## Regular expression ekleyin { #add-regular-expressions }

Parametrenin eşleşmesi gereken bir `pattern` <dfn title="String'ler için arama deseni tanımlayan karakter dizisi">düzenli ifade</dfn> tanımlayabilirsiniz:

{* ../../docs_src/query_params_str_validations/tutorial004_an_py310.py hl[11] *}

Bu özel regular expression pattern’i, gelen parametre değerinin şunları sağladığını kontrol eder:

    public static final String FAIL_FAST = "ff";

    public static final String FAIL_ON_SEVERITY = "fos";

    public static final String FAIL_AT_END = "fae";

    public static final String FAIL_NEVER = "fn";

    public static final String RESUME = "r";

    public static final String RESUME_FROM = "rf";

    public static final String PROJECT_LIST = "pl";

     *
     * @param element the element to add
     * @param occurrences the number of occurrences of the element to add. May be zero, in which
     *     case no change will be made.
     * @return this {@code Builder} object
     * @throws NullPointerException if {@code element} is null
     * @throws IllegalArgumentException if {@code occurrences} is negative, or if this operation

                        // checksum doesn't match. This could be a problem with the server (ibiblio HTTP-200 error
                        // page), so we'll try this up to two times. On the second try, we'll handle it as a bona-fide
                        // error, based on the repository's checksum checking policy.
                        if (firstRun) {
                            logger.warn("*** CHECKSUM FAILED - " + e.getMessage() + " - RETRYING");

     * <p>Then the returned value is {@code groupId:artifactId} when there is a name clash and
     * {@code :artifactId} if there is no conflict.

Here we'll see an example using [SQLModel](https://sqlmodel.tiangolo.com/).

**SQLModel** is built on top of [SQLAlchemy](https://www.sqlalchemy.org/) and Pydantic. It was made by the same author of **FastAPI** to be the perfect match for FastAPI applications that need to use **SQL databases**.
