Sails JS: what is the unique validator for?

Question

Node.js

I sent the form to sails, and the data is duplicated in MongoDB, even though I set the unique property. Either I did not understand what it was for, or I did not write something correctly.

userName: {
      type: 'string',
      unique: true,
      required: true
    }

Explain, please. Thanks

Perhaps the point is that you have migrate: 'safe' in your waterline configs, in which case migrations are not performed and indexes, respectively, are not created. Try migrating: 'alter' (only if not in a production environment!) or setting the indexes manually.
