Gorm Field Overwriting Issue with Embedded Structs in GORM

GORM Playground Link

https://github.com/go-gorm/playground/pull/1

Description

When using GORM to map structs to a database, an issue arises when embedding structs that have fields with the same name as those in the outer struct. Specifically, when embedding an Author struct within a Food struct, if both structs contain a field named Name, only the outer struct's field (Food.Name) is saved to the database, while the embedded struct's field (Author.Name) is ignored.

Example Code:

```go package main

import ( "gorm.io/driver/sqlite" "gorm.io/gorm" "log" )

type Author struct { gorm.Model Name string json:"name" gorm:"not null" Email string json:"email" gorm:"not null" }

type Food struct { gorm.Model Name string json:"name" gorm:"not null" Price string json:"price" gorm:"not null" Calories string json:"calories" Proteins string json:"proteins" Fats string json:"fats" Carbohydrates string json:"carbohydrates" Sodium string json:"sodium" Author Author json:"author" gorm:"embedded" }

func main() { db, err := gorm.Open(sqlite.Open("food.db"), &gorm.Config{}) if err != nil { log.Fatalf("failed to connect to the database: %v", err) }

// Auto-migrate the Food and Author structs to create the necessary tables
if err := db.AutoMigrate(&Food{}); err != nil {
    log.Fatalf("failed to migrate: %v", err)
}

// Create a new Food item with an embedded Author
food := Food{
    Name: "Pasta",
    Author: Author{
        Name:      "Chef Mario",
        Biography: "A renowned chef known for Italian cuisine.",
    },
}

// Save the food item to the database
if err := db.Create(&food).Error; err != nil {
    log.Fatalf("failed to create food item: %v", err)
}

log.Println("Food item created successfully!")

}
