I have SQLAlchemy model with some enum:
variants = ('red', 'green', 'yellow')
my_enum_type = sqlalchemy.dialects.postgresql.ENUM(*variants)
class CarModel(Base):
color = sqlalchemy.Column(my_enum_type)
and graphene Schema which uses SQLAlchemyObjectType:
class Car(SQLAlchemyObjectType):
class Meta:
model = CarModel
I want to create a mutation:
class CreateCar(graphene.Mutation):
class Arguments:
color = Car._meta.fields['color'].type
...
def mutate(self, info, color):
db_session.add(CarModel(color=color))
db_session.commit()
return ...
There are two issues:
(Minor) I refer to enum in a strange way: .._meta.fields.., but it is known issue: Proper support for the SQLAlchemy Enum type #78
(Major) If I try to execute program with such schema, I get error:
File "contrib/python/graphene/graphene/types/argument.py", line 67, in to_arguments
raise ValueError('Unknown argument "{}".'.format(default_name))
ValueError: Unknown argument "color"
If I add nullable=False to SQLAlchemy model, everything works fine.
