I am trying to get a specific data model after I run an aggregate pipeline followed by populate but I am falling just short of it.

Can you populate an array in a mongoose schema with references to a few different schema options? To clarify the question a bit, say I have the following schemas: var scenarioSchema = Schema({ _id : Number, name : String, guns : [] }); var ak47 = Schema({ _id : Number //Bunch of AK specific parameters }); var m16 = Schema({ _id : Number //Bunch of M16 specific parameters }); Can I populate the guns array with a bunch of ak47 OR m16?
