Metadata associated with strawberry.input fields is not readily accessible.

[mdw00d]

Metadata annotations associated with strawberry.input classes is currently difficult to access. The following program illustrates one way that currently works to access the annotation associated with field my_value on the strawberry input class MyInput.

from typing import Annotated
from dataclasses import fields
import strawberry
from strawberry.types.base import get_object_definition

@strawberry.input
class MyInput:
    my_value: Annotated[str, strawberry.argument(metadata={"more": "meta"})]

@strawberry.type
class Query:
    @strawberry.field
    def test(
        self,
        my_input: Annotated[MyInput, strawberry.argument(metadata={"some": "meta"})],
    ) -> str:
        return "OK"

definition = get_object_definition(Query, strict=True)

print(definition.fields[0].arguments[0].metadata)

print(fields(MyInput)[0].type.__metadata__[0].metadata)

# Does not work
definition = get_object_definition(MyInput, strict=True)
print(len(definition.fields[0].metadata.items()))  # zero
print(f"{definition.fields[0].arguments=}")  # empty list

• Provide a consistent mechanism for accessing metadata annotations that works in this sort of use case
