## Depreciar uma *operação de rota*

Se você precisar marcar uma *operação de rota* como <abbr title="obsoleta, recomendada não usá-la">descontinuada</abbr>, mas sem removê-la, passe o parâmetro `deprecated`:

```Python hl_lines="16"

	Query       *DB    // required subquery.
}

// ColumnType column type interface
type ColumnType interface {
	Name() string
	DatabaseTypeName() string                 // varchar
	ColumnType() (columnType string, ok bool) // varchar(64)
	PrimaryKey() (isPrimaryKey bool, ok bool)
	AutoIncrement() (isAutoIncrement bool, ok bool)
	Length() (length int64, ok bool)
	DecimalSize() (precision int64, scale int64, ok bool)

// are not included.
// Common type names include "VARCHAR", "TEXT", "NVARCHAR", "DECIMAL", "BOOL",
// "INT", and "BIGINT".
func (ct ColumnType) DatabaseTypeName() string {
	if ct.DataTypeValue.Valid {
		return ct.DataTypeValue.String
	}
	return ct.SQLColumnType.DatabaseTypeName()
}

// ColumnType returns the database type of the column. like `varchar(16)`
func (ct ColumnType) ColumnType() (columnType string, ok bool) {

	AssertEqual(t, err, nil)
}

func TestBelongsToAssociationUnscoped(t *testing.T) {
	type ItemParent struct {
		gorm.Model
		Logo string `gorm:"not null;type:varchar(50)"`
	}
	type ItemChild struct {
		gorm.Model
		Name         string `gorm:"type:varchar(50)"`
		ItemParentID uint
		ItemParent   ItemParent
	}

	tx := DB.Session(&gorm.Session{})
	tx.Migrator().DropTable(&ItemParent{}, &ItemChild{})

	type ItemContent struct {
		gorm.Model
		ItemID       uint   `gorm:"not null"`
		Name         string `gorm:"not null;type:varchar(50)"`
		LanguageCode string `gorm:"not null;type:varchar(2)"`
	}
	type Item struct {
		gorm.Model
		Logo     string        `gorm:"not null;type:varchar(50)"`
		Contents []ItemContent `gorm:"foreignKey:ItemID"`
	}

	tx := DB.Session(&gorm.Session{})

Öyle ya da böyle zıt uçlarda olmalarına rağmen birbirlerini tamamlıyorlar.

## Gereksinimler

Çeşitli alternatifleri test ettikten sonra, avantajlarından dolayı <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">**Pydantic**</a>'i kullanmaya karar verdim.

	if err != nil {
		t.Errorf("take err:%v", err)
	}
}

func TestDifferentTypeWithoutDeclaredLength(t *testing.T) {
	type DiffType struct {
		ID   uint
		Name string `gorm:"type:varchar(20)"`
	}

	type DiffType1 struct {
		ID   uint
		Name string `gorm:"type:text"`
	}

	var err error
	DB.Migrator().DropTable(&DiffType{})

	err = DB.AutoMigrate(&DiffType{})

const (

	psqlCreateNamespaceTable = `CREATE TABLE %s (key VARCHAR PRIMARY KEY, value JSONB);`
	psqlCreateAccessTable    = `CREATE TABLE %s (event_time TIMESTAMP WITH TIME ZONE NOT NULL, event_data JSONB);`
