Module: BigRecord::Timestamp

Defined in:
lib/big_record/timestamp.rb

Overview

Big Record automatically timestamps create and update if the table has fields created_at/created_on or updated_at/updated_on.

Timestamping can be turned off by setting 

  <tt>BigRecord::Base.record_timestamps = false</tt>

Keep in mind that, via inheritance, you can turn off timestamps on a per model basis by setting record_timestamps to false in the desired models. 

  class Feed < BigRecord::Base
    self.record_timestamps = false
    # ...
  end

Timestamps are in the local timezone by default but can use UTC by setting 

  <tt>ActiveRecord::Base.default_timezone = :utc</tt>
