Read the original article Hit count: 162

 Contract.all(:conditions => ['voided == ?', 0]).size
 => 364
 Contract.all(:conditions => ['voided != ?', 0]).size
 => 8
 Contract.all.size
 => 441

the 3 numbers does not added up (364 + 8 != 441). What's the proper way write the :conditions to count the rows which the voided column value is NULL or equal to zero?
