BigIntegerField should convert to Float?

I’m not sure what the best solution to this would be, but converting models.BigIntegerField() to graphene.Int() will often give me the error.

{
  "errors": [
    {
      "message": "Int cannot represent non 32-bit signed integer value: 2554208328"
    }
  ],
  "data": {
    "match": null
  }
}

Maybe we would be better off converting it to a graphene.Float()?

Thanks @brianjp93, this is still an issue in 2021 😅

You can register the custom field so it uses it automatically for every models.BigIntegerField. Run the following in an app -> ready method for example.

from django.apps import AppConfig
from django.db import models
from graphene import Field
from graphene_django.converter import convert_django_field

from .types import BigInt


class MainConfig(AppConfig):
    ...

    def ready(self):
        super().ready()

        @convert_django_field.register(models.BigIntegerField)
        def convert_field_to_big_int_field(field, registry=None):
            return Field(BigInt, description=field.help_text, required=not field.null)

you might want to create your own scalar for big integers.
