How do I setup UUID / GUID for Model primary keys ?

[Kevin Baker]

How would I go about setting up a custom schema in a Sails Model to allow for UUID's for the "id" primary key?

I would love to do something like this.

```

attributes: {

  id: {

    type: 'uuid',

    required: true

  }

}

```

Or just `id: 'string' with a beforeCreate generateUUID filter at the end.

Would this work? Is there a best practice?

Thanks

BTW: did see one other post on this, but there didn't seem to be a resolution. Thanks for your help.

I don't know that Waterline supports this so I'd recommend the second approach, use an id: with type 'string' and assign a UUID with a beforeCreate hook.

Great, I just found the StackOverflow post: http://stackoverflow.com/questions/21386573/how-can-i-write-sails-function-on-to-use-in-controller. That has details on how to do exactly what you describe.

I found this helpful too in the Waterline docs: https://github.com/balderdashy/waterline-docs/blob/master/models.md (search for uuid)

Thanks for the guidance!
