Mit diesen Ideen kann JWT für weitaus anspruchsvollere Szenarien verwendet werden.

In diesen Fällen könnten mehrere dieser Entitäten die gleiche ID haben, sagen wir `foo` (ein Benutzer `foo`, ein Auto `foo` und ein Blog-Beitrag `foo`).

Usando estas ideas, JWT puede ser utilizado para escenarios mucho más sofisticados.

En esos casos, varias de esas entidades podrían tener el mismo ID, digamos `foo` (un usuario `foo`, un coche `foo`, y un artículo del blog `foo`).

	DB.AutoMigrate(&CustomizeColumn{})

	expected := "foo"
	now := time.Now()
	cc := CustomizeColumn{ID: 666, Name: expected, Date: &now}

	if count := DB.Create(&cc).RowsAffected; count != 1 {
		t.Error("There should be one record be affected when create record")
	}

	var cc1 CustomizeColumn
	DB.First(&cc1, "mapped_name = ?", "foo")

	if cc1.Name != expected {
		t.Errorf("Failed to query CustomizeColumn")

The defaultValueMap.dataprop is for common columns like this:
/- - - - - - - - - - - - - - - - - - - -
map:{
    ; REGISTER_DATETIME = sysdate
    ; REGISTER_USER     = foo
    ; REGISTER_PROCESS  = bar
    ; UPDATE_DATETIME   = sysdate
    ; UPDATE_USER       = foo
    ; UPDATE_PROCESS    = bar
    ; VERSION_NO        = 0
}

Então, se você rodar este exemplo e for até <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, você verá a seguinte resposta:

```JSON
{"item_id":"foo"}
```

## Parâmetros da rota com tipos

Você pode declarar o tipo de um parâmetro na função usando as anotações padrões do Python:
