How (not) to use accessors in Eloquent
Jarek Tkaczyk wrote a blogpost on the usage of accessors in Eloquent. He demonstrates what could go wrong when using accessors on certain fields.
The moral of the story is, that data handling and its presentation should not go into the same bucket. And the model is that bucket — instead of creating accessors, traits or god knows what for this task, better use decorator (like) pattern where you can do all the necessary work for preparing your data to be displayed in your view, without touching actual values anywhere else.
Keep this in mind when you should use my pragmatic approach for presenters. Watch out for conflicting names.
