Form. py

In form, it is a field defined in models.

Next is the corresponding code in the view.

 1 @csrf_protect 2 def contact(request): 3     advice = Advice.objects.all().order_by(‘-adv_date‘) 4     if request.method == ‘POST‘: 5         form = ContactForm(request.POST) 6         if form.is_valid(): 7            project = form.cleaned_data[‘project‘] 8            subject = form.cleaned_data[‘subject‘] 9            name = form.cleaned_data[‘name‘]10            describ = form.cleaned_data[‘describ‘]11            12            Advice.objects.create(project=project, subject=subject, name=name, describ=describ)13            return HttpResponse(‘Thanks !‘)14     else:15         form = ContactForm()16     return render(request, ‘contact.html‘,{‘form‘:form,‘advice‘:advice})

Views. py

Note the @ In the first line, which is used to prevent csrf from occurring during data transmission.

The following is the method used in HTML.

1 <form action=‘contact‘ method=‘post‘>2 {% csrf_token %}3 {{ form.project}4 </form>

View code

{% Csrf_token %} still prevents csrf

"{{}}" Is a variable that is used to receive data from the corresponding field. In HTML, an input box is displayed, directed to <input>. Therefore, add your own items according to HTML.
