❔ MVC
In MVC the model updates the view. Does that mean the code for that actual update resides within the model or in the view?

business logic resides within the model space, imagine u would have 2 different views for the same model, then u would have to implement the business logic twice
yeah i know. But at some point you would want to get data from the model to update the view right? In your exmample potentially having more than one view that would mean that the code to get that update would be in the view space right?
So that you would't have to alter the model code
well, u pass the model to the view, the view "builds itself" based on the model's data
basically all the interface logic resides in the controller, the controller then calls the respective update logic on the model and triggers the update in the view afterwards
basically in the scope of web thats: http request -> model update business logic -> render new view based on the model -> http response
basically the controller's job is to wire the stuff together
the model doesnt even know the view exists, the view doesnt know the controller exist and the controller knows both ;p
aha that makes sense
so i should put all my code for updating my View based of data recevied from a server in my view
none of it goes in the model
yes
in MVC, logic resides in the controller
the model does not update the view, the controller does
by watching for/listening to model changes
