When you use set_primary_key, ActiveRecord maps your key to the attribute "id" behind the scenes. So you still use "id".

The primary key attribute is protected from mass assignment, so can't be set by passing its value in a hash. Try this instead:

i = Inc.new("name" => "to inc or not to inc?") i.id = 123 i.save
