设计用户内的路由问题

Question

我对 Rails 还很陌生，我在一个新的演示应用程序中使用 Devise 进行用户身份验证。我已经让 Devise 工作了，还有可确认的模块和电子邮件验证。

我现在正尝试在此基础上构建电话验证。我更新了 User 模型，增加了三个字段：phone_number、phone_verified（布尔值）和 phone_verification_code。我还更新了 Registrations Controller 以允许 User 模型的 phone_number 附加字段。

现在，为了设置电话验证系统，我通过在 UsersController 中添加验证方法并更新 routes.rb 来创建页面 /user/:id/verify。当我输入 URL http://localhost:3000/users/10/verify 时，我会看到该页面的视图。

但是，我试图通过在 /app/views/users/show.html.erb 上创建一个按钮来访问该视图，并且我的下面的代码出现错误。我正在尝试为按钮获取正确的路径助手。有人可以帮忙吗。

这是错误：

显示第 10 行引发的 /home/ubuntu/work/depot/app/views/users/show.html.erb：

#的未定义方法`verify_user_path'

app/views/users/show.html.erb

<p id="notice"><%= notice %></p>

<div class="row">
    <div class="col-md-offset-2 col-md-8">
        <div class="panel panel-default">
            <div class="panel-heading"><%= @user.email %></div>
                        <div class="panel-body">
                                <strong>Phone number: </strong><%= @user.phone_number %><br/>
                                <% if @user.phone_verified == nil %>
                                    <%= button_to [:verify, @user] do %>
                                        Verify Phone <strong><%= @user.phone_number %></strong>
                                    <% end %>
                                <% else %>
                                    <strong>Phone Verified: </strong><%= @user.phone_verified %><br/>
                                <% end%>
                        </div>

UsersController

 class UsersController < ApplicationController

  def index
    @users = User.all
  end

  def show
    begin
      @user = User.find(params[:id])
    rescue ActiveRecord::RecordNotFound
      logger.error "Attempt to access an invalid user: #{params[:id]}"
      redirect_to store_url, notice: "Attempt to access an invalid user: #{params[:id]}"
    else
      respond_to do |format|
        format.html # show html.erb
        format.json { render json: @user }
      end
    end
  end

  def verify
  end

  def generate_pin
    @user.phone_verification_code = rand(0000..9999).to_s.rjust(4, "0")
    save
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_user
      @user = User.find(params[:id])
    rescue ActiveRecord::RecordNotFound
      @user = nil
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def user_params
      params[:user]
    end

end

routes.rb

Rails.application.routes.draw do
  devise_for :users, controllers: { registrations: "registrations" }
  resources :users, only: [:index, :show, :edit, :update] 
  resources :orders
  resources :line_items
  resources :carts
  match "users/:id/verify" => "users#verify", via: [:get]
  get 'store/index'

  resources :products
  # The priority is based upon order of creation: first created -> highest priority.
  # See how all your routes lay out with "rake routes".

  # You can have the root of your site routed with "root"
  # root 'welcome#index'
  root 'store#index', as: 'store'

Answer 1

您需要在路由中使用as 选项：

match "users/:id/verify" => "users#verify", via: [:get], as: 'verify_user'

然后重新启动您的服务器。这将告诉 Rails 创建正确的 URL 辅助方法：verify_user_path 和 verify_user_url

Answer 2

match "users/:id/verify" => "users#verify", as: 'verify_user',  via: [:get]

或者更好的方法：

resources :users, only: [:index, :show, :edit, :update] do
  get :verify
end
