Want to add another field to form and database django - django

Question

I tried adding another field (pin) in forms.py and models.py
The error i got was
"FieldError at /student/signup/
Cannot resolve keyword 'pin' into field. Choices are: date_joined, email, first_name, groups, id, is_active, is_staff, is_superuser, last_login, last_name, logentry, password, user_infos, user_permissions, username"
forms.py
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)
pin = forms.IntegerField()
def clean(self):
cleaned_data = super(RegisterForm, self).clean()
print cleaned_data
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 ']})
if User.objects.filter(pin=cleaned_data['pin']).count():
raise forms.ValidationError({'pin':['Pin already taken ']})
return cleaned_data
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
print "Hi"
ui.pin = form.cleaned_data['pin']
print ui.pin
u.first_name = form.cleaned_data['first_name']
u.last_name = form.cleaned_data['last_name']
u.save()
ui.save()
user = authenticate(username=form.cleaned_data['emailid'], password=form.cleaned_data['passwd1'])
login(request,user)
print "after login in signup"
return redirect("/")
else:
print "error"
print form.errors
except:
raise
print "error here"
print form.errors
pass
#return render(request, 'student/register.html', {'form': form})
else:
form = RegisterForm()
return render(request, 'student/register.html', {'form': form})
models.py:
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)
pin = models.IntegerField()
#first_name = models.CharField(max_length = 25)
I don't think not be doing this right. Is there any way to add another column in a database another way?

Answer 1

You have "pin" field in your UserInfo model, but in forms.py you are trying to filter User model:
if User.objects.filter(pin=cleaned_data['pin']).count():
User model does not have "pin" field, so you are getting that error message.
Also I suggest you to learn and start using ModelForms: https://docs.djangoproject.com/en/1.8/topics/forms/modelforms/
