sequelize.js custom validator, check for unique username / password

Question

Imagine I have defined the following custom validator function:

isUnique: function () { // This works as expected
  throw new Error({error:[{message:\'Email addr         


        

Answer 1

Success callback is called even if no user is found. You have to check if the function passes a user as an argument:

isUnique: function (email) { // This doesn't work
  var User = seqeulize.import('/path/to/user/model');

  User.find({where:{email: email}})
    .success(function (u) { // This gets called
      if(u){
        throw new Error({error:[{message:'Email address already in use!'}]});  // But this isn't triggering a validation error.
      }
    });
}
