Trying to find the source of an idea I ran into a long while ago, but trying to show to a junior dev. "Push messes to the edge of your system" - I thought it was a sandi metz book or blog post, but I can't seem to find it. Anybody have any ideas?
I have a model with belongs_to :other_model and the other_model_id is set, but when I traverse that relation, it does a SELECT .... [[id, nil]] instead. Gist - https://gist.github.com/cschneid/106718d6f72e61395a291554744715b9
