Gorm: can you change the gorm.Model definition？

gorm.Model

now:

type Model struct {
  ID        uint `gorm:"primary_key"`
  CreatedAt time.Time
  UpdatedAt time.Time
  DeletedAt *time.Time
}

new:

type Model struct {
    ID        uint       `gorm:"primary_key" json:"id"`
    CreatedAt time.Time  `json:"created_at"`
    UpdatedAt time.Time  `json:"updated_at"`
    DeletedAt *time.Time `json:"deleted_at"`
}

You don't have to use gorm.Model in your structs. gorm.Model isn't required and doesn't do anything apart from providing these fields. Instead, GORM looks for fields with the names "ID", "CreatedAt", and so on and updates them accordingly (relevant documentation).

This means that you can define your own "base model" struct:

type MyModel struct {
  ID        uint       `gorm:"primary_key" json:"id"`
  CreatedAt time.Time  `json:"created_at"`
  UpdatedAt time.Time  `json:"updated_at"`
  DeletedAt *time.Time `json:"deleted_at"`
}

and use it in your structs:

type User struct {
  MyModel

  Name string `json:"name"`
}

The fields from MyModel will be treated the same way as those defined in gorm.Model.
