clear enough for callback function, thank you so much for detail
explaination, anthony, better to move it to modules, it didnt appear in
snakeviz result when it's not called
for current i understand the reason, but when i move it to lambda or
function without arguments, it return an error.
*e.g.*
*modules/test_field_constructor.py*
#requires_date = lambda: IS_DATE(format = current.T('%Y-%m-%d'),
error_message = current.T('Enter date as yyyy-mm-dd') )
def requires_date():
return IS_DATE(format = current.T('%Y-%m-%d'), error_message =
current.T('Enter date as yyyy-mm-dd') )
*controllers/default.py*
def test_form():
redirect_url = 'test'
form = SQLFORM.factory(
Field("from_date", "date",
requires = test_field_constructor.requires_date) )
if form.process().accepted:
from_date = form.vars.from_date
response.new_window = URL(redirect_url, args = from_date)
elif form.errors:
response.flash = T('Form has errors')
return dict(form = form)
*error traceback :*
raise Exception(msg)
Exception: Validation error, field:from_date <function <lambda> at
0x10e9d6c80>
any idea how to use lambda or function without arguments in web2py modules?
thanks and best regards,
stifan
