# Separate OpenAPI Schemas for Input and Output or Not { #separate-openapi-schemas-for-input-and-output-or-not }

Since **Pydantic v2** was released, the generated OpenAPI is a bit more exact and **correct** than before. 😎

In fact, in some cases, it will even have **two JSON Schemas** in OpenAPI for the same Pydantic model, for input and output, depending on if they have **default values**.

Let's see how that works and how to change it if you need to do that.

## Guía oficial { #official-guide }

Pydantic tiene una [Guía de migración](https://docs.pydantic.dev/latest/migration/) oficial de v1 a v2.

También incluye qué cambió, cómo las validaciones ahora son más correctas y estrictas, posibles consideraciones, etc.

Puedes leerla para entender mejor qué cambió.

## Tests { #tests }

        assertTrue(result instanceof Object[]);
        Object[] resultArray = (Object[]) result;
        assertEquals(6, resultArray.length);

        // Verify all values are in correct positions
        assertEquals("initial", resultArray[0]);
        assertEquals("item1", resultArray[1]);
        assertEquals("item2", resultArray[2]);
        assertEquals("item3", resultArray[3]);

        // Then
        assertNotNull(address, "Should return address for IP address");
        assertEquals("127.0.0.1", address.getHostAddress(), "Should return correct IP address");
    }

    @Test
    @DisplayName("Should get all addresses by name")
    void testGetAllByName() throws UnknownHostException {
        // When

También puedes declarar parámetros de **body**, **path** y **query**, todos al mismo tiempo.

**FastAPI** reconocerá cada uno de ellos y tomará los datos del lugar correcto.

{* ../../docs_src/body/tutorial004_py310.py hl[16] *}

Los parámetros de la función se reconocerán de la siguiente manera:

		left -= read
		if !bytes.Equal(h.Sum(nil), hashBuf[:n]) {
			return errFileCorrupt
		}
	}
	return nil
}

// bitrotSelfTest performs a self-test to ensure that bitrot
// algorithms compute correct checksums. If any algorithm
// produces an incorrect checksum it fails with a hard error.
//
// bitrotSelfTest tries to catch any issue in the bitrot implementation
// early instead of silently corrupting data.

        assertArrayEquals(newFileId, actualFileId);

        assertEquals(104, bytesWritten); // 40 bytes header + 64 bytes input buffer
    }

    @Test
    @DisplayName("Test setFileInfoClass sets correct info type")
    void testSetFileInfoClassSetsCorrectInfoType() {
        request = new Smb2QueryInfoRequest(mockConfig);

        // Initially set a different info type
        request.setInfoType((byte) 0x05);

어제 제 친구가 이렇게 썼습니다: "If you spell incorrectly correctly, you have spelled it incorrectly". 이에 저는 이렇게 답했습니다: "Correct, but 'incorrectly' is incorrectly not '"incorrectly"'".

LLM은 아마 이것을 잘못 번역할 것입니다. 흥미로운 점은 재번역할 때 고정된 번역을 유지하는지 여부뿐입니다.
