在production.rb中，我有以下单行的config.action_mailer ..
config.action_mailer.default_url_options = { :host => 'secret-brushlands- 1375.herokuapp.com' }
在Development.rb中我（这似乎工作BTW）
config.action_mailer.perform_deliveries = true
config.action_mailer.default_url_options = { :host => 'localhost:3000'}
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {:address => "localhost", :port => 1025}
在Environment.rb中我有：
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['sendgrid user'],
:password => ENV['sendgrid password'],
:domain => 'heroku.com',
:enable_starttls_auto => true
}
我们很抱歉，但出了点问题。
出于某种原因，我的heroku应用程序出现此错误（仅限于此 当我尝试sign_up时，用户部分发生了另一个模型 postgresql上的功能似乎很酷） - 我做了一个heroku PG：复位 heroku运行rake：db：migrate等等但无济于事。
这是我的宝石文件：

在config/environment.rb文件中，更改smtp_settings的配置如下：
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['SENDGRID_USERNAME'], ## Refer to key SENDGRID_USERNAME
:password => ENV['SENDGRID_PASSWORD'], ## Refer to key SENDGRID_PASSWORD
:domain => 'heroku.com',
:enable_starttls_auto => true
}
之后，通过运行以下命令在heroku环境中添加环境变量SENDGRID_USERNAME和SENDGRID_PASSWORD：
heroku addons:add sendgrid:starter
