resolve_[field_name] not working for DjangoListObjectField

[tadeo]

@eamigo86 Exploring for alternatives I found that I can use a FilterSet class to filter the queryset with its filter_queryset(self, queryset) method, having the request available at self.request.
Here the alternative way of intervening the queryset:

class Product(models.Model):
    owner = models.ForeignKey(settings.AUTH_USER_MODEL)
    name = models.CharField(max_length=255)
    discontinued = models.BooleanField(default=False)


class ProductListType(DjangoListObjectType):
    class Meta:
        model = Product
        pagination = LimitOffsetGraphqlPagination()


class ProductFilter(django_filters.FilterSet):
    class Meta:
        model = Product

    def filter_queryset(self, queryset):
          # here I am able to filter the queryset with the request
        queryset = queryset.filter(discontinued=False, owner=self.request.user)
        return queryset


class Query(graphene.ObjectType):
    all_products = DjangoListObjectField(ProductListType, filterset_class=ProductFilter)

Gracias!

I’m also very interested in this.

I want to use it with https://github.com/flavors/django-graphql-jwt

Hi @tadeo, sorry about that, but it's a pending work that I have to do, which one will be available very soon.

Hi, I also have the need for resolve_[field] in order to add queryset annotations to my type, which isn't quite solved by #15 , i.e:

class SystemType(DjangoObjectType):

    version = graphene.Int()
    warning_count = graphene.Int()

    class Meta:
        model = System
        filterset_class = SystemFilter


class SystemListType(DjangoListObjectType):

    version = graphene.Int()
    warning_count = graphene.Int()

    class Meta:
        model = System
        pagination = PageGraphqlPagination(page_size=20)
        filterset_class = SystemFilter


class Query(object):
    systems = DjangoListObjectField(SystemListType)
    system = DjangoObjectField(SystemType)

    def resolve_systems(self, info, **kwargs):
        return System.objects\
            .add_version_number()\
            .add_warning_count()

Thanks!

@gregbrowndev just curious, did you try the filterset_class workaround I suggest?

[gsiegman]

@tadeo I attempted your solution, however when making a GraphQL query, my filterset's filter_queryset method never gets called. Is there anything additional you had to do beyond what is showing in your code above?

[gsiegman]

@aldarund that did it, thank you!

@cfarvidson, if you still interested in using django-graphql-jwt with this library, you can check the request #176.

Thanks. Sadly I’ve abandoned the Django project that I used JWT in. 🙂
