Окрім звичайних типів, таких як `str`, `int`, `float`, та ін. Ви можете використовувати складніші типи, які наслідують `str`.

Щоб побачити всі доступні варіанти, ознайомтеся з оглядом <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">типів у Pydantic</a>. Деякі приклади будуть у наступних розділах.

Наприклад, у моделі `Image` є поле `url`, тому ми можемо оголосити його як `HttpUrl` від Pydantic замість `str`:

        if (factory != null) {
            return factory.create(url, rootPackage, rootDir);
        }
        logger.log("WCL0013", asArray(rootPackage, url));
        return null;
    }

    /**
     * Converts a package name to a directory name and returns it.
     *
     * @param packageName
     *            The package name.
     * @return The directory name.

* Convert the copied model to something that can be stored in your DB (for example, using the `jsonable_encoder`).
    * This is comparable to using the model's `.model_dump()` method again, but it makes sure (and converts) the values to data types that can be converted to JSON, for example, `datetime` to `str`.
* Save the data to your DB.
* Return the updated model.
