Footprint and populate models are not working as expected

[KNTH01]

Hi,

I am not sure if this is a bug, or if this works as designed.

I use trailpack-waterline for my ORM and mongodb.

Here is my footprints.js :

  models: {
    options: {
      /**
       * Whether to populate all model associations by default (for "find")
       */
      populate: true
    },

Then, when I perform a GET request :

GET /user HTTP/1.1
Host: localhost:3000
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: c2680799-ac9a-b0ef-be1d-2a9222303881

{
    "address": "5754340ddd1aa8442a6df9e9",
    "email": "admin@admin.com",
    "firstName": "Kevin",
    "lastName": "Nguyen",
    "createdAt": "2016-05-29T14:01:02.953Z",
    "updatedAt": "2016-06-05T14:15:41.832Z",
    "id": "574af61e0d08d6a23108467f"
  },

The address attribute is not populated as I expect. I have to make this request to have my attribute populated :

GET /user?populate=address HTTP/1.1
Host: localhost:3000
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 405fcb38-41f4-ae1c-f9ed-f223f14ea46c

  {
    "address": {
      "streetAddress": "1360 route des Dolines",
      "zipCode": "06560",
      "city": "Sophia-Antipolis",
      "createdAt": "2016-06-05T14:15:41.822Z",
      "updatedAt": "2016-06-05T14:15:41.822Z",
      "id": "5754340ddd1aa8442a6df9e9"
    },
    "email": "admin@admin.com",
    "firstName": "Kevin",
    "lastName": "Nguyen",
    "createdAt": "2016-05-29T14:01:02.953Z",
    "updatedAt": "2016-06-05T14:15:41.832Z",
    "id": "574af61e0d08d6a23108467f"
  },

So the question is : What if I have many attributes I want to populate in the GET request ?

I also have another question :

In my client, I want to perform an update on a user, and this is working, although I am surprised :

this.$http({
      url: `/user/${user.id}`,
      method: 'PUT',
      data: {
        firstName: user.firstName,
        lastName: user.lastName,
        address: {
          streetAddress: user.address.streetAddress,
          zipCode: user.address.zipCode,
          city: user.address.city
        }
      }
    })

Trails response on a PUT request gives me a user but the address attribute is still not populated. BTW, the address field is well updated.

Thanks for explaining me how this works! :)
