[Nitro] [PATCH] bundle for Og, sql and validation

[Jonathan Buch]

Hi,

Tue Mar 20 12:44:10 EET 2007  Jonathan Buch <jo at helloit.fi>
   * sql.rb changes
   * remove duplicated write_attrs
   * made write_attr_boolean return 'f' instead of NULL
   * fix require in tc_timestamped
   * add :extra_condition to .find (for use with set_find_options())
     i.e. set_find_options(:extra_condition => 'time_deleted IS NULL')
   * fix validate_format
   * :where is now handled together with :condition in find()


use case for :extra_condition

module Preserved
   attr_accessor :time_deleted, Time
   set_find_options(:extra_condition => 'time_deleted IS NULL')

   alias_method :force_delete, :delete
   def delete
     @time_deleted = Time.now
     save
   end

   def undelete
     @time_deleted = nil
     save
   end
end

class Foo
   is Preserved
end

Foo.find()  # => only finds non-deleted Foos
