Blame

Automatically userstamps create and update operations if the table has columns named created_by and/or updated_by. The Blame plugin attempts to mirror the simplicity of ActiveRecord’s timestamp module.

Blame adds a userstamps migration helper which will create both created_by and updated_by columns in your table:

create_table :widgets do |t|
  t.string :name
  t.timestamps
  t.userstamps
end

Blame assumes that you are using restful-authentication and defaults to looking for the current user in User.current_user. You can override this behavior by writing your own userstamp_object method in ActiveRecord::Base or any of your models. For example:

def userstamp_object
  User.find(session[:user_id])
end

You can change the names of the userstamp columns:

# Globally in environment.rb
ActiveRecord::Base.created_userstamp_column = :creator_id

# In a model definition
class Subscription
  self.created_userstamp_column = :creator_id
  self.updated_userstamp_column = :updater_id
end

Automatic userstamping can be turned off globally by setting:

ActiveRecord::Base.record_userstamps = false
