Short demonstration of using prefixed collections when using graph stuff in Foxx

graph.js

var relationName = applicationContext.collectionName("containsX");
var vertexCollectionName = applicationContext.collectionName("X");
var graph_module = require("org/arangodb/general-graph");
var sampleGraph = graph_module._graph("sampleGraph");
var contactSpaceGraph = graph_module._graph("sampleGraph");
var vertex = contactSpaceGraph._getVertexCollectionByName(vertexCollectionName);
var edge = contactSpaceGraph._getEdgeCollectionByName(relationName);
var Foxx = require("org/arangodb/foxx");

var controller = new Foxx.Controller(applicationContext);

controller.get('/vars', function (req, res) {
  res.json({
    vertex: vertexCollectionName,
    relation: relationName
  });
});
