Question

一切都进展顺利......

已安装gem'mail'

输入＆gt; $ rails g scaffold用户名：string email：string

输入＆gt; $ rake db：migrate（很好，我可以在http://localhost:3000/users/new上看到）然后......

输入＆gt; $ rails g mailer user_mailer

在这个命令中我得到了这个巨大的错误 - 它是什么以及如何解决它？

以下是我的config / initializers / setup_mail.rb

的内容

使用Heroku和Sendgrid并安装了插件。

我是否需要先安装'mail'gem，文档中没有提到它？

ActionMailer::Base.smtp_settings = {
:address        => "smtp.sendgrid.net",
:port           => "25",
:authentication => :plain
:user_name      => "apxxxxx@heroku.com",
:password       => "9XXXXXXXXX",
:domain         => "www.myapp.com",
}

我知道现在的问题 - 用户名和密码条目后没有逗号！
