将has_many添加到ActiveModel :: Serializer时出现问题

Question

I've been trying to add has_many relationships to my ActiveModel::Serializers for a while now and I'm getting a bevy of errors related to them. It seems like the has_many relationships are calling the wrong serializer. Here is the error:

So it turns out that using :option as a property name was causing conflicts. There are probably other conflicting names as well. Gotta be careful about the namespace!
