Regarding the coding style to set at most one instance variable in a controller action, what about having using controller filters (
before_action) set instance variables?
I got that comment in response to whether or my Presenters pattern (https://github.com/justin808/fat-code-refactoring-techniques/pull/11) is justified.
Unless one uses such
before_action filters to set other instance variables, what would be other alternatives than this “presenters” pattern?
