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

Post.create!(:title => "Test") { |t| t.id = 10 }

This doesn't strike me as the sort of thing that you would normally want to do, but it works quite well if you need to populate a table with a fixed set of ids (for example when creating defaults using a rake task) and you want to override auto-incrementing (so that each time you run the task the table is populate with the same ids):

post_types.each_with_index do |post_type|
  PostType.create!(:name => post_type) { |t| t.id = i + 1 }
end
