How to update fields in db that are not empty string go gorm?

Question

go

Please tell me, I have a function to update the value of those fields in the database that came from the frontend and which are not an empty string

func EditProduct(c *gin.Context) {
  id := c.Params.ByName("id")
  var body ProductReq
  var product models.Product
  if err := c.ShouldBindJSON(&body); err != nil {
    log.Fatal(err.Error())
    return
  }
  database.DB.Where("id = ?", id).First(&product)
  if body.Title != "" {
    product.Title = body.Title
  }
  if body.Type != "" {
    product.Type = body.Type
  }
  if body.Img != "" {
    product.Img = body.Img
  }
  if body.Brand != "" {
    product.Brand = body.Brand
  }
  if body.Price != "" {
    product.Price = body.Price
  }
  database.DB.Save(&product)
}

is there some method for gorm to update exactly what is not an empty string, instead of writing such an if construct?

I have not seen this, but, in principle, if desired, you can do it with the help of reflection.
But you will have to pay for reflection with performance :)
If you need an implementation example, let me know, I'll do it.
