named_scope_for_time_attr

All information can be found here: nsfta.rubyforge.org/

DESCRIPTION:

Provides the ActiveRecord helper method named_scope_for_time_attr.

Given the name of a time attribute of an ActiveRecord model (e.g. created_at of Claim) it defines a correspondent named scope for easy access to an arbitrarily time range (scope).

FEATURES/PROBLEMS:

  • Defines a named scope for the given time attribute

  • Allows easy access to an arbitrarily time range

  • Defines a named scope order for easy ordering of the result

SYNOPSIS:

Define the named scope created_at and last_modified_on via named_scope_for_time_attr: 

class Claim < ActiveRecord::Base
  named_scope_for_time_attr :created_at, :order => 'created_at DESC'
  named_scope_for_time_attr :last_modified_on, :limit => 10
  ...
end

It is then possible to use the scope method created_at and updated_at as follows:

Claim.created_at(2.days.ago)
Claim.created_at(2.days.ago, 1.days.ago)
Claim.created_at(:today)
Claim.created_at(:this_month).order('created_at DESC')
Claim.created_at(:q1) # quarter one
Claim.last_modified_on(3.weeks.ago, :limit => 20)
...
