I think this is not really what you want, but could help: you can
validate data (using validators) if you use helpers to create your
forms. Creating forms with helpers is more flexible than with Crud.
Try something like this:
def test():
f = FORM('Is web2py cool? Why?',
SELECT(OPTION('Yes', _value='y'), OPTION('No',
_value='n'), _name='opts', requires=IS_IN_SET(['y'],
error_message='Errr...wrong answer')),
INPUT(_type='text', _name='why', _value="'cause python
rules", requires=IS_NOT_EMPTY()),
INPUT(_type='submit', _name='btnSubmit', _value='ok'))
if f.accepts(request.vars):
response.flash = 'form accepted'
elif request.vars.btnSubmit:
response.flash = 'error in form'
return dict(myform=f, v=request.vars)
You can create the layout in HTML and elements in controller (INPUT,
SELECT etc.) and then put them in HTML with {{=varname}}.
