Rails 3“无法找到ActionMailer :: Base的动作'方法'

Question

无法在rails 3中发送邮件。在浏览器中显示以下消息。

Unknown action

The action 'method' could not be found for ActionMailer::Base

这是我写的代码。

1. Notifier.rb

class Notifier < ActionMailer::Base 
  default :from => "xxxxx@gmail.com"
  default_url_options[:host] = "localhost.com:3000"


def welcome_email(user)
 @user_email = user @url = root_url mail(:to => user.email, :subject => "Welcome to the site") end end 

2.UsersController.rb

 Notifier.welcome_email(@user).deliver

1. application.rb中

config.action_mailer.deliver_method = :smtp
    config.action_mailer.smtp_settings = {
      :address => "smtp.gmail.com",
      :port => 587,
      :domain => 'xxxxxxx.com',
      :user_name => 'xxxx@gmail.com',
      :password => 'xxxx',
      :authentication => 'plain',
      :enable_starttls_auto => true
    } 

这是日志消息

AbstractController :: ActionNotFound（无法在ActionMailer :: Base中找到操作'method'）：
app / mailers / notifier.rb：1：in <top (required)>'
app/controllers/users_controller.rb:17:in <top (required)>'
app/controllers/users_controller.rb:17:in <top (required)>'
app/controllers/users_controller.rb:17:in create'

在救援/布局中呈现C：/Ruby192/lib/ruby/gems/1.9.1/gems/actionpack-3.0.5/lib/action_dispatch/middleware/templates/rescues/unknown_action.erb(0.0ms）

Answer 1

它的

config.action_mailer.delivery_method

不

config.action_mailer.deliver_method

。

我今天在配置中遇到了相同的拼写错误。
