So, the section with:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...will generate a link to the same URL that would be handled by the *path operation function* `read_item(id=id)`.

For example, with an ID of `42`, this would render:

```html
<a href="/items/42">
```

Ainsi, la section suivante :

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

... générera un lien vers la même URL que celle gérée par la *fonction de chemin d'accès* `read_item(id=id)`.

Par exemple, avec un ID de `42`, cela rendrait :

```html
<a href="/items/42">
```

### 模板 `url_for` 参数 { #template-url-for-arguments }

你还可以在模板内使用 `url_for()`，其参数与*路径操作函数*的参数相同。

所以，该部分:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...将生成一个与处理*路径操作函数* `read_item(id=id)`的 URL 相同的链接

例如。当 ID 为 `42` 时, 会渲染成:

```html
<a href="/items/42">
```

## 模板与静态文件 { #templates-and-static-files }

Таким образом, фрагмент:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...сгенерирует ссылку на тот же URL, который обрабатывается *функцией-обработчиком пути* `read_item(id=id)`.

Например, для ID `42` это отрендерится как:

```html
<a href="/items/42">
```

Dolayısıyla şu bölüm:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...*path operation function* olan `read_item(id=id)` tarafından handle edilecek URL'nin aynısına bir link üretir.

Örneğin ID değeri `42` ise, şu şekilde render edilir:

```html
<a href="/items/42">
```
