O "fluxo" da `senha` é um dos caminhos ("fluxos") definidos no OAuth2, para lidar com a segurança e autenticação.

OAuth2 foi projetado para que o backend ou a API pudesse ser independente do servidor que autentica o usuário.

Mas nesse caso, a mesma aplicação **FastAPI** irá lidar com a API e a autenticação.

Então, vamos rever de um ponto de vista simplificado:

            IllegalArgumentException.class, () -> networkAsMutableNetwork.addEdge(N1, N1, E11));
    assertThat(e).hasMessageThat().contains(ERROR_SELF_LOOP);
  }

  /**
   * This test checks an implementation dependent feature. It tests that the method {@code addEdge}
   * will silently add the missing nodes to the graph, then add the edge connecting them. We are not

                else {
                    out[ j++ ] = ch;
                }
                break;
            case 1:
                /*
                 * Get ASCII hex value and convert to platform dependent
                 * encoding like EBCDIC perhaps
                 */
                b[ 0 ] = (byte) ( Integer.parseInt(str.substring(i, i + 2), 16) & 0xFF );

                .desc("If project list is specified, also build projects required by the list")
                .build());
        options.addOption(Option.builder(ALSO_MAKE_DEPENDENTS)
                .longOpt("also-make-dependents")
                .desc("If project list is specified, also build projects that depend on projects on the list")
                .build());
        options.addOption(Option.builder(LOG_FILE)

* オプショナルのクエリパラメータ`limit`は`int`で、デフォルトは`100`です。

そして、これらの値を含む`dict`を返します。

### `Depends`のインポート

```Python hl_lines="3"
{!../../docs_src/dependencies/tutorial001.py!}
```

### "dependant"での依存関係の宣言

*path operation関数*のパラメータに`Body`や`Query`などを使用するのと同じように、新しいパラメータに`Depends`を使用することができます:

```Python hl_lines="13  18"
{!../../docs_src/dependencies/tutorial001.py!}
```

### Wstrzykiwanie Zależności

FastAPI zawiera niezwykle łatwy w użyciu, ale niezwykle potężny system <abbr title='Po angielsku: Dependency Injection. Znane również jako "components", "resources", "services", "providers"'><strong>Wstrzykiwania Zależności</strong></abbr>.

* Nawet zależności mogą mieć zależności, tworząc hierarchię lub **"graf" zależności**.

	if len(taggedNamespaces) > 0 && !skipConfirmation {

   *   <li>if truncating for display to users, there are other considerations that must be taken

    O SQLModel saberá que algo declarado como `str` será uma coluna SQL do tipo `TEXT` (ou `VARCHAR`, dependendo do banco de dados).

### Criar um Engine
Um `engine` SQLModel (por baixo dos panos, ele é na verdade um `engine` do SQLAlchemy) é o que **mantém as conexões** com o banco de dados.
