Hello,
I have searched through much of the mailing list, all of the
documentation I could find, Google, and tried the freenode channel
(which seems to be dead). I can not find out what the purpose is of
having form.notnull inside of the form objects' constructors. The only
description of it that I could find is at webpy.org/form#inputfeatures
but it wasn't very clear:
form.textbox("firstname",
form.notnull, #put validators first followed by optional
attributes
class_="textEntry", #gives a class name to the text box -- note
the underscore
pre="pre", #directly before the text box
post="post", #directly after the text box
description="please enter your name", #describes field, defaults
to form name ("firstname")
value="bob", #default value
id="nameid", #specify the id
)
Could anyone tell me what the purpose of form.notnull is? Or point me
to some literature I missed that explains it to me?
