Hi everyone, I've been thinking about web.py forms, and I realize that
it could be great if you could define a form defining a class. Something
like that:
from web import form
class MyForm(form):
name = form.Textbox('name')
password = form.Password('password')
password2 = form.Password('password2')
validator1 = form.Validator("Passwords didn't match.", lambda i:
i.password == i.password2)
and then use like normal web.py form:
f = MyForm()
f.render()
...
f.validates()
...
I write a patch to make that avaliable in current web.py.
What do you think about that?
