The view blog.views.contacto didn't return an HttpResponse object

Question

I´m working on my first django project. I´ve been trying to create a simple contact form, but I get the error:

ValueError at /blog/contacto/ The view blog.views.contacto didn't return an HttpResponse object.

def contacto (request):
if request.method == 'POST': #Si e formulario es enviado...
    form = Formulario(request.POST)
    if form.is_valid(): #Si son validos los datos del formulario
        return HttpResponseRedirect('/blog/gracias') #redireccion a gracias
    else:
        form = Formulario() #un Unbound form

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

I don´t understand why this is happening, I´ve checked the forms documentation in django and the view I´ve done is almost identical to the one in the documentation.

Can anyone help me out?

Answer 1

Your view doesn't return an HttpResponse if request.method is not POST.

There is an indentation issue. You need to return an unbound form in case the form is not submitted:

def contacto (request):
    if request.method == 'POST': #Si e formulario es enviado...
        form = Formulario(request.POST)
        if form.is_valid(): #Si son validos los datos del formulario
            return HttpResponseRedirect('/blog/gracias') #redireccion a gracias
    else:  # <-- WATCH WHERE ELSE IS
        form = Formulario() #un Unbound form

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