For example, as in the `Image` model we have a `url` field, we can declare it to be an instance of Pydantic's `HttpUrl` instead of a `str`:

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

The string will be checked to be a valid URL, and documented in JSON Schema / OpenAPI as such.

This is a link to one of the pages on FastAPI site: [How to](https://fastapi.tiangolo.com/how-to/) - tool should add language code to the URL.

Link to test wrong attribute: [**FastAPI** Project Generators](project-generation.md){.internal-link} - tool should fix the attribute.

Link with a title: [Example](https://example.com "Example site") - URL will be fixed, title preserved.
