Ruby on rails Ajax POST请求上的Rails 404，尽管定义了路由

我正在跑步：

轨道6 Ruby 2.5 博士后11.5 MacOSX

我定义了以下路线：

Rails.application.routes.draw do
  get 'welcome/index'
  # For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html
  root 'welcome#index'

  post 'search_controller/search'
end

我认为有以下代码：

 <%= form_for :search, :url => url_for(:controller => 'search_controller', :action => 'search'), remote: true do |f| %>
  <%= f.text_field :search_term %>
  <%= f.submit %>

当我运行

rails routes

时，我得到：

请注意，您可以在search\u controller\u search处查看路由

考虑到这些细节，我为什么要得到404？

问题在于路由定义

解决办法是改变：

 post 'search_controller/search'

致：

我将查看呈现的页面的源代码，并验证URL是否符合预期。此外，请查看提交表单时生成的服务器日志-它是否收到了您认为应该收到的内容？首先根据rails 6 way编写路线代码和

@dinjas我甚至没有从服务器上看到错误，根本没有问题，这很奇怪。我使用：
foreman start-f Procfile.dev运行服务器，Procfile.dev有：web:bundle exec puma-C config/puma.rb webpacker:./bin/webpack dev-server@nileshkumar我现在也试过了——没有帮助，也有同样的问题——你的建议没有帮助。
