## Birden Fazla Model ile Uygulamayı Güncelleme { #update-the-app-with-multiple-models }

Şimdi bu uygulamayı biraz **refactor** edelim ve **güvenliği** ile **esnekliği** artıralım.

Önceki uygulamaya bakarsanız, UI’da şu ana kadar client’ın oluşturulacak `Hero`’nun `id` değerini belirlemesine izin verdiğini görebilirsiniz. 😱

        writeInt8(1000, buffer, 8); // free allocation units
        writeInt4(8, buffer, 16); // sectors per allocation unit
        writeInt4(4096, buffer, 20); // bytes per sector

        int bytesRead = response.readDataWireFormat(buffer, 0, buffer.length);

        assertEquals(24, bytesRead, "Should read 24 bytes");
        assertNotNull(response.info, "Info object should not be null");

	})
}

func TestSelfReferentialBelongsTo(t *testing.T) {
	type User struct {
		ID        int32 `gorm:"primaryKey"`
		Name      string
		CreatorID *int32
		Creator   *User
	}

	checkStructRelation(t, &User{}, Relation{
		Name: "Creator", Type: schema.BelongsTo, Schema: "User", FieldSchema: "User",
		References: []Reference{{"ID", "User", "CreatorID", "User", "", false}},
	})
}

Ici, avec `ge=1`, `item_id` devra être un nombre entier « `g`reater than or `e`qual » à `1`.

## Validations numériques : supérieur et inférieur ou égal { #number-validations-greater-than-and-less-than-or-equal }

La même chose s'applique pour :

* `gt` : `g`reater `t`han
* `le` : `l`ess than or `e`qual

Aqui, com `ge=1`, `item_id` precisará ser um número inteiro “`g`reater than or `e`qual” a `1`.

## Validações numéricas: maior que e menor que ou igual { #number-validations-greater-than-and-less-than-or-equal }

O mesmo se aplica a:

* `gt`: maior que (`g`reater `t`han)
* `le`: menor que ou igual (`l`ess than or `e`qual)

使用 `Query` 和 `Path`（以及你之後會看到的其他類別）可以宣告數值限制。

這裡用 `ge=1`，代表 `item_id` 必須是「大於（`g`reater）或等於（`e`qual）」`1` 的整數。

{* ../../docs_src/path_params_numeric_validations/tutorial004_an_py310.py hl[10] *}

## 數值驗證：大於與小於或等於 { #number-validations-greater-than-and-less-than-or-equal }

同樣也適用於：

* `gt`：大於（`g`reater `t`han）
* `le`：小於或等於（`l`ess than or `e`qual）
