How validate nested models on Loopback

[rkmax]

I'm confused if nested validation it's supported, how it works and if it's possible do the situation described below

I have the following models

• Customer based on PersistedModel
  • contact property type ContactInfo
  • address property type Address
  • ...
• ContactInfo based on Model
  • emailAddress property type string
  • phoneNumber property type string
  • firstName property type string
  • lastName property type string
• Address based on Model
  • street property type string
  • city property type string
  • state property type string
  • zipCode property type string

I also want to validate

• contact.emailAddress is unique, but not required
• contact.phoneNumber is unique, but not required

I want know if it's possible validate only when it's present in the payload and using the default validators e.g. validatesUniquenessOf

Currently I've added a validator

//contact-info.js
module.exports = function(ContactInfo) {
  ContactInfo.validatesUniquenessOf('phoneNumber', {message: 'You can\'t use this number', allowNull: true});
};

for testing proposes I have in my database a document in the Customer collection

{
  "_id": ObjectId("56003b7901caa9db416eca5f"),
  "contact": {
    "firstName" "Bob",
    "lastName" "SquarePants",
    "phoneNumber": "555-5678"
  }
}

and sent following request

POST /api/Customers
{
  "contact": {
    "firstName" "Patrick",
    "lastName" "Star",
    "phoneNumber": "555-5678"
  }
}

the expected result is a 422 response but I get a 200, btw I think it should be a 201

I don't believe we support deep validation. See #300 (comment)

Has this been implemented in latest versions ? if not, are there are any future plans to implement this? Happy to pick this up if this is still an open feature
