How should records, methods be added or code injected into -Entries class?

[siers]

In the spirit of #3, I'm wondering how I could add the ActiveStorage accessors for has_many_attached?

In the #3 it was said that you could add a belongs_to to the model, but in this case the accessors and relations should really be added to the parent.

Wouldn't it make more sense to create a real, generated model inside app/models, since that would also make autoloading work as expected (i.e. I don't have to load Article to instantiate ArticleDetailsEntry or similar)

So perhaps it should just be just ArticleDetailsEntry.class_exec do has_many_attached :files end after instantiating Article? :) If so, this issue might serve as documentation.
