How to pre-define/generate a unique ID in sails.js?

Question

I'm using sails.js and mySQL db to build a website. For solving this particular problem, I have thought of pre-defining my ID attribute of my model(taking care of uniqueness by using the timestamp). So once I create a record with the ID that I've defined, I will be able to associate the files(which I upload using JQuery file upload plugin) with this particular record that I created. But I am not sure how to do this in sails.js. Is this possible?

Or can I just define a separate attribute which will have the property unique: true and generate it on front end and pass it over to backend and use this attribute to associate my files.

If I'm understanding your question correctly, then yes, you can define your own primary key to be used instead of an automatically generated ID.

myAwesomeId: {
    type: 'string',
    unique: true,
    required: true,
    primaryKey: true
},
// other attributes
