Calling a special (non-HTTP) URL from the form_valid method of the Django class

Here is this HTML trick, where, if you do <a href="sms:14085551212?body=Hello my friend">New SMS Message</a>, by clicking New SMS , your phone’s own SMS application opens and fills the field with a Tonumber (1-408 -555-1212 in this case) and bodywith the message provided ( Hello my friendin this case).

Is it possible to somehow call the same line hreffrom a form_validclass method based on the Django class? More precisely, in this method form_validI get a variable POSTthat is uuid. I need to use this uuidin the bodyhref line section that I wrote in the above example.

Note. I tried the approach used in this answer: Django 1.4 - Redirect to non-HTTP URLs. This does not solve my problem - I do not actually redirect anywhere, and I do not get the error. The URL in the browser also does not change.

My code is:

class UserPhoneNumberView(FormView):
    form_class = UserPhoneNumberForm
    template_name = "get_user_phonenumber.html"

    def form_valid(self, form):
        phonenumber = self.request.POST.get("mobile_number")
        unique = self.request.POST.get("unique")
        url = "http://example.com/"+unique
        response = HttpResponse("", status=302)
        body = "See this url: "+url
        nonhttp_url = "sms:"+phonenumber+"?body="+body
        response['Location'] = str(nonhttp_url)
        return response

I think you should try the @Selcuk suggestion: return a template from FormView with HTML code similar to:

<html>
  <head>
    <meta http-equiv="refresh" content="0;URL={{ url }}" />
  </head>
  <body>
    <!-- The user will see this when they come back to the browser, 
         and if the SMS app does not open right away -->
    Waiting message 
  </body>
</html>

So your django view will become:

from urllib import quote
from django.shortcuts import render

class UserPhoneNumberView(FormView):
    form_class = UserPhoneNumberForm
    template_name = "get_user_phonenumber.html"

    def form_valid(self, form):
        phonenumber = self.request.POST.get("mobile_number")
        unique = self.request.POST.get("unique")
        url = "http://example.com/"+unique
        body = quote("See this url: "+url)
        nonhttp_url = "sms:"+phonenumber+"?body="+body
        context = {'url': nonhttp_url}
        return render(request, 'theTemplate.html', context)

I just tried on my phone, and redirected it to my SMS application.
