fix: move EventHelper from app/helpers to app/models/concerns#2702
Merged
Conversation
EventHelper contains model validation logic (venue_or_remote_must_be_present, sponsors_uniqueness, etc.) operating on model state, making it a concern rather than a view helper. Moving it to app/models/concerns/ fixes a presentation-to-domain layer violation. The include EventHelper line in Event does not change — Rails autoloading resolves the module from app/models/concerns/ under the same name.

Problem
EventHelperlived inapp/helpers/(Presentation layer per Rails conventions) but is included in theEventmodel (Domain layer). It defines model validation methods (sponsors_uniqueness,venue_or_remote_must_be_present, etc.) operating on model state — a presentation-to-domain layer violation.Solution
Move
EventHelperfromapp/helpers/event_helper.rbtoapp/models/concerns/event_helper.rb. Theinclude EventHelperinapp/models/event.rbis unchanged — Rails autoloading resolves the module fromapp/models/concerns/under the same name.Verification
