Але тепер Ви знаєте, що коли вони знадобляться, їх можна застосовувати у **FastAPI**.

### Pydantic v1 `regex` замість `pattern`

До версії Pydantic 2 і FastAPI 0.100.0 параметр називався `regex` замість `pattern`, але тепер він застарів.

Ви все ще можете зустріти код, який використовує його:

//// tab | Pydantic v1

    assertThat(ArbitraryInstances.get(GenericDeclaration.class)).isNotNull();
  }

  public void testGet_regex() {
    assertEquals(Pattern.compile("").pattern(), ArbitraryInstances.get(Pattern.class).pattern());
    assertEquals(0, ArbitraryInstances.get(MatchResult.class).groupCount());
  }

  public void testGet_usePublicConstant() {

    void testDecodeDataIntegrity() throws SMBProtocolDecodingException {
        // Prepare buffer with specific pattern
        byte[] buffer = new byte[32];
        byte[] expectedData = new byte[16];

        // Fill data section with pattern
        for (int i = 0; i < 16; i++) {
            expectedData[i] = (byte) (0xA0 + i);
            buffer[16 + i] = expectedData[i];
        }

Ahora sabes que cuando las necesites puedes usarlas en **FastAPI**.

### Pydantic v1 `regex` en lugar de `pattern` { #pydantic-v1-regex-instead-of-pattern }

Antes de la versión 2 de Pydantic y antes de FastAPI 0.100.0, el parámetro se llamaba `regex` en lugar de `pattern`, pero ahora está en desuso.

Todavía podrías ver algo de código que lo usa:
