**FastAPI**, tüm esnekliği korurken uygulamanızı yapılandırmanıza yardımcı olan pratik bir araç sunar.

/// info | Bilgi

Flask'ten geliyorsanız, bu yapı Flask'in Blueprints'ine denk gelir.

## Örnek Bir Dosya Yapısı { #an-example-file-structure }

Diyelim ki şöyle bir dosya yapınız var:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py

在這個例子中可能不是問題，因為是同一個使用者送出該密碼。

但如果我們對其他「路徑操作」使用相同的模型，我們可能會把使用者密碼送給所有用戶端。

/// danger | 警告

除非你非常清楚所有影響並確定自己在做什麼，否則永遠不要儲存使用者的明文密碼，也不要像這樣在回應中傳送。

///

## 新增一個輸出模型 { #add-an-output-model }

我們可以改為建立一個包含明文密碼的輸入模型，以及一個不含密碼的輸出模型：

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

在這裡，雖然「路徑操作函式」回傳的是同一個包含密碼的輸入使用者：

* `Field(index=True)` 会告诉 SQLModel 应该为此列创建一个 **SQL 索引**，这样在读取按此列过滤的数据时，程序能在数据库中进行更快的查找。

    SQLModel 会知道声明为 `str` 的内容将是类型为 `TEXT`（或 `VARCHAR`，具体取决于数据库）的 SQL 列。

### 创建引擎（Engine） { #create-an-engine }

SQLModel 的 `engine`（实际上它是一个 SQLAlchemy 的 `engine`）是用来与数据库**保持连接**的。

你只需构建**一个 `engine` 对象**，让你的所有代码连接到同一个数据库。

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

	"os"
	"path"
	"path/filepath"
	"reflect"
	"slices"
	"strings"
	"testing"
	"time"
)

type testError struct{ error }

type fileOps []any // []T where T is (string | int64)

// testFile is an io.ReadWriteSeeker where the IO operations performed
// on it must match the list of operations in ops.
type testFile struct {
	ops fileOps
	pos int64
}

func (f *testFile) Read(b []byte) (int, error) {

向客户端返回 HTTP 错误响应，可以使用 `HTTPException`。

### 导入 `HTTPException` { #import-httpexception }

{* ../../docs_src/handling_errors/tutorial001_py310.py hl[1] *}

### 在代码中触发 `HTTPException` { #raise-an-httpexception-in-your-code }

`HTTPException` 是额外包含了和 API 有关数据的常规 Python 异常。

因为是 Python 异常，所以不能 `return`，只能 `raise`。
