Unmarshal of object/struct attributes fails

[gopherfortress]

Hello,

I am trying to unmarshal a JSON API response which contains attributes that are objects. I tried marshaling and the result JSON is correct but when I try to unmarshal that same JSON it fails with data is not a jsonapi representation of '*main.Profile'. Here is some example code:

package main

import (
	"bytes"
	"fmt"
	"log"

	"github.com/google/jsonapi"
)

func main() {
	p := &Profile{ID: "1", Avatar: &Avatar{Large: "url1", Small: "url2"}}
	buf := &bytes.Buffer{}
	if err := jsonapi.MarshalOnePayload(buf, p); err != nil {
		log.Fatal(err)
	}

	p = &Profile{}
	fmt.Println(string(buf.Bytes()))
	err := jsonapi.UnmarshalPayload(buf, p)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("ID: %v, Avatar:%v\n", p.ID, p.Avatar)
}

type Profile struct {
	ID     string  `json:"id" jsonapi:"primary,profiles"`
	Avatar *Avatar `json:"avatar" jsonapi:"attr,avatar"`
}

type Avatar struct {
	Large string `json:"large"`
	Small string `json:"small"`
}

I also tried annotating with attr like

type Avatar struct {
	Large string `json:"large" jsonapi:"attr,large,omitempty"`
	Small string `json:"small" jsonapi:"attr,small,omitempty"`
}

but no luck.

Any news about this issue? Thanks.

We have been actively working on this feature in the branch https://github.com/google/jsonapi/tree/feature/embeded-structs

Is work on this still progressing? My case is similar but here is my code:

type Profile struct {
ID string json:"id" jsonapi:"primary,profiles"
AvatarList []Avatar json:"avatar" jsonapi:"attr,avatar"
}

type Avatar struct {
Large string json:"large"
Small string json:"small"
}

I tried this with the current embeded-structs branch and it didn't work. Any status on this would be appreciated. The marshal function returned what I expected but the unmarshal returned an error ("data is not a jsonapi representation of '*jsonapi.Profile").

same issue here. Can't unmarshal the json to the struct with attributes that a objects.... Can't even find any workaround.

any update on this issue?

It seems we can't use arrays of simple types inside attributes either: https://go.dev/play/p/3qufy0gFk3u
