Support for Array of Array of Json Object in model properties

[PRAKASH-SIVAGURUNATHAN]

We have a model as shown below

{
  "name": "accounts",
  "plural": "accounts",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "name": {
      "type": "string"
    },
    "items": {
      "type" : [
        [
          {"itemname": {"type": "string"}}
        ]
      ]
    }
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}

Loopback explorer show the below structure

but during runtime operations the response of the items is not coming as array of array of json object as shown below

@hacksparrow, the PR has landed. Is this issue good to close? Thanks.

[dhmlau]

The fix is in loopback-datasource-juggler@4.6.0.

[hacksparrow]

This one's not fixed. This is the List breaker.

[dhmlau]

@PRAKASH-SIVAGURUNATHAN, @hacksparrow has fixed it in master and 3.x. Closing this issue as resolved. Thanks.

@dhmlau @hacksparrow Can we get this fix in version 2.x. cc: @bajtos

[dhmlau]

@snarjuna , we had a very brief chat with @PRAKASH-SIVAGURUNATHAN and indicated that the codebase is a bit different in 2.x than in 3.x/master. @hacksparrow did some investigation and it would be a huge effort to have it fixed in 2.x as well. If your team is planning to move to a recent version in 2 months or so (there had been some conversation about that with @RobPhippen as well), it may not worth the effort to do so.

[bajtos]

it may not worth the effort to do so.

+1

Especially considering that LoopBack 2.x is going end of life in about two weeks (at the end of April 2019), see https://github.com/strongloop/loopback#module-long-term-support-policy.

@dhmlau @bajtos Thanks for details. I will check with team and come back.
