Query for enum value in GraphQL

Question

Suppose I have a model like this

class Order(models.Model):
    STATES = [
        (1, 'Initiate'),
        (2, "Brief"),
        (3, "Planning"),
        (4, "Price Negotiate"),
        (5, "Executing"),
        (6, "Pending"),
        (7, "Completed"),
        (8, "Canceled"),
        (9, "Failed"),
        (10, "Paid"),
    ]

    state = models.PositiveSmallIntegerField(
        choices=STATES,
        default=1
    )

When I pair this model with its Graphene object type companion

class OrderNode(graphene_django.DjangoObjectType):
    class Meta:
        model = Order
        interfaces = (relay.Node,)

An enum type with name OrderState! is created.

I am concerned with

1. How can I query for the enums
2. How can I manage enums in React with Apollo client

For the first question, I have this query

{
  customer(id: "Q3VzdG9tZXJOb2RlOjE=") {
    name
    orders {
      edges {
        node {
          state
        }
      }
    }
  }
}

It gives me a weird state value like A_1 and A_2. I was expecting it to give me some meaningful value like "Initiate". How can I get the value of the kv pair enum?

For the second question, if I want to present to user a list of possible value for this enum, how can I do so?

I also have the similar issue. Whenever I query for a field with choices it returns capital-case value. But when I try to filter query using that value I get error \"Select a valid choice. TEST_VALUE is not one of the available choices.\", \"code\": \"invalid_choice\". It makes no sense. – Nutrition

I found a solution, though I wonder if it is the best one. In addition to the query that has enum values, I included this query

query {
    # previous queries
    __type(name: "OrderState") {
       states: enumValues {
           name
           description
       }
    }
}

It pulls all possible key-value pairs for the OrderState enum. I then can use this as a dictionary to lookup enum values.

I feel that this approach is still too manual, but there are no examples that make a query for enum values. They just stopped at describing what an enum is, and how to declare one.

Any update on making this more automagic? It seems ridiculous to both a) statically request each of these types in a query or b) dynamically fire a ton of queries for all required types – Harms
