You can declare multiple path parameters and query parameters at the same time, **FastAPI** knows which is which.

And you don't have to declare them in any specific order.

They will be detected by name:

{* ../../docs_src/query_params/tutorial004_py310.py hl[6,8] *}

## Required query parameters { #required-query-parameters }

{* ../../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
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

因为其中未包含已存储的属性 `"tax": 20.2`，输入模型会取 `"tax": 10.5` 的默认值。

因此，保存的数据会带有这个“新的” `tax` 值 `10.5`。

## 用 `PATCH` 进行部分更新 { #partial-updates-with-patch }

						relForeignKeys = append(relForeignKeys, ref.ForeignKey.DBName)
					} else if ref.PrimaryValue != "" {
						queryConds = append(queryConds, clause.Eq{
							Column: clause.Column{Table: rel.JoinTable.Table, Name: ref.ForeignKey.DBName},
							Value:  ref.PrimaryValue,
						})
					}
				}

				_, foreignValues := schema.GetIdentityFieldValuesMap(db.Statement.Context, db.Statement.ReflectValue, foreignFields)

Example: Start MinIO server in a 8 drives setup, using MinIO Docker image.

```sh

现在你可以导入并使用客户端代码了。它可能是这样，并且你会发现方法有自动补全：

要发送的载荷也会有自动补全：

<img src="/img/tutorial/generate-clients/image03.png">

/// tip | 提示

请注意 `name` 和 `price` 的自动补全，它们是在 FastAPI 应用中的 `Item` 模型里定义的。

///

你发送的数据如果不符合要求，会在编辑器中显示内联错误：

<img src="/img/tutorial/generate-clients/image04.png">

响应对象同样有自动补全：
