User defined id

Hi there,

I'm just starting a new project with Cakephp but I'm stuck with a very basic problem.

I have a "countries" table that looks like this:

CREATE TABLE `countries` (  `id` varchar(7) NOT NULL DEFAULT '',  `name` varchar(255) NOT NULL DEFAULT '',  `description` varchar(255) NOT NULL DEFAULT '',  PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

As you can see want to use a VARCHAR as primary key as I want to use a customized country code as primary key (e.g. FR-2013, DE-2010, ES-2010 etc), I also want users to be able to manually insert this code. I know using a non-numeric id is not recommended but I have my reasons.

Now, when I create a form to add data (I want users to be able to add new countries), the `id` field is automatically hidden, I could probably come up with a workaround but I was wondering if there a "proper" way to do it.

I also have other tables where I have a similar situation.

Thanks,
Eros
