How can I include a :select clause with find_in_batches. The following
throws an error " Mysql::Error: Unknown column ‘users.id’ in ‘field
list’: .
Post.find_in_batches(:batch_size => 100, :select => "users.id,
users.name, categories.name, posts.id", :include =>
[:user, :category]) do |group|
#stuff with group
end
