adding count to query

I’m using the following code and would like to to have variable “count” (number of total results) in my response – but I have no idea on how to solve it (already did quite some research).

class EntryNode(DjangoNode):
    class Meta:
        model = Entry


class Query(ObjectType):
    all_entries = DjangoFilterConnectionField(EntryNode)

    class Meta:
        abstract = True

Query

{allEntries(first:5) {
    pageInfo{hasPreviousPage, hasNextPage},
    edges{node{id,user{id,username},title,category{id,name}}}
}}

Results I’d like to have an additional variable “count” (either within “allEntries” or even better as a part of “pageInfo”)

{
    "data": {
        "allEntries": {
            "pageInfo": {
                "hasPreviousPage": false,
                "hasNextPage": false,
                "count": ???,
            },
            "count": ???,
            "edges": [
                {
                    "node": {
                        "id": "RW50cnlOb2RlOjUy",
                        ...
                    }
                }
            ]
        }
    }
}

Hi @sehmaschine, this is how I approached the same issue in swapi-graphene.

Example swapi-graphene totalCount query.

{
  myFavoriteFilm: film(id:"RmlsbToz") {
    id
    title
    episodeId
    characters(first:5) {
      totalCount
      edges {
        node {
          name
        }
      }
    }
  }
}

Implementation: https://github.com/graphql-python/swapi-graphene/blob/master/starwars/schema.py#L18-L22

And then use connection_type in your EntryNode:

class EntryNode(DjangoNode):
    class Meta:
        model = Entry

    connection_type = Connection

Hope it helps!

I arrived here by Google first but ultimately found the total_count implementation at this thread easier to follow and use: https://github.com/graphql-python/graphene-django/issues/162

from graphene import Int

class ProductNode(DjangoObjectType):
    class Meta:
        model = Product
        filter_fields = {
            'name': ['exact', 'icontains', 'istartswith'],
        }
        interfaces = (relay.Node, )

    @classmethod
    def get_connection(cls):
        class CountableConnection(relay.Connection):
            total_count = Int()

            class Meta:
                name = '{}Connection'.format(cls._meta.name)
                node = cls
            
            @staticmethod  # Redundant since Graphene kinda does this automatically for all resolve_ methods.
            def resolve_total_count(root, args, context, info):
                return root.length

        return CountableConnection
