                        root GET    /                                           high_voltage/pages#show {:id=>"index"}

配置/ routes.rb中

Rails.application.routes.draw do
      devise_for :users

      resources :users do
        resources :contacts
      end
    end

我在new

中的create和ContactsController行动

     def new
        @contact = Contact.new
      end

      def create
        @contact = Contact.new(contact_params)
        @contact.user = current_user
        if @contact.save
          flash[:success] = "Contact was successfully created!"
          redirect_to @contact.user
        else
          render :new
        end
      end

这是问题所在：当我在http://localhost:3000/users/1/contacts/new提交表单时收到错误：No route matches [POST] "/users/1/contacts/new"。可能是什么问题？

Answer 1

此：

 <%= simple_form_for @contact, :url => new_user_contact_path do |f| %>

应该是：

 <%= simple_form_for @contact, :url => user_contacts_path do |f| %>

没有路由匹配[POST]“/ users / 1 / contacts / new”
