respond_to do |format| 
     if @study.save 
      flash[:notice] = "Se ha guardado el Estudio Superior exitosamente." 
     else 
      flash[:notice] = "Error en el guardado del Estudio Superior." 
     end 
     format.js 
    end 
end 
end

然後，各自的觀點是：

new.js.erb：

$('#new_higher_education_study').html("<%= escape_javascript(render :partial => 'higher_education_studies/higher_education_study_form') %>");

create.js.erb：

$('#higher_education_studies_table').html("<%= escape_javascript(render :partial => 'higher_education_studies_table') %>")

在我的routes.rb文件，我只爲該控制器設置了Rails默認資源，如下所示：resources :higher_education_studies, :except => [:index]

的rake routes命令確認路線POST「/ higher_education_studies」鏈接到create行動：

   higher_education_studies POST /higher_education_studies(.:format)     {:action=>"create", :controller=>"higher_education_studies"} 
      new_higher_education_study GET /higher_education_studies/new(.:format)    {:action=>"new", :controller=>"higher_education_studies"} 
      edit_higher_education_study GET /higher_education_studies/:id/edit(.:format)   {:action=>"edit", :controller=>"higher_education_studies"} 
       higher_education_study GET /higher_education_studies/:id(.:format)    {:action=>"show", :controller=>"higher_education_studies"} 
             PUT /higher_education_studies/:id(.:format)    {:action=>"update", :controller=>"higher_education_studies"} 
             DELETE /higher_education_studies/:id(.:format)    {:action=>"destroy", :controller=>"higher_education_studies"}

所以我不明白爲什麼當我提交表單，我得到這個在服務器控制檯：

Started POST "/higher_education_studies" for 127.0.0.1 at 2012-04-10 11:12:53 -0300

Searched in: ...

我試圖把行post '/higher_education_studies', :to => 'higher_education_studies#create'明確地放在路由文件上，但那也沒有奏效。我非常感謝你對這個問題的任何幫助。

如果將來有人有類似的問題，原來的另一部分routes.rb文件搞亂了這個特定的控制器的路由。由於許多人正在爲這個項目工作，也許有人在我的控制器的資源之前製作了一條更一般的路線，以此來抓住我的。我沒有考慮現在是哪個罪魁禍首，我只是將resources :higher_education_studies移到routes.rb文件的頂部，現在它可以工作。
