Integrating django-registration-redux along with custom_user: Prevent user registration if UserProfile is not valid

I'm trying to use django-registration-redux along with custom_user. I have added both apps to settings.py

My main urls.py is as given below

from userprofile.forms import UserProfileForm  from registration.backends.default.views import RegistrationView  urlpatterns = [  url(r'user/register/$',           RegistrationView.as_view(form_class = UserProfileForm),           name = 'registration_register'),        url(r'^user/', include('registration.backends.default.urls')),  ]  

I have a UserProfile model as given below. (userprofile/models.py)

def validate_dob(value):      now=timezone.now()      start_date=date(now.year-settings.AGE_UPPER, 1, 1)      end_date=date(now.year-settings.AGE_LOWER, 12, 31)      print("start: %s end: %s supplied :%s" % (start_date, end_date, value))      if start_date >value or value > end_date:              raise ValidationError("Please choose a valid date from the given set")   #----------------------------------------  class UserProfile(models.Model):      user=models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE,          primary_key=True,)      fullname=models.CharField(max_length=70, blank=False)      dob=models.DateField(blank=False,validators=[validate_dob] )      photo=models.ImageField(upload_to='profile_images', blank=False)      def __str__(self):          return self.user.email      def get_profile(self):          return self.user.id  #---adding signal to save UserProfile  def user_registered_callback(sender, user, request, **kwargs):      profile = UserProfile(user = user)      print(request.POST)      profile.fullname =request.POST["fullname"]      profile.dob ="%s-%s-%s" % (request.POST["dob_year"],request.POST["dob_month"],request.POST["dob_day"])      #profile.dob=request.POST["dob"]      if 'photo' in request.FILES:          profile.photo = request.FILES['photo']        profile.save()    user_registered.connect(user_registered_callback)  

and here's my userprofile/forms.py

class UserProfileForm(RegistrationForm):      fullname=forms.CharField(required=True,label="Full name",  min_length=3, max_length=75)      dob=forms.DateField(required=True,label="Date of birth",           widget=forms.SelectDateWidget(years=range(now.year-settings.AGE_UPPER,now.year-settings.AGE_LOWER)))        photo=forms.ImageField(required=True)`  

How do I prevent inserting User values into the table if the filed, say dob is not in the specified range (AGE_UPPER=70 ,AGE_LOWER=18)

Please tell me if I'm making this over complicated.

Thanks
