gorm插入不支持的数据

我试图使用gorm将一个 struct Named Teacher插入到SQLite数据库中，当我调用创建函数时，我收到一个错误:

INSERT INTO `teachers` (`name`,`department`,`password`) VALUES  RETURNING `id`
panic: unsupported data

这是我的老师 struct :

type Teacher struct {
    Id         int    `json:"id" db:"id" gorm:"primarykey"`
    Name       string `json:"name" db:"name"`
    Department string `json:"department" db:"department"`
    Password   string `json:"-" db:"password"`
}

这就是我插入的方式:

data := Teacher{
        Id:         0,
        Name:       "JohnDoe",
        Department: "ComputerScience",
        Password:   "12312312312321",
    }
DB.Create(&data)

编辑:

一些更多代码用于理解:

Main.go:

t := models.Teacher{
        Id:         0,
        Name:       "JohnDoe",
        Department: "ComputerScience",
        Password:   "12312312312321",
    }
    t.CreateTeacher()

teacher.go:

type Teacher struct {
    Id         int    `json:"id" db:"id" gorm:"primarykey"`
    Name       string `json:"name" db:"name"`
    Department string `json:"department" db:"department"`
    Password   string `json:"-" db:"password"`
}

func (teacher Teacher) CreateTeacher() error {
    fmt.Println(teacher)
    err := database.Insert(teacher)
    if err != nil {
        panic(err)
    }
    return nil
}

数据库.Go:

func ConnectDatabase() error {
    var err error
    DB, err = gorm.Open(sqlite.Open("./cisl-database.db"), &gorm.Config{})
    if err != nil {
        return err
    }
    return nil
}
func Insert(data interface{}) error {
    fmt.Print(data)
    err := ConnectDatabase()
    if err != nil {
        return err
    }

    DB.AutoMigrate(&data)
    
    if err := DB.Create(&data).Error; err != nil {
        return err
    }
    return nil
}
