Question

Rails 2.2.2 didn’t have find_in_batches functionality (or find_each).

Is there a plugin that provides this? I haven’t been able to find one.

Answer 1

You can use paginated_each from will_paginate to achieve this. It can be used as a gem or a plugin.

For example:

MyClass.paginated_each(:per_page => 100) do |obj|

end

will load your objects in batches of 100.
