#call_api_with_retry(options = {}) ⇒ Object

Yields a block and retries on retriable errors n times. The raised error could be the defined retriable or it child.

Example:

class PizzaService
  include Take2

  number_of_retries 3
  retriable_errors Net::HTTPRetriableError
  retriable_condition proc { |error| response_status(error.response) < 500 }
  on_retry proc { |error, tries| puts "#{self.name} - Retrying.. #{tries} of #{self.retriable_configuration[:retries]} (#{error})" }    
  sleep_before_retry 3

  def give_me_food
    call_api_with_retry do
      # Some logic that might raise..
      # If it will raise retriable, magic happens.
      # If not the original error re raised
    end
  end

end
