How to Eager Loading belongs to relationship using GORM

I have these two structs:

// `User` belongs to `Company`, `CompanyID` is the foreign key
type User struct {
  gorm.Model
  Name      string
  CompanyID int
  Company   Company
}

type Company struct {
  ID   int
  Name string
}

If I want to query User with Company data included in it, I can do this:

user := new(User)
db.Preload("Company").Find(user)

But I want to query Company and include User in it, If I do this

company := new(Company)
db.Preload("User").Find(company)

It will throw an error like:

> "User: unsupported relations for schema Company"

That's understandable, because there is no field User in Company struct.

if I add User field like this:

type Company struct {
      ID   int
      Name string
      User User
}

it throws error like:

> "illegal cycle in declaration of User"

As suggested in the comments by @kaushik, a working solution could be:

package main

import (
	"fmt"

	"gorm.io/driver/postgres"
	"gorm.io/gorm"
)

type User struct {
	gorm.Model
	Name      string
	CompanyID int
	Company   Company
}

type Company struct {
	ID   int
	Name string
	User *User
}

func main() {
	dsn := "host=localhost port=54322 user=postgres password=postgres dbname=postgres sslmode=disable"
	db, err := gorm.Open(postgres.Open(dsn))
	if err != nil {
		panic(err)
	}

	db.AutoMigrate(&Company{})
	db.AutoMigrate(&User{})
	// db.Create(&Company{ID: 1, Name: "ACME", User: &User{Name: "John"}})
	// db.Create(&User{Model: gorm.Model{ID: 2}, Name: "Suzy", Company: Company{ID: 2, Name: "XYZ"}})
	var company Company
	if err := db.Debug().Model(&Company{}).Preload("User").Find(&company).Error; err != nil {
		panic(err)
	}
	fmt.Println("User:", company.User.Name)
}

Let me know if this helps you, thanks!
