ruby-on-rails - 无法为 ActionMailer::Base 找到 Rails 3 "The action ' 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。

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

application.rb

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 (The action 'method' could not be found for ActionMailer::Base):
app/mailers/notifier.rb:1:in <top
(required)>'

app/controllers/users_controller.rb:17:in

Answer 1

它是

config.action_mailer.delivery_method

不是

config.action_mailer.deliver_method

.

我今天碰巧在我的配置中犯了同样的错字。
