How does eager_load_object_triples account for a graph?

[pmackay]

I've been trying to get eager_load_object_triples to work and finding it returned nothing initially. However when I edited this:

    else
      construct_query = "CONSTRUCT { ?o ?obj_pred ?obj_label } WHERE { <#{self.uri.to_s}> ?p ?o . ?o ?obj_pred ?obj_label }"
    end

to include a GRAPH clause in the WHERE referencing the graph the triples were stored in, it worked.

I'm sure I'm missing something very obvious here, any tips much appreciated.
