Making the impossible, impossible

Sam and Ryan talk about

• Functional CSS training at EmberConf


• Some ideas for hiding styling implementation details from templates


• A new setup for multiple staging environments


• An idea from data modeling called “Making the impossible, impossible”


• How to use data down actions up effectively in forms

They also answer some listener questions:

• When should I use polymorphic or reflexive relationships?


• When do I need to explicitly name a relationship’s inverse?


• When should I reference relationships and when should I embed them?
