### Використання параметра `update` у Pydantic

Тепер Ви можете створити копію наявної моделі за допомогою `.model_copy()`, і передати параметр `update` з `dict` , який містить дані для оновлення.

			if dc.IsNil() {
				err = dc.ReadNil()
				if err != nil {
					err = msgp.WrapError(err, "Update")
					return
				}
				z.Update = nil
			} else {
				if z.Update == nil {
					z.Update = new(dataUsageEntry)
				}
				err = z.Update.DecodeMsg(dc)
				if err != nil {
					err = msgp.WrapError(err, "Update")
					return
				}
			}
		case "f":
			if dc.IsNil() {
				err = dc.ReadNil()

    }

    /**
     * Deletes a related query from the database.
     * After deletion, the related query helper is updated to refresh the cache.

	if err := DB.Model(&data).Update("password", EncryptedData("xnewpass")).Error; err == nil {
		t.Errorf("Should failed to update data with invalid data")
	}

	if err := DB.Model(&data).Update("password", EncryptedData("newpass")).Error; err != nil {
		t.Errorf("Should got no error update data with valid data, but got %v", err)
	}

Note, since it is still `pip` and `pip-compile` tools used under the hood, so
most of the command line arguments and features supported by those tools will be
acknowledged by the Bazel requirements updater command as well. For example, if
you wish the updater to consider pre-release versions simply pass `--pre`
argument to the bazel command:

### Usando o parâmetro `update` do Pydantic

Agora, você pode criar uma cópia do modelo existente usando `.model_copy()`, e passar o parâmetro `update` com um `dict` contendo os dados para atualizar.

/// info | Informação

		t.Fatalf("failed to query data, got error %v", err)
	}

	AssertEqual(t, result, data)

	if err := DB.Model(&result).Update("roles", "").Error; err != nil {
		t.Fatalf("failed to update data's roles, got error %v", err)
	}

	if err := DB.First(&result, data.ID).Error; err != nil {
		t.Fatalf("failed to query data, got error %v", err)
	}
}

		},
		{
			[]clause.Interface{
				clause.Update{},
				clause.Set([]clause.Assignment{{clause.PrimaryColumn, 1}}),
				clause.Set([]clause.Assignment{{clause.Column{Name: "name"}, "jinzhu"}}),
