我正在尝试首次将我的rails 3应用程序部署到heroku，但它一直在向我扔uninitialized constant Mail::TestMailer (NameError)，这是日志文件

我的Gemfile看起来像这样

由于我正在使用设计来处理用户注册，所以我认为设计会尝试发送确认电子邮件。但是我在production.rb之后添加了action_mailer的一些配置，就像这样
config.action_mailer.raise_delivery_errors = false
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
tls: true,
domain: 'gmail.com',
user_name: 'secret@email.com',
password: 'secret',
authentication: 'plain',
enable_starttls_auto: true
}
它还没有给我错误
提前致谢

重命名邮件模型时，请务必重命名文件app / models / mail.rb并添加迁移以重命名邮件表以匹配新模型。
