unsupported Scan

こんなエラーが出たら

sql: Scan error on column index x, name "updated_at": unsupported Scan, storing driver.Value type <nil> into type *time.Time

null パッケージを使う

import (
	"gopkg.in/guregu/null.v3"
	"time"
)

type Hoge struct {
	Id             int64 
	Hoge           string
	CreatedAt      time.Time
	UpdatedAt      null.Time
	DeletedAt      null.Time
}

代入は、キャストして

Hoge.UpdatedAt = null.TimeFrom(time.Now())
