What usually happens is that Rails has a built-in support for simple cases which actually is more complicated than form == data row. And for even more complex scenarios you end up with "fake models" that look&act exactly like FormEncode forms. This isn't quite as elegant as Pylons design but ends up being more practical, at least in my experience. > It still baffles me why Rails (and I guess Django?) works this way, I can > understand the simple use-case, but I so rarely see forms out there that > actually satisfy this simple use-case except in simple demo apps for > learning the framework. > > How come people don't get pissed that they can't validate their form data > *before* they go to the effort of setting up the actual model instances and > preparing to save them?

I guess the reason I'm not a big fan of FormEncode is because it defaults to the 3rd approach. And, again, I myself don't have a better design/approach to suggest, without tying together html helpers and models. Perhaps it wasn't the best idea coming from me today to even start this discussion: I really have nothing constructive to contribute! ;-) -- You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
