## Instalação de dependências

Para instalar o `jinja2`, siga o código abaixo:

<div class="termy">

```console
$ pip install jinja2
```

</div>

## Usando `Jinja2Templates`

* Importe `Jinja2Templates`.
* Crie um `templates` que você possa reutilizar posteriormente.

        urlIterator.remove()
      }
    }
```

### Troubleshooting

1. Valid cacheable responses are not being cached

Make sure you are reading responses fully as unless they are read fully, cancelled or stalled Responses will not be cached.

### Overriding normal cache behaviour

## Prerequisites

Install Dex by following [Dex Getting Started Guide](https://dexidp.io/docs/getting-started/)

### Start Dex

```
~ ./bin/dex serve dex.yaml
time="2020-07-12T20:45:50Z" level=info msg="config issuer: http://127.0.0.1:5556/dex"

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

Tətbiqimizi əlçatan etmək üçün bizə <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a> və ya <a href="https://github.com/pgjones/hypercorn" class="external-link" target="_blank">Hypercorn</a> kimi ASGI server lazımdır.

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

/// tip | 提示

如果可以，请尽量使用 `Annotated` 版本。

你还可以创建一个 [自定义异常处理器](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} 用于捕获异常（同时也可以抛出另一个 `HTTPException`）。

## 包含 `yield` 和 `except` 的依赖项

如果你在包含 `yield` 的依赖项中使用 `except` 捕获了一个异常，然后你没有重新抛出该异常（或抛出一个新异常），与在普通的Python代码中相同，FastAPI不会注意到发生了异常。

## Install `SQLModel`

First, make sure you create your [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `sqlmodel`:

<div class="termy">

```console
$ pip install sqlmodel
