strawberry.UNSET

A special value that can be used to represent an unset value in a field or argument. Similar to undefined in JavaScript, this value can be used to differentiate between a field that was not set and a field that was set to None or null .

Example:

import strawberry


@strawberry.input
class UserInput:
    name: str | None = strawberry.UNSET
    age: int | None = strawberry.UNSET

In the example above, if name or age are not provided when creating a UserInput object, they will be set to UNSET instead of None . Use is UNSET to check whether a value is unset.
