Loopback 3: Multiple HasOne relation on one model - loopback

Question

So, I opened an issue here, coz in my opinion it should work as I think... but might be wrong so looking for another way
So, pretty much I have two models, Wedding and Person. The Wedding one has these relations set:
"people": {
"type": "hasMany",
"model": "person",
"foreignKey": "",
"options": {
"nestRemoting": true
}
},
"partner1": {
"type": "hasOne",
"model": "person",
"foreignKey": ""
},
"partner2": {
"type": "hasOne",
"model": "person",
"foreignKey": ""
}
And one of my wedding documents looks like this (I am using mongoDB if you cannot tell):
{
"_id": "5de78c76f89d1a8ad4091ca5",
"date": "2019-12-04T10:37:42.000Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"created": "2019-12-04T10:37:42.720Z",
"partner1Id": "5de78c77f89d1a8ad4091ca6",
"partner2Id": "5de78c77f89d1a8ad4091ca7"
}
So, when I set include filter and do:
{ "include": ["partner1", "partner2"]}
in my loopback API explorer on
http://localhost:3000/api/weddings/5de78c76f89d1a8ad4091ca5
I get:
{
"date": "2019-12-04T10:37:42.000Z",
"id": "5de78c76f89d1a8ad4091ca5",
"userId": "5de78c76f89d1a8ad4091ca4",
"created": "2019-12-04T10:37:42.720Z",
"partner1Id": "5de78c77f89d1a8ad4091ca6",
"partner2Id": "5de78c77f89d1a8ad4091ca7",
"partner1": {
"id": "5de78c77f89d1a8ad4091ca7",
"fullName": "Jessica Alba",
"spouse": "spouse2",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
},
"partner2": {
"id": "5de78c77f89d1a8ad4091ca7",
"fullName": "Jessica Alba",
"spouse": "spouse2",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
}
}
But, I am expecting this:
{
"date": "2019-12-04T10:37:42.000Z",
"id": "5de78c76f89d1a8ad4091ca5",
"userId": "5de78c76f89d1a8ad4091ca4",
"created": "2019-12-04T10:37:42.720Z",
"partner1Id": "5de78c77f89d1a8ad4091ca6",
"partner2Id": "5de78c77f89d1a8ad4091ca7",
"partner1": {
"id": "5de78c77f89d1a8ad4091ca6",
"fullName": "Michael Knight",
"spouse": "spouse1",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
},
"partner2": {
"id": "5de78c77f89d1a8ad4091ca7",
"fullName": "Jessica Alba",
"spouse": "spouse2",
"contacts": [],
"verified": false,
"created": "2019-12-04T10:37:43.292Z",
"updated": "2019-12-04T10:37:43.292Z",
"userId": "5de78c76f89d1a8ad4091ca4",
"weddingId": "5de78c76f89d1a8ad4091ca5"
}
}
Any ideas as of why? why do I get the same two records for partner1 and partner2?

Answer 1

Instead of using "hasOne", use "belongsTo".
