Ruby on rails 使用designe发送重置密码指令

我正在尝试使用Desive with Rails发送重置密码指令。用户单击“忘记密码链接”，然后输入其电子邮件地址以接收重置密码说明。我看到电子邮件在开发日志中发送，但我没有收到我的测试电子邮件，我看到下面的错误。你知道我做错了什么吗

Timeout::Error - execution expired

在user_mailer.rb中，我有以下内容：

class UserMailer < ActionMailer::Base
 include Devise::Mailers::Helpers

 default :from => ENV["EMAIL_ADDRESS"]

 def reset_password_instructions(record, opts={})
  mail(:to => record, :subject => "Reset Password Instructions")
 end

end

# ActionMailer Config
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
# change to true to allow email to be sent during development
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"

config.action_mailer.smtp_settings = {
:address   => "smtp.mandrillapp.com",
:port      => 25,
:user_name => ENV["MANDRILL_USERNAME"],
:password  => ENV["MANDRILL_API_KEY"],
:enable_starttls_auto => true, # detects and uses STARTTLS
:authentication => 'login', # Mandrill supports 'plain' or 'login'
:domain => 'mydomain.com', # your domain to identify your server when connecting
}

def send_reset_password_instructions
 UserMailer.reset_password_instructions(self.email).deliver
end

在user.rb中，我有以下内容：

class UserMailer < ActionMailer::Base
 include Devise::Mailers::Helpers

 default :from => ENV["EMAIL_ADDRESS"]

 def reset_password_instructions(record, opts={})
  mail(:to => record, :subject => "Reset Password Instructions")
 end

end

# ActionMailer Config
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
config.action_mailer.delivery_method = :smtp
# change to true to allow email to be sent during development
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"

config.action_mailer.smtp_settings = {
:address   => "smtp.mandrillapp.com",
:port      => 25,
:user_name => ENV["MANDRILL_USERNAME"],
:password  => ENV["MANDRILL_API_KEY"],
:enable_starttls_auto => true, # detects and uses STARTTLS
:authentication => 'login', # Mandrill supports 'plain' or 'login'
:domain => 'mydomain.com', # your domain to identify your server when connecting
}

def send_reset_password_instructions
 UserMailer.reset_password_instructions(self.email).deliver
end

正如我上面提到的，我在日志中看到电子邮件在超时之前生成-下面是完整的堆栈跟踪：

您是否已成功使用Mandrill帐户发送电子邮件？我建议尝试在开发中发送邮件。如果这样做有效，您可以开始缩小配置中的问题范围。谢谢-我尝试了MailCatcher，虽然我没有通过电子邮件收到消息，但它显示消息已正确发送。有关于排除mandrill配置故障的想法吗？我已经有一段时间mailchimp可以很好地处理欢迎信息和向普通电子邮件活动添加用户，但还没有弄清楚事务性电子邮件。ThanksMailCatcher截获发送的邮件，并将其放在web界面中，这样您就不应该收到它。相反，您应该能够在浏览器中的127.0.0.1:1080处看到它。至于Mandrill，我相信您仍然需要在主机上设置postfix或其他smtp接口，如果您还没有这样做的话。这是一个相当普遍的问题，所以你应该能够谷歌的细节或您的操作系统设置。
