Get amount of filtered objects returned by DjangoFilterPaginateListField (before pagination)

Let me know if you'd like more code. Basically, there is no totalCount field alongside the array of ProjectType coming back in the response. Thanks for this amazing library!

A new release will be released soon, with many improvements and new features.

Hi @EmiM - I was just investigating this very thing this week and I ended up with the following solution.

DjangoListObjectField actually does filtering and pagination, and returns totalCount. Ironically, DjangoFilterPaginateListField does not. Not sure why.

class ResourceType(DjangoObjectType):
    class Meta:
        description = "Type definition for resource"
        model = Resource
        filterset_class = ResourceFilter

class ResourceListType(DjangoListObjectType):
    class Meta:
        description = "Type definition for resources uses in list queries"
        model = Resource

class Query(object):
    resource = DjangoObjectField(ResourceType)
    resources = DjangoListObjectField(ResourceListType, filterset_class=ResourceFilter, description=('All Resources query'))

I hope this helps!

Hello @EmiM and @atomboulian, thanks for asking. Sorry for the delay in responding, but the work has kept me very busy.
Could you show me a complete example where DjangoFilterPaginateListField does not return the totalCount field?
Although I propose you that try the DjangoSerializerType, since it serves both to define the types and to define the mutations based on a serializer.

Hi @eamigo86! Sorry for my delay in responding - also busy at work. Here's what we are experiencing:

class Project(AuditTrailModel):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    name = models.CharField(max_length=255)
    ref_id = models.CharField(max_length=50, blank=True, help_text="The client's personal reference identifier.")
    project_type = models.CharField(max_length=25, choices=PROJECT_TYPE_CHOICES)
    address_line_1 = models.CharField(max_length=255, blank=True)
    address_line_2 = models.CharField(max_length=255, blank=True)
    city = models.CharField(max_length=100, blank=True)
    state_province = models.CharField(max_length=255, blank=True)
    postal_code = models.CharField(max_length=10, blank=True)
    country = CountryField()
    owner = models.ForeignKey(settings.AUTH_USER_MODEL, default=get_current_user, on_delete=models.SET_DEFAULT, related_name="owned_projects")
    target_occupancy = models.DateField()

    def __str__(self):
        return self.name

class ProjectType(DjangoObjectType):
    room_count = graphene.Int()
    planned_spend = graphene.Float()
    budget_variance = graphene.Float()

    class Meta:
        description = "Type definition for project"
        model = Project
        filterset_class = ProjectFilter

class Query(object):
    project = DjangoObjectField(ProjectType)
    projects = DjangoFilterPaginateListField(ProjectType, filterset_class=ProjectFilter, description="Project list query")
