您好我正在尝试使用一些数据初始化 ActionMailer::Base:Class:
ActionMailer::Base.add_delivery_method :ses, AWS::SES::Base,
:access_key_id => '0PxxxxxxxxxxxxS8Dyyy',
:secret_access_key => 'aJxxxxxxxxxxxxx2Tpppa+ZQ6dddddddkN2'
但这会引发错误:
`method_missing': undefined method `add_delivery_method' for ActionMailer::Base:Class (NoMethodError)
我的 Rails 版本 -3.2.13
我究竟做错了什么?
