read_items - Code Search

docs/ru/docs/advanced/templates.md

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">
```

```html
Item ID: 42
```

### 模板 `url_for` 参数

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">
```

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">
```
