I’d say it’s unnecessary cluttering to the API, and could collide with someone using model_name in any sort of model already out there.
I think you may be overlooking the way to create your “super simple object”, probably one of these two would work quite fine:
Class.new(OpenStruct) do
def self.model_name
@model_name ||= ActiveModel::Name.new(self)
end
def self.name
“User”
end
end
Class.new(OpenStruct) do
def self.name
“User”
end
extend ActiveModel::Naming
end
Also, I don’t see why you couldn’t just create a real class and extend Naming on it, should work just fine :).
