Access to field arguments via `Info`

[rcybulski1122012]

Currently there is no easy way to access field arguments (or it's not documented well enough) outside the resolver.

Feature Request Type

• Core functionality
• Alteration (enhancement/optimization) of existing feature(s)
• New behavior

Description

In my project I implemented a function that retrieves the arguments from info object but it would be much more convenient if it was a part of Info object - it would ease the caching too.

IDK if there is a use case for that in strawberry but when using strawberry_django it would ease the filtering based on user arguments in prefetch_related and annotate.

It would require only to implement a simple property on Info class

from typing import Any

from graphql import GraphQLResolveInfo, get_argument_values
from graphql.execution.execute import get_field_def

@dataclasses.dataclass
class Info(Generic[ContextType, RootValueType]):
    ...

    @cached_property
    def field_arguments(self) -> dict[str, Any]:
        field_def = get_field_def(self._raw_info.schema, self._raw_info.parent_type, self._raw_info.field_nodes[0])

        if not field_def:
            return {}

        return get_argument_values(field_def, self._raw_info.field_nodes[0], self._raw_info.variable_values)
