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

If you want to receive partial updates, it's very useful to use the parameter `exclude_unset` in Pydantic's model's `.model_dump()`.

// such that the number of entries from updates does not exceed f.maxUpdateManagers.
func (f *capManagersManager) capUpdateManagers(managed Managed) (newManaged Managed, err error) {
	// Gather all entries from updates
	updaters := []string{}
	for manager, fields := range managed.Fields() {
		if !fields.Applied() {
			updaters = append(updaters, manager)
		}
	}
	if len(updaters) <= f.maxUpdateManagers {
		return managed, nil
	}
