My Models

class ContactUs(models.Model):
    name = models.CharField(max_length=120)
    email = models.EmailField(max_length=120)
    subject = models.TextField(max_length=200)
    message = models.TextField(max_length=1000)

My Template

<div class="col-md-8">
                        <h4 class="m-t-0">Contact Form</h4>
                        <p class="m-b-30 f-s-13">

                            {{form.as_p}}

                            <div class="form-group">
                                <div class="col-md-offset-3 col-md-7">

                            </div>
                        </form>
                    </div>

My Forms

class ContactForm(forms.ModelForm):
    class Meta:
        model = ContactUs
        fields = '__all__'
        widgets = {
            'name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Name'}),
            'email': forms.EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email'}),
            'subject': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Subject'}),
            'message': forms.Textarea(attrs={'class': 'form-control', 'rows': 10, 'placeholder': 'Message'}),
        }

My VIews

class ContactTemplate(FormView):
    template_name = 'contact_us.html'
    form_class = ContactForm
    success_url = '/products/'

    def form_valid(self, form):
        # Handle form submission
        form.save()
        return super().form_valid(form)

Please confirm what the specific block of lines are that are identified by the error message:

So maybe post here everything between lines 102 and 122 of the shope/views.py file.

It may also be helpful if you posted the full traceback message from your runserver console log.
