I'm wondering what is the current state of the art in generating a CRUD app from a data model. What out there builds scaffolding that's the easiest to work with and extend with modern JS technologies and frameworks?
If you were going to use something today, what would you pick and why?
It was a few years since I used it last and there may be something even more amazing out there now. You can easily have a large data registration system up and running in under a day. There are even 3rd party modules that extend django-admin for domain specific tasks.
Need more powerful customization? https://github.com/activescaffold/active_scaffold
According to what I've read about, getting a CRUD app up and running in Rails is as easy as 1 line in the commandline.
Is this what you are referring to?
In an fantasy world, you could generate a really shiny, really beautiful app from scaffolding. And it would be optionally hooked into all sorts of popular frameworks. Say, Angular and Bootstrap. Then you'd tweak it from there. Some framework right now might be the "closest" to that.
