我尝试了以下代码片段，以便在设计时自定义重置密码
class CustomMailer < Devise::Mailer
helper :application # gives access to all helpers defined within `application_helper`.
include Devise::Controllers::UrlHelpers # Optional. eg. `confirmation_url`
default template_path: 'devise/mailer' # to make sure that your mailer uses the devise views
def reset_password_instructions(record, token, opts={})
@resource = record
mail(:to => "#{@resource.full_name} <#{@resource.email}>", :subject => "Reset password instructions", :tag => 'password-reset', :content_type => "text/html") do |format|
format.html { render "devise/mailer/reset_password_instructions" }
end
end
端
并在 Devise.rb 中定义为
config.mailer = 'CustomMailer'
哪个在本地机器/ dev env上完全正常，但在生产中我收到的错误如下：

您是否在config / environments / production.rb中设置了smtp设置？
