Enum.from_enum() fails with Django IntegerChoices

Current Behavior

I am working in a Django Python codebase that has a GraphQL schema. A lot of TextChoices are used in our GraphQL schema and, to properly represent these we use the provided graphene.Enum.from_enum() function.

This same approach doesn't seem to work with Django's IntegerChoices. It seems when graphene generates a GrapheneEnumType, the values are created with the IntegerChoices member names. This makes it so the IntegerChoices value cannot be represented with the generated GrapheneEnumType.

This results in an error like the following:
"Enum 'Status' cannot represent value: 2"

Expected Behavior

A value from a Django IntegerChoices object is usable to get the appropriate GrapheneEnumType value name.

motivation

To allow for graphene.Enum.from_enum() to be usable by Django's IntegerChoices class.

Environment

• Graphene Version: 3.3
• Graphene Django Version: 3.2.0
• Graphene Version: 3.3
• Django Version: 4.1.12
• Python Version: 3.10

Code Example

class Status(models.IntegerChoices):
    COMPLETED = 1, "Completed"
    IN_PROGRESS = 2, "In progress"
    ERRORED = 9, "Errored"


StatusChoices = graphene.Enum.from_enum(Status)

class Process(graphene.ObjectType):
    reference = graphene.String(description="The process reference.")
    status = graphene.Field(
        StatusChoices,
        description="Current process status.",
    )

This results in an error like the following:
"Enum 'Status' cannot represent value: 2"

graphene.Enum.from_enum() と生成された GrapheneEnumType の動作から始め、提供されている Django IntegerChoices の例を使って失敗を再現します。TextChoices と IntegerChoices の処理を比較します。1、2、9 などの値を、報告されたエラーなしに生成された Graphene enum で表現できれば、作業は完了です。
