How to properly bind models in golang?

Question

PostgreSQL

Tell me how to handle cookies and save the article with the owner.

PostgreSQL

create table users(
id varchar(64) primary key, username varchar(64) not null,
password VARCHAR(64));
create table article(
id varchar(64) Primary key,
name Varchar(64),
user_id VARCHAR(64) REFERENCES Users(id));

Modelb

type Article struct {
Id string
Name string
User_*User
}

Recording to the database

func CreateArticle(name string, user *User) (int64, error) {
id, _ := uuid.NewV4()
result, _ := db.Exec("INSERT INTO articles VALUES($1, $2, $3)", id, name, user)
rowsAffected, err := result.RowsAffected()
return rowsAffected, nil
}

Article save function

func NewArticle(w http.ResponseWriter, r *http.Request) {
session, _ := store.Get(r, "cookie-name")
name := r.FormValue("name")
owner := session.Values["username"]
// При проверке типа owner показывает стринг выдает юззернейм
user, _ := models.GetUser(owner) Определяется как интерфейс
rowsAffected, err := models.CreateArticle(name, description, images, price, user)
}

User in the database

func GetUser(username string)(*User, error) {
row := db.QueryRow("SELECT * FROM users WHERE username=$1", username)
fmt.Println(row)
user := new(User)
err := row.Scan(&user.Id, &user.Username, &user.Password)
if err != nil {
return nil, err
}
return user, nil
}

Kindly help in this matter and also throw off a couple of code examples or whole works of articles very much appreciated!

Answer 1

If I understand the question correctly then
article := new(Article)
user := new(User)
article.User = append(article.User,user)
