Description
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)Metadata
