### Pydantic v1 `regex` en lugar de `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:

The `Hero` class is very similar to a Pydantic model (in fact, underneath, it actually *is a Pydantic model*).

There are a few differences:

* `table=True` tells SQLModel that this is a *table model*, it should represent a **table** in the SQL database, it's not just a *data model* (as would be any other regular Pydantic class).

Pydantic is a library to define data validation, serialization and documentation (using JSON Schema) based on Python type hints.

That makes it extremely intuitive.

* Fix handling of enums with their own schema in path parameters. To support [pydantic/pydantic#1432](https://github.com/pydantic/pydantic/pull/1432) in FastAPI. PR [#1463](https://github.com/tiangolo/fastapi/pull/1463).

## 0.55.0

* Allow enums to allow them to have their own schemas in OpenAPI. To support [pydantic/pydantic#1432](https://github.com/pydantic/pydantic/pull/1432) in FastAPI. PR [#1461](https://github.com/tiangolo/fastapi/pull/1461).

### Pydantic v1 `regex` statt `pattern`

Vor Pydantic Version 2 und vor FastAPI Version 0.100.0, war der Name des Parameters `regex` statt `pattern`, aber das ist jetzt <abbr title="deprecated – obsolet, veraltet: Es soll nicht mehr verwendet werden">deprecated</abbr>.

Sie könnten immer noch Code sehen, der den alten Namen verwendet:

If you want to secure your API, there are several better things you can do, for example:

* Make sure you have well defined Pydantic models for your request bodies and responses.
* Configure any required permissions and roles using dependencies.
* Never store plaintext passwords, only password hashes.
