Class Method Details

.items_in(circle) ⇒ Object

Return all items in the circle. Not that this could simply be done with the one line

where(:circle_id => circle.id).map{|c| c.circleable}.compact

if we were not allowing ActiveResource associations in our circles. However, given that we are, ActiveResource models have no way to automatically translate from ‘circleable’ to the model because they are missing the ‘scoped’ method. Thus, we catch that no method error and instantiate the model manually. It’s possible we could do this by opening ActiveResource, but I thought this was less intrusive
