@diox What do you think about https://github.com/nearlyfreeapps/zamboni/commit/d48be0da714c1b15926f27a3ddfbe957f610a106? I didn't want to move the method into `FireplaceAppSerializer` since `FireplaceAppSerializer` and `FireplaceESAppSerializer` inherit from different from different classes but I may have thought about that incorrectly.
