That’s something else altogether. #cache_key is a bona fide general purpose model method; it’s the model identifying itself a short name that’s consistent in certain conditions.

#to_partial_path, by contrast, is strongly tied to the ActionView layer. Were it an ActiveRecord method, I’d be bothered, but Jose rightly points out that it’s ActiveModel, so could and should be implemented on presenter objects instead of AR objects.

Does a model defining #cache_key which can be leveraged by view code also break concerns? I do not think so.

It is all about duck typing. For brevity, I used an ActiveRecord object as an example, but all you need is an object that implements the Active Model API, so you don’t need to put that necessarily in your models.

Doesn’t (4) fly in the face of the separation of concerns?
