将我的def视图转换为基于类的视图

I have this view in my app:

我的应用程序中有这个视图：

def contact(request):
    form_class = ContactForm

    if request.method == 'POST':
        form = form_class(data=request.POST)

        if form.is_valid():
            contact_name = form.cleaned_data['contact_name']
            contact_email = form.cleaned_data['contact_email']
            contact_website = form.cleaned_data['contact_website']
            contact_subject = form.cleaned_data['contact_subject']
            form_content = form.cleaned_data['content']

            template = get_template('contact/contact_template.txt')
            context = Context({'contact_name': contact_name,
                               'contact_email': contact_email,
                               'contact_website': contact_website,
                               'contact_subject': contact_subject,
                               'form_content': form_content, })
            content = template.render(context)

            email = EmailMessage(
                "New contact form submission",
                content,
                "www.inexistente.com" + '<[email protected]>',
                ['[email protected]'],
                headers={'Reply-To': contact_email}
            )
            email.send()
            return redirect('/')

    return render(request, 'contact/contact.html', {'form': form_class, })
