Module: Sequel::Plugins::Timestamps

Defined in:
lib/sequel/plugins/timestamps.rb

Overview

The timestamps plugin creates hooks that automatically set create and update timestamp fields. Both field names used are configurable, and you can also set whether to overwrite existing create timestamps (false by default), or whether to set the update timestamp when creating (also false by default).

Usage:

# Timestamp all model instances using +created_at+ and +updated_at+
# (called before loading subclasses)
Sequel::Model.plugin :timestamps

# Timestamp Album instances, with custom column names
Album.plugin :timestamps, :create=>:created_on, :update=>:updated_on

# Timestamp Artist instances, forcing an overwrite of the create
# timestamp, and setting the update timestamp when creating
Album.plugin :timestamps, :force=>true, :update_on_create=>true

  • :force - Whether to overwrite an existing create timestamp (default: false)

  • :update - The field to hold the update timestamp (default: :updated_at)
