How do I handle a Unique Field in sails?

Question

I\'ve defined a unique field in my model but when I tried to test it seems like it\'s not being checked by sails because I get a Error (E_UNKNOWN) :: Encountered an un

You are trying to create two users with the same email address after defining the email as a unique field.

Maybe you can query for a user by that email address - if it exists already - return an error or update that user.

var params = {email: 'email@email.com'};

User.findOne(params).done(function(error, user) {

  // DB error
  if (error) {
    return res.send(error, 500);
  }

  // Users exists
  if (user && user.length) {

    // Return validation error here
    return res.send({error: 'User with that email already exists'}, 403.9);
  }

  // User doesnt exist with that email
  User.create(params).done(function(error, user) {

    // DB error
    if (error) {
      return res.send(error, 500);
    }

    // New user creation was successful
    return res.json(user);

  });

});

There is also an interesting bit about unique model properties in the Sails.js docs https://github.com/balderdashy/waterline#indexing

Available validations are:

empty, required, notEmpty, undefined, string, alpha, numeric, alphanumeric, email, url, urlish, ip, ipv4, ipv6, creditcard, uuid, uuidv3, uuidv4, int, integer, number, finite, decimal, float, falsey, truthy, null, notNull, boolean, array, date, hexadecimal, hexColor, lowercase, uppercase, after, before, is, regex, not, notRegex, equals, contains, notContains, len, in, notIn, max, min, minLength, maxLength
