I'd like to pull the values for capacity and the slots left from a registration created by the entity registration module. This sets up registration entities which are attached to (I believe this is how it works - my familiarity with the entity system is only so-so at this point, but I'm actively learning) nodes.
I'm creating a view for the event nodes, I would like to display these fields - how would I go about doing that? Would I create a relationship of some sort in the view?
What's the standard method to pull another, related entity's content into a node entity?
