AttributeError: 'Options' object has no attribute 'name'

Published: at 09:23 AM

Symptoms

Faulty code:

import graphene
from graphene_django import DjangoObjectType
from e2ecov.core.fastory.fastory_fetch import get_all_fastory_data
from e2ecov.models import FastoryDataFile


class FastoryData(DjangoObjectType):
    class Meta:
        model = FastoryDataFile


class FastoryQuery(graphene.ObjectType):
    latest_fastory_data = graphene.Field(FastoryDataFile)

    def resolve_latest_fastory_data(self, info, **kwargs):
        result = get_all_fastory_data()
        if type(result) is str:
            fastory_data = FastoryData.objects.latest('createdAt')
            return fastory_data

        return result

When splitting the main schema into files, this errors occurred when opening graphql editor:

Fix

RC was wrong model in query, the field should be of type FastoryData and not FastoryDataFile because FastoryData extends the DjangoObjectType

import graphene
from graphene_django import DjangoObjectType
from e2ecov.core.fastory.fastory_fetch import get_all_fastory_data
from e2ecov.models import FastoryDataFile


class FastoryData(DjangoObjectType):
    class Meta:
        model = FastoryDataFile


class FastoryQuery(graphene.ObjectType):
    latest_fastory_data = graphene.Field(FastoryData)

    def resolve_latest_fastory_data(self, info, **kwargs):
        result = get_all_fastory_data()
        if type(result) is str:
            fastory_data = FastoryData.objects.latest('createdAt')
            return fastory_data

        return result
