how can my view return response performing the some function parrallely
===

views.py


    from registration.models import Registration
    from django.core.context_processors import csrf
    from registration import tasks
    from django.shortcuts import render_to_response
    def validate(request):
        state="notvalid"
        if request.method == 'POST':# If the form has been submitted...
            form = Registration(request.POST) # A form bound to the POST data
            state="notvalid"
            if form.is_valid(): 
                username = form.cleaned_data['username']
                first_name = form.cleaned_data['first_name']
                last_name = form.cleaned_data['last_name']
                email = form.cleaned_data['email']
                password = form.cleaned_data['password']
                from django.contrib.auth.models import User
                user = User.objects.create_user(username,email,password)
                user.first_name=first_name
                user.last_name=last_name		
                user.save()	
                state="added data"
            tasks.mail()
        else:
            form = Registration() # An unbound form
    
        return render_to_response('auth1.html', {
            'form': form,'state':state,
        })

tasks.py

    from celery import task
    import celery
    
    @celery.task()
    def mail():
        from django.core.mail import send_mail
        for x in range(10000000):
            print x
        return True


the task has to be performed parrelel without affecting the time of views response. I.e
in background it has to run mail function

but after database adding it hase to return render_to_response
