style V2 fill:#f9fff3
    style V1 fill:#fff6f0
    style V1Field fill:#fff6f0
    style V2Field fill:#f9fff3
```

In some cases, it's even possible to have both Pydantic v1 and v2 models in the same **path operation** in your FastAPI app:

{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

o que seria equivalente a:

```python
from backend.main import app
```

### `fastapi dev` com caminho { #fastapi-dev-with-path }

Você também pode passar o caminho do arquivo para o comando `fastapi dev`, e ele deduzirá o objeto da aplicação FastAPI a usar:

```console
$ fastapi dev main.py
```

	if b == nil {
		logger.Info("bucketMetacache.findCache: nil cache for bucket %s", o.Bucket)
		return metacache{}
	}

	if o.Bucket != b.bucket {
		logger.Info("bucketMetacache.findCache: bucket %s does not match this bucket %s", o.Bucket, b.bucket)
		debug.PrintStack()
		return metacache{}
	}

	// Grab a write lock, since we create one if we cannot find one.
	b.mu.Lock()
	defer b.mu.Unlock()

        assertTrue(result.contains("secretkey={cipher}"));
        assertFalse(result.contains("secretkey=unencrypted"));

        // Test with keys that don't match pattern
        value = "normalfield=value\npassword=secret";
        result = ParameterUtil.encrypt(value);
        assertTrue("Result should contain normalfield=value, but was: " + result, result.contains("normalfield=value"));

        problems.setSource("");

        userSettings = interpolate(userSettings, request, problems);

        // for the special case of a drive-relative Windows path, make sure it's absolute to save plugins from trouble
        String localRepository = userSettings.getLocalRepository();
        if (localRepository != null && !localRepository.isEmpty()) {

# 응답을 직접 반환하기 { #return-a-response-directly }

**FastAPI**에서 *경로 처리(path operation)*를 생성할 때, 일반적으로 `dict`, `list`, Pydantic 모델, 데이터베이스 모델 등의 데이터를 반환할 수 있습니다.

[응답 모델](../tutorial/response-model.md)을 선언하면 FastAPI는 Pydantic을 사용해 데이터를 JSON으로 직렬화합니다.

응답 모델을 선언하지 않으면, FastAPI는 [JSON 호환 가능 인코더](../tutorial/encoder.md)에 설명된 `jsonable_encoder`를 사용해 데이터를 변환하고 이를 `JSONResponse`에 넣습니다.

또한 `JSONResponse`를 직접 생성해 반환할 수도 있습니다.

    style V2 fill:#f9fff3
    style V1 fill:#fff6f0
    style V1Field fill:#fff6f0
    style V2Field fill:#f9fff3
```

En algunos casos, incluso es posible tener modelos de Pydantic v1 y v2 en la misma **path operation** de tu app de FastAPI:

{* ../../docs_src/pydantic_v1_in_v2/tutorial003_an_py310.py hl[2:3,6,12,21:22] *}

如果你声明了返回类型，FastAPI 会用它来验证数据、在 OpenAPI 中生成文档、进行过滤，并使用 Pydantic 进行序列化。

/// tip | 提示

由于 Pydantic 会在 Rust 侧进行序列化，如果你声明了返回类型，将获得更高的性能。

### 非异步的*路径操作函数* { #non-async-path-operation-functions }

你也可以使用常规的 `def` 函数（不带 `async`），并以同样的方式使用 `yield`。

FastAPI 会确保其正确运行，不会阻塞事件循环。

因为这个函数不是异步的，合适的返回类型是 `Iterable[Item]`：

    }

    @Test
    @DisplayName("Test log file access")
    void testLogFileAccess() {
        logger.logFileAccess("READ", "/path/to/file.txt", true, "testuser");

        Map<EventType, Long> stats = logger.getStatistics();
        assertEquals(Long.valueOf(1), stats.get(EventType.FILE_ACCESS), "Should have 1 file access event");
    }

    @Test

                            Severity.ERROR,
                            "pluginGroups.pluginGroup[" + i + "]",
                            null,
                            "must denote a valid group id and match the pattern " + ID);
                }
            }
        }

        List<Server> servers = settings.getServers();

        if (servers != null) {
            Set<String> serverIds = new HashSet<>();
