Using DjangoFilterConnectionField with my own Connection

Hi guys, I’ve been trying to use DjangoFilterConnectionField with my own Connection but it only accepts DjangoObjectType. I saw that 15664bdc0b76d9118d41204922a41b808d5848ad attempts to implement it but it got reverted in 4cc46736bf7297d3f927115daedd1c332c7a38ef and after 48bcccdac2deaf3e9ad58eb0758ca9f255e3e38e I get an assertion error.

Is this no longer supported? Is there an alternate way?

Basically I’d like to add custom fields like count and have filtering support. In the code below, I can’t define count under categories unless I change to ConnectionField:

import graphene
from graphene import Node, Connection, ConnectionField
from graphene_django.types import DjangoObjectType
from graphene_django.filter import DjangoFilterConnectionField

from cookbook.ingredients.models import Category, Ingredient


class IngredientType(DjangoObjectType):
    class Meta:
        model = Ingredient
        filter_fields = ['name', 'notes', 'category']
        interfaces = (Node,)


class IngredientConnection(Connection):
    count = graphene.Int()

    class Meta:
        node = IngredientType

    def resolve_count(self, context, **kwargs):
        return self.iterable.count()

    
class CategoryType(DjangoObjectType):
    ingredients = ConnectionField(IngredientConnection)

    class Meta:
        model = Category
        filter_fields = ['name']
        interfaces = (Node,)

    @staticmethod
    def resolve_ingredients(self, context, **kwargs):
        return self.ingredients.all()

    @staticmethod
    def resolve_all(self, context, **kwargs):
        return Category.objects.all()

    
class CategoryConnection(Connection):
    count = graphene.Int()

    class Meta:
        node = CategoryType

    def resolve_count(self, context, **kwargs):
        return self.iterable.count()

    
class Query(graphene.ObjectType):
    categories = DjangoFilterConnectionField(CategoryType)
    # categories = ConnectionField(CategoryConnection, resolver=CategoryType.resolve_all)

Why did you close this issue? I am in the same trouble.

@a3ammar Thanks for adding this! I solved it with something similar, but using DjangoFilterConnectionField, here:
