strawberry.pydantic.experimental.type strips all staticmethods from type definition besides from_pydantic() and to_pydantic()

[bg-radai]

When a staticmethod not named from_pydantic or to_pydantic is added to a type decorated with strawberry.pydantic.experimental.type it is not available at runtime. Attempting to call the staticmethod will result in an AttributeError.

Describe the Bug

given an example type like this:

import strawberry
from pydantic import BaseModel


class Foo(BaseModel):
    bar: int
    

@strawberry.experimental.pydantic.type(model=Foo)
class FooGQLType:
    bar: strawberry.auto

    @staticmethod
    def do_something() -> None:
        # impl doesn't matter
        pass



if __name__ == "__main__":
    FooGQLType.do_something()

Running this code will result in `AttributeError: type object 'FooGQLType' has no attribute 'do_something'

In the pydantic type wrapper the cls object is redefined here using dataclasses.make_dataclass():

strawberry/strawberry/experimental/pydantic/object_type.py

Line 248 in cafc388

cls = dataclasses.make_dataclass(

The do_something method is available as an attribute on cls before this redefinition but is unavailable afterwards.

Both to_pydantic and from_pydantic are handled as special cases. If they exist on the type definition they are saved to the namespace dict before this redefinition and re-added after the fact. if they do not exist, the default definitions are supplied

Hey, OP.

I just ran into this issue doing something similar while trying to override from_pydantic(). Were you able to find a solution to this?

Appreciate it!
