batches: each with named_scope doesn't seem to work

Reported by Carlos Antonio da Silva | March 10th, 2009 @ 07:38 PM

I've been testing the new find_in_batches and each methods with named_scopes, and verified that the each method actually does not seem to work correctly. While find_in_batches uses the named_scope in the right way, the each method instead is executing the query and using the each method from Enumerable.

To demonstrate it:

class Person < ActiveRecord::Base

  named_scope :all_active, :conditions => { :active => true }

  def process_something
    # Process

# This works as expected
Person.all_active.find_in_batches do |people_batch|
  people_batch.each { |person| person.process_something  }

# This doesn't work
Person.all_active.each do |person|

I guess the each method should work fine as find_in_batches, and for those who want to iterate over the array of records from named_scope call, could use something like:

Person.all_active.all.each do |person|
