我正在尝试使用带有 Rails 的设计发送重置密码说明。用户单击“忘记密码链接”，然后输入他们的电子邮件地址以接收重置密码说明。我看到电子邮件已在开发日志中发送，但我没有收到我的测试电子邮件，并且我看到下面的错误。关于我做错了什么的任何想法？
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
我正在开发中进行测试，所以我的 development.rb 有以下内容：
# 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
}
在 user.rb 中，我有以下内容：
def send_reset_password_instructions
UserMailer.reset_password_instructions(self.email).deliver
end
正如我上面提到的，我看到在超时之前正在日志中生成电子邮件 - 下面是完整的堆栈跟踪：
