Rescue, but still log error for Sentry/New Relic notification/logging

Question

Want to log an error that I can use with a Sentry/New Relic, etc. when an error is raised, but I rescue it. Currently I use Sentry and it emails me all raised errors so I can fix them. However, when I rescue the error, no error gets raised, hence no idea anything is wrong.

class Contact
  include ActiveModel::Model
  attr_accessor :name, :email, :message

  validates :name, :phone, :message, presence: true
  validates :email, format: {with: /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i}

  def deliver
    if valid?
      begin
        return ContactUsMailer.contact(self).deliver
      rescue StandardError
        errors.add(:base, I18n.t("messages.unprocessed"))
        # Want to log an error that I can use with a Sentry/New Relic, etc.
        # Currently I use Sentry and it emails me all raised errors to I can fix them.
        false
      end
    end

    false
  end
end

Assuming that you have the sentry-raven gem setup, you can also call

Raven.capture_exception(e)

For your example that should be

class Contact
  include ActiveModel::Model
  attr_accessor :name, :email, :message

  validates :name, :phone, :message, presence: true
  validates :email, format: {with: /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i}

  def deliver
    if valid?
      begin
        return ContactUsMailer.contact(self).deliver
      rescue StandardError => e
        Raven.capture_exception(e)
        errors.add(:base, I18n.t("messages.unprocessed"))
        # Want to log an error that I can use with a Sentry/New Relic, etc.
        # Currently I use Sentry and it emails me all raised errors to I can fix them.
        false
      end
    end

    false
  end
end

to ensure that the issue is still reported to sentry.

If your goal is to just report any text, the answer would be

Raven.capture_message("your text")
