[Django]-Passing a Django form to a template tag

by

✅

When using inclusion_tag, you shouldn’t call render yourself. You should return the context dictionary (for example: return {'form': form}) – Django will then take care of rendering the template you named in the @register.inclusion_tag('demo_form.html') declaration.

I would advise against trying to handle the if request.method == 'POST': logic within the tag, as that will be triggered any time any page on your site is rendered in response to a POST request – regardless of whether the POST request had anything to do with your DemoForm. Instead, you should set up a Django view to handle those form submissions, and put the URL to that view in the form’s action attribute.

What is returned when the request is not a POST or is_valid() is false? I typically use a pattern like this (note the changes at the end):

from .forms import DemoForm

register = template.Library()

@register.inclusion_tag('demo_form.html')
def book_a_demo(request):
    form = DemoForm

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

        if demo_form.is_valid():
            contact_name = request.POST.get('name', '')
            company_name = request.POST.get('company', '')
            contact_email = request.POST.get('email', '')
            contact_phone = request.POST.get('phone', '')

            # Email the profile with the
            # contact information
            template = get_template('contact_template.txt')
            context = Context({
                'contact_name': contact_name,
                'company_name': company_name,
                'contact_email': contact_email,
                'contact_phone': contact_phone,
            })
            content = template.render(context)

            email = EmailMessage(
                "Request to Book a Demo",
                content,
                "domain" +'',
                ['example@email.com'],
                headers = {'Reply-To': contact_email }
            )
            email.send()
            return render(request, 'demo_form_landing.html')
    else:
        demo_form = form()

    return render(request, 'demo_form.html', {'form': demo_form})
