A small example is fine, but wouldn't it be better if it at least did some basic validation? How does the Arc example change if you enforce only alphanumeric characters in the input field?
class HomeController < ApplicationController
def first
if request.get?
aform 'first', [input('foo'), submit]
else
if params[:foo] && params[:foo] =~ /[A-Za-z0-9]/
session[:foo] = params[:foo]
wlink 'third', 'click here'
else
aform 'first', ["Please enter an alphanumeric string", input('foo'), submit]
end
end
end
def third
pr "you said: #{session[:foo]}"
end
end
Of course, we'll then want to allow the designers to modify the presentation, and allow the copy writers to add compelling text, etc. So, it seems like a template system is the way to go, but maybe someone has a better idea.
