How do traditional web development frameworks cope with RIAs?
By RIAs, I am referring to the Flex/Silverlight model (Ajax has a hybrid model in my view, so I'm not discussing that here since I don't want to muddle up the question).
Coming back to topic, I see that the traditional web development frameworks are inside-out and RIA development as outside-in:
|Traditional web dev frameworks||RIA frameworks|
|Flow: controller ⇒ model ⇒ view (pages)||view ⇒ controller ⇒ model||
Everything built into the framework. View is generated via templates.
View is designed separately and it's what runs first. Backend is a bunch of web services.
Question: How is this resolved practically?
For example, how do people using Django or Ruby on Rails actually write, say, Flex frontends for their websites?
Do they ditch their templates/rhtml? Do they design the RIA first and then the web service, or the other way around? ... etc.
I couldn't figure out the answer and since there are people out there doing it, I'm hoping the "hoosgot" i.e. lazy web gods will answer.
