## Custom Validation { #custom-validation }

There could be cases where you need to do some **custom validation** that can't be done with the parameters shown above.

In those cases, you can use a **custom validator function** that is applied after the normal validation (e.g. after validating that the value is a `str`).

O mesmo aconteceria se você tivesse algo como uma <abbr title='Uma união entre vários tipos significa "qualquer um desses tipos".'>união</abbr> entre tipos diferentes onde um ou mais deles não são tipos Pydantic válidos, por exemplo, isso falharia 💥:
