Draper is a Ruby gem that adds a decorator/view-model layer to Rails applications. It wraps ActiveRecord models with presentation-specific logic, keeping views clean and models free of display concerns.
Use cases
- move view helper logic into testable objects
- format dates and statuses for display in Rails views
- keep presentation logic out of ActiveRecord models
- organize view-model code for complex Rails UIs
- replace global helper methods with object-oriented decorators
When to choose
- you have a Rails app with presentation logic cluttering models or helpers
- you want testable, object-oriented view logic
- you need per-model display formatting without helper namespace pollution
When to avoid
- you use Sinatra, Hanami, or a non-Rails Ruby framework
- your views are simple and helpers suffice
- you prefer a different view-model pattern like plain POROs or ViewComponents
