Polymorphism in Other Frameworks
Explore how polymorphism is implemented in frameworks like ActiveRecord and Laravel, including their conventions and limitations. Understand why Ecto avoids this method due to integrity and performance concerns. Learn the fundamentals to implement polymorphic associations effectively in Ecto.
