The register function, as all the functions in auch which return a form,
call process internally. Therefore if you fo
form = auth.register()
form.process()
you would be calling process twice with undesired consequences. Moreover if
the process() called inside it successful and the form was accepted you may
have a redirect (raise HTTP) and therefore the function never returns.
I think this is what you want:
def register():
def onvalidation(form):
if form.errors: # form has errors
session.flash = 'Registration form processed, please check your
email'
def onaccept(form): # form accepted
response.flash = 'Registration form contains error(s)'
auth.settings.register_onvalidation.append(onvalidation)
auth.settings.register_onaccept.append(onaccept)
form = auth.register()
if not form.vars: # form not sumitted
response.flash = 'Please fill in the registration form'
return dict(form=form)
Anyway if all you want is set errors, you should use auth.messages.*
2.
open a web2py shell with
python web2py.py -S welcome -M -N
then experiment yourself
form = auth.register()
print form
form['_class'] = 'test'
print form
form.element('input[name=myfield]')['_class'] = 'test' # jquery syntax
print form
