Registration of a custom user in Django

Question

I'm trying to set a sign up page for a project. I created a custom user class adding few optional fields: I'm using Django 1.5 and Python 2.7

class CustomUser(models.Model):
    middleschool = 'MS'
    highschool = 'HS'
    university = 'U'
    blank = '-'
    male = 'M'
    female = 'F'

    school_choices = ((middleschool, 'Middle School'), (highschool, 'High school'), (university, 'University'), (blank, 'Not defined'),)
    sex = ((male, 'Male'), (female, 'Female'), (blank, 'Not defined'),)

    user = models.ForeignKey(User, unique=True)
    school = models.CharField(max_length = 30, choices = school_choices, default = blank, blank=True, null=True) 
    birthdate = models.DateField(blank=True, null=True)
    sex = models.CharField(max_length = 1, choices = sex, default = blank, blank=True, null=True)
    city = models.CharField(max_length = 30, blank=True, null=True)
    payment_info = models.BigIntegerField(max_length = 30, blank=True, null=True)
    rating = models.DecimalField(max_digits=2, decimal_places=0, default = 0)
    premiumstatus = models.BooleanField(default = False, blank=False, null=False)

and added a create_user method as found here . This is the model's method:

def create_user(sender, instance, created, **kwargs):
    if created:
        CustomUser.objects.create(user=instance)
post_save.connect(create_user, sender=User)

this is the relative view:

def registration(request):
    if request.method == 'POST':
        form = Registration(request.POST)
        if form.is_valid():
            cd =form.cleaned_data
            fuser = cd['username']
            fpassword = cd['password']
            femail = cd['email']
            fname = cd['name']
            fsurname = cd['surname']
            fschool = cd['school']
            fbday = cd['birthdate']
            fsex = cd['sex']
            fcity = cd['city']

            user = User.objects.create_user(fuser, fpassword, femail)

            user.is_active = True
            user.save()
            return HttpResponseRedirect("/home/")
    else:
        form = Registration()
    return render(request, "registration.html", {'form': form})

and the relative form:

class Registration(forms.Form):
    middleschool = 'MS'
    highschool = 'HS'
    university = 'U'
    blank = '-'
    male = 'M'
    female = 'F'

    school_choices = ((middleschool, 'Middle School'), (highschool, 'High school'), (university, 'University'), (blank, 'Not defined'),)
    sex = ((male, 'Male'), (female, 'Female'), (blank, 'Not defined'),)

    username = forms.CharField(label = 'Username')
    password = forms.CharField(label = 'Password', widget=forms.PasswordInput)
    repassword = forms.CharField(label = ' Reinstert password', widget=forms.PasswordInput)
    email = forms.EmailField()
    name = forms.CharField(label = 'Name', required=False)
    surname = forms.CharField(label = 'Surname', required=False)
    school = forms.ChoiceField(choices = school_choices, required=False, label='What school are you enrolled?') 
    birthdate = forms.DateField(label = 'Birth date', required=False)
    sex = forms.ChoiceField(choices = sex, required=False, label='Sex')
    city = forms.CharField(label = 'City', required=False)

    def clean_repassword(self):
        repassword = self.cleaned_data['repassword']
        password = self.cleaned_data['password']
        if repassword != password:
            raise forms.ValidationError("Verification password different from original password!")
    widgets = {
            'password': forms.PasswordInput(),
    }

Now, the problem are basically two: I'm still a beginner so I dont' really understand how create_user works, I tried to pass fname and fsurname as an argument of said method but it wont work, it tells me that only four arguments are accepted. Second, if i try to add any optionl info with the command showed in the link:

user.get_profil().sex = fsex

it dosen't raise any error but doesn't work either.

Answer 1

user.get_profile().sex = fsex

You have to assign users profile to a variable to be able to modify it:

profile = user.get_profile()
profile.sex = fsex
profile.save()

Update Try to explicitly specify field keys when creating user, like this:

user = User.objects.create_user(username=fuser, email=femail)
user.set_password(fpassword)
