Building a graphql schema but getting error when runserver

Using Django

I’m getting this error for my schema.py:

TypeError: ‘class Meta’ got invalid attribute(s): model,fields

I’m not sure how to get pass this issue. Here one of my models:

class AddressCountryType(DjangoObjectType):

class Meta:

  model = AddressCountry

  fields = (

    "iso_3166_1_a2",

    "iso_3166_1_a3",

    "iso_3166_1_numeric",

    "printable_name",

    "name",

    "display_order",

    "is_shipping_country",

)

Any help would greatly appreciated.

What libraries or packages are you using for this? As this isn’t something that is part of Django core, it would be helpful to get a much more complete description of your environment

i’m using:

Windows 10 Pro
Custom Built content management system built on Django-CMS & Oscar Commerce

see here for full project: bastianhilton/Alternate-CMS: Alternate CMS combines the power, extendibility, scalability, and security that Python and Django is known for. While building itself as a headless solution for any business small to enterprise. (github.com)

i’m using graphql module = Graphene
Files i’ve created includes Schema.py and Models.py after following:

www.section.io

I found the solution, turns out that the issue lied within my schema.py. One of my models didn’t have DjangoObjectType, instead it had model.models. Once corrected, the error went away.
