Configure OmniAuth logger to two different loggers depending the level of the error

Question

In my Rails 5 app I have 'omniauth', '~> 2.0.3' where in my config config/initializers/omniauth.rb I'm attaching the logger to the Rails.logger.

OmniAuth.config.logger = Rails.logger

What I want to do is if the log level is error I want to use Rollbar instead of the Rails logger.

Is there a way to do this?

Answer 1

you can create a proxy logger which delegate error level logs to Rollbar, other levels will delegate to Rails.logger

class ProxyLogger
  delegate :error, to: :@error_logger
  delegate_missing_to :@default_logger

  def initialize(error_logger:, default_logger: Rails.logger)
    @default_logger = default_logger
    @error_logger = error_logger
  end
end

OmniAuth.config.logger = ProxyLogger.new(error_logger: Rollbar)
