Access information from parent node in custom edge resolver

[dbstratta]

Hi! I have an Organization type that has a field members, which is a connection of Users, but with a custom edge type. The custom edge type has a role field, apart from the standard node field.

This is the query I would like to perform:

{
  organization(name: "org1") {
    members(first: 10) {
      edges {
        role
        node {
          username
          email
        }
      }
    }
  }
}

And this is my current connection type definition:

connection node_type: :organization_member do
  edge do
    field :node, non_null(:user)

    field :role, non_null(:string) do
      resolve fn
        %{node: user}, _, _ ->
          {:ok, Organizations.get_member_role(organization_id, user.id)}
      end
    end
  end 
end

I need the organization_id inside the resolver function of the edge, but I couldn't find a way to access the parent node information. Is there a way I can do that?

Just in case, this is my Organization type:

node object :organization do
  # ...

  connection field :members, node_type: :organization_member do
    resolve &Resolvers.Organizations.resolve_members/3
  end

  # ...
end

Thanks for the awesome work!

A year later! I have the same issue with setting up totalCount on the connection:

parent in this case is the whole connection object, then I think we need to fetch parent of parent, or?

  connection node_type: :profile do

    field :total_count, non_null(:integer) do
      resolve fn parent, _args, _resolution ->
        # parent is empty? return Profile.count else:
        count = Ecto.assoc(parent, :profiles) |> Repo.aggregate(:count, :id)
        {:ok, count}
      end
    end

    edge do
    end

  end

maybe @benwilson512 has any comment on this?
