如何在Rails3.1上用Devise更改電子郵件地址

Question

我想要一個「編輯個人資料」頁面，用戶可以在其中註冊時更改註冊的電子郵件地址。

我想有以下過程：

• 用戶必須輸入自己的密碼，以確認他讓在電子郵件領域的變化之前。
• 提交該頁面後，用戶應該收到驗證郵件，就像Devise的默認註冊一樣。
• 只要用戶單擊郵件上的驗證令牌URL，電子郵件更改就會完成。

我該怎麼做？

Answer 1

我爲我的一個網站創建了同樣的流程。下面是你可以做什麼的例子：

添加到config/routes.rb中 （請注意，路由可能會更好，但我前一陣子這樣做）

scope :path => '/users', :controller => 'users' do 
    match 'verify_email' => :verify_email, :as => 'verify_email' 
    match 'edit_account_email' => :edit_account_email, :as => 'edit_account_email' 
    match 'update_account_email' => :update_account_email, :as => 'update_account_email' 
end 

增加應用程序/控制器/ users_controller.rb

def edit_account_email 
    @user=current_user 
end 

def update_account_email 

    @user=current_user 
    @user.password_not_needed=true 
    @user.email=params[:address] 

    if @user.save 
    flash[:notice]="your login email has been successfully updated." 
    else 
    flash[:alert]="oops! we were unable to activate your new login email. #{@user.errors}" 
    end 
    redirect_to edit_user_path 

end 

def verify_email 

    @user=current_user 
    @address=params[:address] 

    UserMailer.confirm_account_email(@user, @address).deliver 

end 

應用程序/郵寄者/ user_mailer.rb

class UserMailer < ActionMailer::Base 

    def confirm_account_email(user, address) 

    @user = user 
    @address = address 

    mail(
    :to=>"#{user.name} <#{@address}>", 
    :from=>"your name <'your_email@domain.com'>", 
    :subject=>"account email confirmation for #{user.name}" 
    ) 

    end 

end 

應用程序/視圖/ user_mailer文件/ confirm_account_email.html.erb

<p>you can confirm that you'd like to use this email address to log in to your account by clicking the link below:</p> 

<p><%= link_to('update your email', update_account_email_url(@user, :address=>@address)) %></p> 

<p>if you choose not to confirm the new address, your current login email will remain active.
