通过本地主机发送确认电子邮件注册用户的ROR应用(Sending confirmation emai

在我的ROR应用程序，我想发送确认电子邮件到我的注册用户，当他们注册，我的网站是在本地主机上当前。 我得到这个错误：

"undefined method `recipients' for #<UserMailer:0x3d841a0>"

这里是我的代码;

development.rb

config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { :host => "localhost:3000"}
config.action_mailer.smtp_settings = {
      :address      => "smtp.gmail.com",
      :port          => "587",
      :authentication => :login,
      :user_name      => "[e-mail]",
      :password       => "myrealpassword"
}  

Users_controller.rb

def new
  UserMailer.registration_confirmation(@user).deliver
end

def create
  @user = User.new(params[:user])
  if @user.save
    UserMailer.registration_confirmation(@user).deliver
    sign_in @user
    flash[:success] = "Welcome!"
    redirect_to @user
  else
    render 'new'
  end
end

user_mailer.rb

class UserMailer < ActionMailer::Base   
  def registration_confirmation(user)
    recipients   user.email
    from         "[e-mail]"
    subject      "Thank you for registration"
    body         :user => user  
  end
end

Answer 1:

** ** development.rb

config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true

** ** Users_controller.rb

def new
  UserMailer.registration_confirmation(@user).deliver
end
def create
  @user = User.new(params[:user])
  if @user.save
    UserMailer.registration_confirmation(@user).deliver
    sign_in @user
    flash[:success] = "Welcome!"
    redirect_to @user
  else
    render 'new'
  end
end

** ** User_mailer.rb

 def registration_confirmation(user) 
   @message = 'whatever you want to say here!'
   mail(:from => "[e-mail]", :to => user.email, :subject => "Thank you for registration")
end

** /应用/视图/ user_mailer文件/ registration_confirmation.text.erb *

<%= @message %>

这就是我在发展模式所做的，和它的作品

Answer 2:

您正在使用什么版本的Rails的？

电子邮件发送3.2版本改变（我相信）

http://api.rubyonrails.org/classes/ActionMailer/Base.html

尝试：

UserMailer.registration_confirmation(@user).deliver

Answer 3:

这是你的user_mailer.rb

user_mailer.rb

class UserMailer < ActionMailer::Base
  def registration_confirmation(user)
    recipients   user.email
    from         "[e-mail]"
    subject      "Thank you for registration"
    body         :user => user  
  end

尝试改为：

class UserMailer < ActionMailer::Base
  default from: "[e-mail]"

  def registration_confirmation(user)
    mail(to: user.email, subject: "Thank you for registration")
  end
end

并成立了意见/ user_mailer文件如registration_confirmation.html.erb相应的视图
