Problems Saving Data to Database - django

Question

this is my views.py
def signup(request):
print "signup"
if request.method == 'POST':
print "post signup"
form = RegisterForm(request.POST)
try:
if form.is_valid():
print form.cleaned_data
u = User.objects.create_user(form.cleaned_data['emailid'], form.cleaned_data['emailid'], form.cleaned_data['passwd1'] )
ui = UserInfo()
ui.user = u
ui.class_of = form.cleaned_data['gradyear']
ui.grade = form.cleaned_data['grade']
ui.balance = 0
ui.save()
and in my forms.py i have:
class RegisterForm(forms.Form):
GRADE_CHOICES = (
(9,'9'), (10,'10'), (11,'11'), (12,'12') ,
)
curr_year = date.today().year
GRAD_YEAR_CHOICES = (
(curr_year,curr_year), (curr_year+1,curr_year+1), (curr_year+2,curr_year+2), (curr_year+3,curr_year+3) ,
)
first_name = forms.CharField(max_length = 25)
last_name = forms.CharField( max_length = 25)
emailid = forms.EmailField()
passwd1 = forms.CharField(max_length=100,widget=forms.PasswordInput)
passwd2 = forms.CharField(max_length=100,widget=forms.PasswordInput)
gradyear = forms.ChoiceField( choices=GRAD_YEAR_CHOICES)
grade = forms.ChoiceField( choices=GRADE_CHOICES)
def clean(self):
cleaned_data = super(RegisterForm, self).clean()
if cleaned_data['passwd1'] != cleaned_data['passwd2']:
raise forms.ValidationError({'passwd1':['Password do not match']})
if User.objects.filter(email=cleaned_data['emailid']).count():
raise forms.ValidationError({'emailid':['Email already taken ']})
return cleaned_data
why does everything print to the database except first_name and last_name??? (username, email, grade, gradyear, and password all save)
EDIT: This is my UserInfo
class UserInfo(models.Model):
user = models.OneToOneField(User, related_name='user_infos')
class_of = models.IntegerField()
#username = user.username
#fname = user.fname
#lname = user.last_name
#email = user.email
#Staff = user.is_staff
pub_date = models.DateTimeField( auto_now=True)
grade = models.IntegerField()
balance = models.DecimalField(max_digits=6, decimal_places=2)
#first_name = models.CharField(max_length = 25)

Answer 1

In the code provided, you never save first_name and last_name for User or UserInfo.
In def signup(request):, right after this line:
u = User.objects.create_user(form.cleaned_data['emailid'], form.cleaned_data['emailid'], form.cleaned_data['passwd1'] )
Try including this:
u.first_name = form.cleaned_data['first_name']
u.last_name = form.cleaned_data['last_name']
u.save()
