Overriding id on create in ActiveRecord

Question

Is there any way of overriding a model\'s id value on create? Something like:

Post.create(:id => 10, :title => \'Test\')

would be ide

Answer 1

As Jeff points out, id behaves as if is attr_protected. To prevent that, you need to override the list of default protected attributes. Be careful doing this anywhere that attribute information can come from the outside. The id field is default protected for a reason.

class Post < ActiveRecord::Base

  private

  def attributes_protected_by_default
    []
  end
end

(Tested with ActiveRecord 2.3.5)
