Lowercased choices getting uppercased in Graphene response

I’ve the following model:

class TripSuggestedGadget(models.Model):
    trip = models.ForeignKey(
        Trip,
        related_name='suggested_gadgets'
    )
    type = models.CharField(
        max_length=50,
        choices=SUGGESTED_GADGET_TYPES
    )
    description = models.TextField()

Here are the choices referred above:

SUGGESTED_GADGET_TYPES = (
    ('camera', u'Cámara'),
    ('flash', u'Flash'),
    ('tripod', u'Trípode'),
    ('umbrella', u'Sombrilla'),
)

In the graph response here’s what I’m getting:

...
"edges": [
    {
        "node": {
            "id": "VHJpcFN1Z2dlc3RlZEdhZGdldE5vZGU6MQ==",
            "type": "CAMERA",
            "description": "Cámara de formato medio",
            "__typename": "TripSuggestedGadgetNode"
        },
        "__typename": "TripSuggestedGadgetNodeEdge"
    },
    {
        "node": {
            "id": "VHJpcFN1Z2dlc3RlZEdhZGdldE5vZGU6Mg==",
            "type": "FLASH",
            "description": "Flash",
            "__typename": "TripSuggestedGadgetNode"
        },
        "__typename": "TripSuggestedGadgetNodeEdge"
    },
    {
        "node": {
            "id": "VHJpcFN1Z2dlc3RlZEdhZGdldE5vZGU6Mw==",
            "type": "TRIPOD",
            "description": "Trípode liviano para poderlo llevar",
            "__typename": "TripSuggestedGadgetNode"
        },
        "__typename": "TripSuggestedGadgetNodeEdge"
    }
]
...

As you may notice my choices are lowercased, but response uppercased.

I’ve seen @BrianChapman comment in #67 regarding the same problem, but preferred to open this new one because #67 is not directly related.

Adding the field as a String, seems to be enough to solve the problem.

class MyObject(DjangoObjectType):
   type = graphene.String()

Just ran into this issue too and was very confused that Graphene was forcing all my enum string values to uppercase. Given that Django itself treats enum strings used as choices as being case-sensitive, and doesn’t force them to be uppercase, I think it’s important that Graphene doesn’t try to force them to be uppercase.

If GraphQL recommends string constants be uppercase, perhaps it’s worth mentioning this as a suggestion in the Graphene docs somewhere, but I think the choice needs to be left to the developer.

In the meantime, @Hispar’s fix of marking the field as being a String() is working for me.
