SuperTuber TutorUserSignUpForm

forms.py

class TutorUserSignUpForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user', None)
        super(TutorUserSignUpForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        profile = Profile.objects.get(pk=self.user.pk)
        self.initial['firstname'] = profile.firstname
        self.initial['lastname'] = profile.lastname

    class Meta:
        model = TUser  # change model to TutorProfile and add bio
        fields = ['username', 'firstname', 'lastname',
                  'email', 'phone_number', 'subjects', 'image']
        widgets = {
            'username': forms.TextInput(
                attrs={
                    'class': 'form-control',
                }
            ),
            'firstname': forms.TextInput(
                attrs={
                    'class': 'form-control',
                    'value': "Hello world"

                    'class': 'form-control'
                }
            ),
            'email': forms.EmailInput(
                attrs={
                    'class': 'form-control'
                }
            ),
            'phone_number': forms.NumberInput(
                attrs={
                    'class': 'form-control'
                }
            ),
            'subjects': forms.Select(
                choices=SUBJECT_CHOICES,
                attrs={
                    'class': 'form-control'
                }
            ),
            'image': forms.ClearableFileInput(
                attrs={
                    'class': 'form-control'
                }
            ),
        }

Your views also need to be updated

class TutorRegister(CreateView):
    model = TUser
    form_class = TutorUserSignUpForm
    template_name = 'FindTutors/tutor_signup.html'  # correct form HTML

    def form_valid(self, form):
        user = form.save(commit=False)
        user.is_tutor = True
        user.save()
        return redirect('/home/tutors/')  # Go back to the table of tutors

    def get_form_kwargs(self):
        kwargs = super(TutorRegister, self).get_form_kwargs()
        kwargs.update({'user': self.request.user})
        return kwargs

Basically I'm passing the logged-in user to the form in forms.py
