####### here is the view: 



@login_required
def add_job(request):
    form = JobForm(request.POST or None)
    if form.is_valid():
        article = form.save(commit=False)          #####<<<== this is line 19 in the view file. 
        article.author = request.user
        article.save(request.user)
        msg = "Job saved successfully"
        messages.success(request, msg, fail_silently=True)
        return redirect(article)
    return render_to_response('job/job_form.html',
                              { 'form': form },
                              context_instance=RequestContext(request))

### the definition of Jobform in turn is :

class JobForm(forms.ModelForm):
    """ this handles the start_time and end_time defaults"""
    class Meta:
        exclude = ['slug','author',]
        model = Job

    def __init__(self, *args, **kw):
        super(JobForm,self).__init__( *args, **kw)

    def save(self,user, *args, **kw):
        instance = super(JobForm,self).save(commit=False)
        #last_entry = Job.objects.filter(user__id=user.id).order_by('-id')[0] 
        last_entry = Job.objects.filter(user=user).aggregate(max_end_time=models.Max('end_time'))['max_end_time']
        if last_entry:
            instance.start_time = last_entry.end_time
        else:
            # this is the very first record do something
            pass
        instance.save()
        return instance
