Inheritance between persisted models in loopback

Question

I'm actually trying to use loopback, and I wonder if it's possible to define a complex model architecture using inheritance like we can do with Hibernate ( Chapter 9. Inheritance mapping ).

For example, how can I define an abstract class Vehicle , a class Car that extends Vehicle and a class Truck that extends Vehicle too ?

Thank you

Answer 1

Actually, after some researches, if you use an sql database there is some posibilities :

• create those models in loopback
• create those tables in postgresql (for example)
• create a view in postgres that make wrapping of everything
• create a model in loopback binded to sql view

Several avantages

• Inheritance mapping working
• Better performances than the loopback embedded orm
