## Ajouter des validations par expressions régulières

On peut définir une <abbr title="Une expression régulière, regex ou regexp est une suite de caractères qui définit un pattern de correspondance pour les chaînes de caractères.">expression régulière</abbr> à laquelle le paramètre doit correspondre :

```Python hl_lines="10"

## Adicionando expressões regulares

Você pode definir uma <abbr title="Uma expressão regular, regex ou regexp é uma sequência de caracteres que define um parâmetro de busca para textos.">expressão regular</abbr> que combine com um padrão esperado pelo parâmetro:

```Python hl_lines="11"

	if !regexp.MustCompile("SELECT .*id.*name.*updated_at.*created_at.* FROM .*users").MatchString(result.Statement.SQL.String()) {
		t.Fatalf("SQL should include selected names, but got %v", result.Statement.SQL.String())
	}

	result = DB.Session(&gorm.Session{DryRun: true}).Model(&User{}).Find(&User{}, user.ID)

	if !regexp.MustCompile("SELECT \\* FROM `user`").MatchString(r.Statement.SQL.String()) {
		t.Errorf("Table with escape character, got %v", r.Statement.SQL.String())

	r = dryDB.Table("user as u").Select("name").Find(&User{}).Statement
	if !regexp.MustCompile("SELECT .name. FROM user as u WHERE .u.\\..deleted_at. IS NULL").MatchString(r.Statement.SQL.String()) {
