如何使用 Rails 发送确认邮件？

Question

我正在尝试在 rails 4.2.0 应用程序中设置逻辑，在该应用程序中，人们必须先确认其用户帐户，然后才能登录站点/rails 应用程序。基本上，我有一个注册表单，一个人可以在其中输入电子邮件/密码并进行注册。在此过程中，一封带有确认令牌的电子邮件会发送到他们的地址，该确认令牌应为他们提供一个链接以确认其帐户。我不确定如何使用确认令牌，因此它将数据库中的布尔值从 false 更改为 true。我将发布到目前为止我已经实现的内容。

users_controller.rb

    def create
            @user = User.new(user_params)
            if @user.save
                # send confirmation email after user has been created.
                @user.send_confirmation

                session[:user_id] = @user.id
                redirect_to root_url, notice: "Thank you for signing up!"
            else
                render "new"
            end
        end


def confirm
        @user = User.find_by_confirmation_token!(params[:id])
        if @user.update_attributes(confirmed: true)
            redirect_to login_path
        end
    end

confirmation.text.erb

To confirm your account, click the URL below.

<%= user_url(@user.confirmation_token) %>

<%= url_for(controller: 'users', action: 'confirm') %>

If you did not request your account creation, just ignore this email and your account will not be created.

routes.rb

Rails.application.routes.draw do

  resources :articles do
    resources :comments
  end

  get 'resume' => 'resume#index'

  get 'signup' => 'users#new'
  get 'login' =>'sessions#new'
  get 'logout' => 'sessions#destroy'

  # the below route led to a rails routing error
  # get 'confirm' => 'users/:confirmation_token#confirm'

  resources :users
  resources :sessions
  resources :password_resets

  # route to hopefully get confirmation link working :-/
  match '/users/:confirmation_token', :to => 'users#confirm', via: [:post, :get]

  # test route
  match 'users/foo', :to => 'users#foo', via: [:post, :get]

  root "articles#index"

  # Added below route for correct "resumé" spelling
  get 'resumé', :to =>"resume#index"

  # get 'about#index'
  get 'about' => 'about#index'
  get 'contact' => 'contact#contact'

  resources :about
  resources :contact

  match ':controller(/:action(/:id))(.:format)', via: [:post, :get]

我最终将确认逻辑分离到它自己的控制器中，即远离 users_controller.rb 这允许我将以下行添加到我的 routes.rb

resources :confirmations

这允许我编辑 confirmation.text.erb 并将以下链接放入电子邮件中，

<%= edit_confirmation_url(@user.confirmation_token) %>

因此，当一个人收到一封确认其帐户的电子邮件时，它会路由到确认控制器的编辑操作，该编辑操作称为更新操作，并确认帐户。控制器如下所示，

confirmations_controller.rb

class ConfirmationsController < ApplicationController

    def new
    end

    def edit
        @user = User.find_by_confirmation_token!(params[:id])
        update
    end

    def update
        # @user = User.find_by_confirmation_token!(params[:id])
        if @user.confirmation_sent_at < 2.hours.ago
            redirect_to new_confirmation_path, :alert => "Confirmation has expired."
        # elseif @user.update_attributes(params[:user])
        elsif @user.update_attributes(confirmed: true)
            redirect_to root_url, :notice => "Your account has been confirmed."
        else
            render :new
        end
    end
end
