Enum name conflict for models used in both ObjectType and InputObjectType

[davidkell]

If you try to build an ObjectType and InputObjectType for pydantic models with the same enum, it tries to create the same enum twice. (This is not an issue with re-using the same enum in multiple ObjectTypes though.)

Here's a reproducible example:

import enum
import pydantic
import graphene
from graphene_pydantic import PydanticObjectType, PydanticInputObjectType

class Color(enum.Enum):
  red = 1
  green = 2
  blue = 3

class ColorModel(pydantic.BaseModel):
  color: Color

class ColorType(PydanticObjectType):
  class Meta:
    model = ColorModel

class ColorInputType(PydanticInputObjectType
):
  class Meta:
    model = ColorModel

class CreateColor(graphene.Mutation):
  class Arguments:
    data = graphene.Argument(ColorInputType)

  ok = graphene.String()

  def mutate(self, info, data):
    return ColorModel(**data)

class Query(graphene.ObjectType):
  color = graphene.Field(ColorType)

class Mutation(graphene.ObjectType):
  createColor = CreateColor.Field()

schema = graphene.Schema(query=Query, mutation=Mutation)

And the error:

     95             _type = map[type._meta.name]
     96             if isinstance(_type, GrapheneGraphQLType):
---> 97                 assert _type.graphene_type == type, (
     98                     "Found different types with the same name in the schema: {}, {}."
     99                 ).format(_type.graphene_type, type)

AssertionError: Found different types with the same name in the schema: Color, Color.

The workaround is just to manually define the enum type, but thought it would be helpful to know.

For others who got this error:

ColorEnumType = graphene.Enum.from_enum(Color)

class ColorType(PydanticObjectType):
  class Meta:
    model = ColorModel

  color = graphene.Field(ColorEnumType)

class ColorInputType(PydanticInputObjectType
):
  class Meta:
    model = ColorModel

  color = graphene.Argument(ColorEnumType)

Can we update the docs (readme) to reflect this gotcha?

I cant see any errors for your snippet, I'm missing something? (I use this repository's poetry.lock and I use Python3.10)
