# 请求体 - 更新数据 { #body-updates }

## 用 `PUT` 替换式更新 { #update-replacing-with-put }

更新数据可以使用 [HTTP `PUT`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT) 操作。

把输入数据转换为以 JSON 格式存储的数据（比如，使用 NoSQL 数据库时），可以使用 `jsonable_encoder`。例如，把 `datetime` 转换为 `str`。

{* ../../docs_src/body_updates/tutorial001_py310.py hl[28:33] *}

`PUT` 用于接收替换现有数据的数据。

### 关于替换的警告 { #warning-about-replacing }

用 `PUT` 把数据项 `bar` 更新为以下请求体时：

```Python
{

		Contents: []ItemContent{
			{Name: "name", LanguageCode: "en"},
			{Name: "ar name", LanguageCode: "ar"},
		},
	}
	if err := tx.Create(&item).Error; err != nil {
		t.Fatalf("failed to create items, got error: %v", err)
	}

	// test Replace
	if err := tx.Model(&item).Association("Contents").Unscoped().Replace([]ItemContent{
		{Name: "updated name", LanguageCode: "en"},
		{Name: "ar updated name", LanguageCode: "ar"},

	user := *GetUser("update-many2many", Config{})

	if err := DB.Create(&user).Error; err != nil {
		t.Fatalf("errors happened when create: %v", err)
	}

	user.Languages = []Language{{Code: "zh-CN", Name: "Chinese"}, {Code: "en", Name: "English"}}
	for _, lang := range user.Languages {
		DB.Create(&lang)
	}
	user.Friends = []*User{{Name: "friend-1"}, {Name: "friend-2"}}

	if err := DB.Save(&user).Error; err != nil {
