## Псевдонимы параметров { #alias-parameters }

Представьте, что вы хотите, чтобы параметр назывался `item-query`.

Например:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Но `item-query` — недопустимое имя переменной в Python.

Ближайший вариант — `item_query`.

Но вам всё равно нужно именно `item-query`...

Stellen Sie sich vor, Sie möchten, dass der Parameter `item-query` ist.

Wie in:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Aber `item-query` ist kein gültiger Name für eine Variable in Python.

Der am ähnlichsten wäre `item_query`.

Aber Sie benötigen dennoch, dass er genau `item-query` ist ...

maven.user.conf         = ${user.home}/.m2
maven.project.conf      = ${session.rootDirectory}/.mvn

# Comma-separated list of files to include.
# Each item may be enclosed in quotes to gracefully include spaces. Items are trimmed before being loaded.
# If the first character of an item is a question mark, the load will silently fail if the file does not exist.
${includes} = ?"${maven.user.conf}/maven-system.properties", \

# user properties at the very beginning of Maven's boot process.

## 템플릿 작성하기

그런 다음 `templates/item.html`에 템플릿을 작성할 수 있습니다. 예를 들면:

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### 템플릿 컨텍스트 값

다음과 같은 HTML에서:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...이는 전달한 "컨텍스트" `dict`에서 가져온 `id`를 표시합니다:

```Python
{"id": id}
```

```JSON hl_lines="22"
{
    "openapi": "3.1.0",
    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {
                "summary": "Read Items",
                "operationId": "read_items_items__get",
                "responses": {
                    "200": {
                        "description": "Successful Response",

                        "description": "Successful Response",

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

### Dockerfile { #dockerfile }

Agora, no mesmo diretório do projeto, crie um arquivo `Dockerfile` com:

```{ .dockerfile .annotate }

		Number2 uint64     `gorm:"default:NULL"`
		Number3 float64    `gorm:"default:NULL"`
		Now     *time.Time `gorm:"default:NULL"`
		Item1Id string
		Item1   *QueryResetItem `gorm:"references:ID"`
		Item2Id string
		Item2   *QueryResetItem `gorm:"references:ID"`
	}

	DB.Migrator().DropTable(&QueryResetNullValue{}, &QueryResetItem{})
	DB.AutoMigrate(&QueryResetNullValue{}, &QueryResetItem{})

                    "message": {
                        "title": "Message",
                        "type": "string"
                    }
                }
            },
            "Item": {
                "title": "Item",
                "required": [
                    "id",
                    "value"
