Today I Learned

Reminded of a proposal I made long ago. For responsive design, start at one size, and head in one direction, using either min-width or max-width, but not both.

I spent time today moving some behavior of a model into a concern, specific to that model. Rather than putting it into app/models/concerns/person_pending_request_count I put it into app/models/person/pending_request_count. I liked this change, because it communicated that only Person should be using this. It’s not a general mixin, though it could easily become one. Then in the person class, I just included it with include Person::PendingRequestCount.
