`PATCH` is less commonly used and known than `PUT`.

And many teams use only `PUT`, even for partial updates.

You are **free** to use them however you want, **FastAPI** doesn't impose any restrictions.

But this guide shows you, more or less, how they are intended to be used.

### Using Pydantic's `exclude_unset` parameter { #using-pydantics-exclude-unset-parameter }

However, for the vast majority of issues, we aim to empower individuals to first resolve conflicts themselves, asking for help when needed, and only after that fails to escalate further. This approach gives people more control over the outcome of their dispute. 

If you are experiencing or witnessing conflict, we ask you to use the following escalation strategy to address the conflict:

1.  Address the perceived conflict directly with those involved, preferably in a

 * construction.
 *
 * <p>This class is primarily used for creating URI escapers in {@link UrlEscapers} but can be used
 * directly if required. While URI escapers impose specific semantics on which characters are
 * considered 'safe', this class has a minimal set of restrictions.
 *
 * <p>When escaping a String, the following rules apply:
 *
 * <ul>

C'est un outil formidable et je l'ai beaucoup utilisé aussi, avant d'avoir **FastAPI**.
