在ActionMailer中禁用某些电子邮件

Question

I would like to turn off certain emails in development and on test/staging servers, but keep sending them in production. What I currently do is set the default "to" address for these administrative mails to blank:

  default :to => Rails.env.production? ? "admin-list@sharethevisit.com" : ""

However, this puts stack traces in my development log when I'm testing the user mails which should be sending.

Is there a more effective way of disabling certain emails based on the current environment? I tried checking in the functions themselves, but is not ideal because I have to change each function, plus it doesn't actually work... it just fails to set the needed @account variable before rendering the email and creating a different stack trace.

  def user_registered_notify_email(account)
    if Rails.env.production?
      @account = account
      mail(:subject => "New user registered: #{@account.full_name}")
    end
  end

Answer 1

I can't remember where I found this to credit the author but this is how I redirected email in development mode. Create a new file in RAILS_ROOT/config/initializers for this. DEFAULT_DEV_EMAIL_OVERRIDE is defined in our main site config with other static values.

if Rails.env.development?
  if Rails.version =~ /^2\./
    class ActionMailer::Base
      def create_mail_with_overriding_recipients
        mail = create_mail_without_overriding_recipients
        mail.to = DEFAULT_DEV_EMAIL_OVERRIDE
        mail
      end
      alias_method_chain :create_mail, :overriding_recipients
    end
  elsif Rails.version =~ /^3\./
    if Rails.env.development?
      class OverrideMailRecipient
        def self.delivering_email(mail)
          mail.to = DEFAULT_DEV_EMAIL_OVERRIDE
        end
      end
      ActionMailer::Base.register_interceptor(OverrideMailRecipient)
    end
  end
end

我通常按​​照以下说明使用邮件拦截器： http : //asciicasts.com/episodes/206-action-mailer-in-rails-3

Answer 3

Consider using an interceptor to set Mail::Message#perform_deliveries to false :

class NeverDeliverInterceptor
  def self.delivering_email(message)
    message.perform_deliveries = false
  end
end

if !Rails.env.production?
  ActionMailer::Base.register_interceptor(NeverDeliverInterceptor)
end
