Gorp Transient

テーブルに無いフィールド使いたい　（矛盾）　modelに入れたい

type ColumnMap

https://godoc.org/github.com/coopernurse/gorp

type ColumnMap struct {
    // Column name in db table
    ColumnName string

    // If true, this column is skipped in generated SQL statements
    Transient bool

    // If true, " unique" is added to create table statements.
    // Not used elsewhere
    Unique bool

    // Passed to Dialect.ToSqlType() to assist in informing the
    // correct column type to map to in CreateTables()
    // Not used elsewhere
    MaxSize int
    // contains filtered or unexported fields
}

使い方

gorp.go

	t := Dbm.AddTable(models.User{}).SetKeys(true, "UserId")
	t.ColMap("Password").Transient = true
	setColumnSizes(t, map[string]int{
		"Username": 20,
		"Name":     100,
	})

勉強なります。
