Put 链接\u以更新嵌套资源不工作

_applicator.html.erb中的链接在浏览器中如下所示：

http://localhost:3000/needs/3/applicants.1

单击此按钮后，浏览器中将显示：

Routing Error

No route matches [PUT] "/needs/3/applicants.1"

我希望它更新此特定申请人行的“接受”列。基本上，我希望它将数据发送到应用程序控制器的更新方法。如何修改代码以实现此目的

_applicator.html.erb

<%= link_to 'Accept Applicant', need_applicants_path(applicant.need_id, applicant.id), :method => :put, :action => "update", :applicant => {:acceptance => true} %>

routes.rb：

resources :needs, except: [:new] do
 resources :applicants
end

申请人(u controller.rb)

class ApplicantsController < ApplicationController

  def update
    @need = Need.find(params[:need_id])
    @applicant = @need.applicants.find(params[:id])

    if @applicant.update_attributes(params[:applicant])
      flash[:success] = 'Your applicant has been accepted/rejected!'
      redirect_to @need
    else
        @need = Need.find(params[:need_id])
      render 'needs/show'
    end

  end


end

类应用程序控制器

我认为这里有两种可能的修复方法：

首先,

http://localhost:3000/needs/3/applicants.1

应该读一下

http://localhost:3000/needs/3/applicants/1

错误在这一行：

<%= link_to 'Accept Applicant', need_applicants_path(applicant.need_id, applicant.id), :method => :put, :action => "update", :applicant => {:acceptance => true} %>

您可以尝试传入两个实例对象，如下所示：

need_applicants_path(Need.find(applicant.need_id), applicant)

其次，另一种可能的解决方案是在路由中显式设置PUT路径

在config/routes.rb中添加行

put 'need/:need_id/applicant/:id/update

然后跑

rake routes

---

然后看看PUT路径是什么

嘿，谢谢Rich。最后我做了这个，它开始工作了：applicator.need_id，：applicator_id=>applicator.id，：applicator=>{:accepted=>true}），：method=>:put，：action=>“update”%>

put 'need/:need_id/applicant/:id/update

rake routes
