Gorm setting default value for a field is not working

Your Question

My question is that why when I create a new object why default values aren't used in object creation?

// Todo model
type Todo struct {
    ID        uint      `gorm:"primarykey" json:"id"`
    Title     string    `gorm:"size:100" json:"title"`
    Status    string    `gorm:"size:20,default:Created,index" json:"status"`
    CreatedAt time.Time `gorm:"autoCreateTime" json:"createdAt"`
    UpdatedAt time.Time `gorm:"autoUpdateTime" json:"updatedAt"`
}

// Here is the create query
todo := db.Todo{Title: "Some title"}
result := m.App.DB.Create(&todo)

fmt.Println(todo.Status)
// Output:
// nothing (empty string)

I have also tried below query but I still get the same results:

m.App.DB.Select("Title").Create(&todo)

Expected answer

Set default value for structs before creating.

fmt.Println(todo.Status)
// Output:
// Created

same as this issue https://github.com/go-gorm/gorm/issues/5146 if you need the defeault values , define mode like this

// Todo model
type Todo struct {
    ID        *uint      `gorm:"primarykey" json:"id"`
    Title     *string    `gorm:"size:100" json:"title"`
    Status    *string    `gorm:"size:20,default:Created,index" json:"status"`
    CreatedAt *time.Time `gorm:"autoCreateTime" json:"createdAt"`
    UpdatedAt *time.Time `gorm:"autoUpdateTime" json:"updatedAt"`
}

The tag separator is ; not ,

type Todo struct {
    ...
    Status    string    `gorm:"size:20;default:Created;index" json:"status"`
}

I don't think it's the problem. look at this model in the docs:

type User struct {
  ID   int64
  Name string `gorm:"default:galeone"`
  Age  int64  `gorm:"default:18"`
}

Thanks, tag separator was the problem. @a631807682
