我知道这个问题在网上贴满了，但是看了所有的答案后，我仍然无法弄清楚我的问题是什么。

这是我的路线：

resources :applications do 
  resources :applicants do
    collection {put '/archived'}
    collection {put '/not_archived'}
  end
end

然后我在这个路径上有一个表：/applications/1/applicants它调用我的索引方法。

在这个列出所有申请人的表中，我为每一行设置了一个复选框，当他们选中该框时，我想使用 ajax 在数据库中为该行设置“归档”标志。

这是我的ajax调用：

$('.archive').on('click', function() {
    if ($(this).is(':checked')) {
        $.ajax({
            type: "PUT",
            url: '/applications/<%= @application.id %>/applicants/archived',
            data: {id: $(this).attr('id'), archived: true}
        });
    } else {
        $.ajax({
            type: "PUT",
            url: '/applications/<%= @application.id %>/applicants/not_archived',
            data: {id: $(this).attr('id'), archived: false}
        });
    }
});

但是每次我检查一个复选框时，我都会收到此错误：

Started PUT "/applications/1/applicants/archived" for 127.0.0.1 at 2013-04-03 00:07:20 -0500

我的申请人控制器有这些方法：

# PUT /applicants/archived/1
  def archived
    p 'here?'
    @applicant = Applicant.find(params[:id])
    @applicant.archived = params[:archived]
    #@application = current_company.applications.find(params[:application_id])

    respond_to do |format|
      if @applicant.save
        format.js 
        #format.html { redirect_to @task, notice: 'Task was successfully updated.' }
        #format.json { head :no_content }
      else
        format.html { render action: "index" }
        format.json { render json: @applicant.errors, status: :unprocessable_entity }
      end
    end
  end

  # PUT /applicants/not_archived/1
  def not_archived
    @applicant = Applicant.find(params[:id])
    @applicant.archived = params[:archived]
    #@application = current_company.applications.find(params[:application_id])

    respond_to do |format|
      if @applicant.save
        format.js
        #format.html { redirect_to @task, notice: 'Task was successfully updated.' }
        #format.json { head :no_content }
      else
        format.html { render action: "index" }
        format.json { render json: @applicant.errors, status: :unprocessable_entity }
      end
    end
  end

这是我对这些路由的 rake 路由输出：

        archived_application_applicants PUT    /applications/:application_id/applicants/archived(.:format)                            applications/:application_id/applicants#archived
    not_archived_application_applicants PUT    /applications/:application_id/applicants/not_archived(.:format)                        applications/:application_id/applicants#not_archived
                 application_applicants GET    /applications/:application_id/applicants(.:format)                                     applicants#index
                                        POST   /applications/:application_id/applicants(.:format)                                     applicants#create
              new_application_applicant GET    /applications/:application_id/applicants/new(.:format)                                 applicants#new
             edit_application_applicant GET    /applications/:application_id/applicants/:id/edit(.:format)                            applicants#edit
                  application_applicant GET    /applications/:application_id/applicants/:id(.:format)                                 applicants#show
                                        PUT    /applications/:application_id/applicants/:id(.:format)                                 applicants#update
                                        DELETE /applications/:application_id/applicants/:id(.:format)                                 applicants#destroy

是什么导致我的错误？我完全被难住了。

我希望这段代码对你有用：

$('.archive').on('click', function() {                                                      

if ($(this).is(':checked')){
    $.ajax({
        type: "PUT",
        url: '<%= archived_application_applicants_path(@application.id) %>',
        data: {id: $(this).attr('id'), archived: true}
    });
}else {
    $.ajax({
        type: "PUT",
        url: '<%= not_archived_application_applicants_path(@application.id) %>',
        data: {id: $(this).attr('id'), archived: false}
    });
}

});

我制作了一个复制您的上下文的演示应用程序，它对我来说效果很好。你可以在这里查看：https ://github.com/Chipairon/so_applicants_route

我已经清理了围绕这个问题的噪音，希望它可以作为一个起点。

我没有足够的声誉来评论你的问题，所以我会把它放在这里:)

我认为问题必须出在您身上，app/views/applicants/archived.js.erb因为您说问题是在您选中复选框时发生的。你能发布那个文件的内容吗？

在旁注中，我希望您考虑将“存档”操作作为成员操作。您实际上是对单个申请人执行操作，而不是对所有申请人执行操作：

resources :applications do
  resources :applicants do
    put :archived, on: :member
    put :not_archived, on: :member
  end
end

尝试

$('.archive').on('click', function() {
    if ($(this).is(':checked')){
      $.ajax({
            type: "PUT",
            url: '<%= archived_application_applicants_path(:application_id => @application.id) %>',
            data: {id: $(this).attr('id'), archived: true}
    });
    }else {
     $.ajax({
            type: "PUT",
            url: '<%= not_archived_application_applicants_path(:application_id => @application.id) %>',
            data: {id: $(this).attr('id'), archived: true}
    });
    }

});

这可能与您的 javascript 无关。路由器找不到正确的模块/类集来解析将请求发送到哪个控制器。

我的猜测是您的申请者控制器的命名空间如下：

class Applications::ApplicantsController < Superclass;
end

但是applicants_controller.rb 不在app/controllers/applications 中，它需要让Rails 自动创建Applications 模块。移动申请人控制器.rb 或删除命名空间，事情应该会自行解决。
