我在 Rails (3.1.3) 上使用 Ruby (1.9.3-p0) 制作应用程序，但我在使用用于创建对象的远程表单时遇到问题。表单通过远程链接加载到视图中，该远程链接将其放入 div 中（在new操作中。表单也标记为远程，但是当我提交它时，POST 请求尝试由index操作而不是create操作处理。为什么会发生这种情况？Rails 不应该自动使用create控制器的动作来处理基本路由上的 POST 请求吗？以下是相关代码和消息：

这是加载表单的视图中的远程链接：

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

这是处理所有这些请求的控制器：

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

那么，各自的观点是：

新的.js.erb：

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

创建.js.erb：

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

在我的 routes.rb 文件中，我只为 Rails 设置了该控制器的默认资源，如下所示：resources :higher_education_studies, :except => [:index]

该rake routes命令确认路由 POST '/higher_education_studies' 链接到create操作：

               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"}

所以我不明白为什么当我提交表单时，我在服务器控制台中得到了这个：

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

我尝试将这条线post '/higher_education_studies', :to => 'higher_education_studies#create'明确地放在路线文件上，但这也没有用。我非常感谢你在这个问题上的任何帮助。

万一以后有人遇到类似的问题，原来 routes.rb 文件的另一部分正在弄乱这个特定控制器的路由。由于很多人都在做这个项目，也许有人做了一个更通用的路线，在我的控制器的资源之前抓住了我的。我暂时没有调查哪个是罪魁祸首，我只是将它移到resources :higher_education_studies了 routes.rb 文件的几乎顶部，现在它可以工作了。
