Comparing date field in a form with current date - django

Question

I am trying to check with an if statement if the date entered in a form is before the current date. If so write to an object in the model. I am also not sure if there are a better way of doing this.
I get this error
'<' not supported between instances of 'DateField' and 'datetime.date'
My view:
class ActionCreateView(LoginRequiredMixin, generic.CreateView):
login_url = '/scrty/login/'
template_name = "nodiso/actioncreate.html"
form_class = forms.LeadActionCreateForm
# success_url = reverse_lazy('nodisoapp:leaddetail', kwargs['pk'] )
def get_success_url(self, **kwargs):
return reverse("nodisoapp:leaddetail", kwargs={'pk':
self.kwargs['pk']})
def form_valid(self, form):
if form.fields['Duedate'] < datetime.date.today():
self.object.overdue = 1
else:
pass
self.object = form.save(commit=False)
self.object.lead_id = self.kwargs['pk']
self.object.creator = self.request.user.firstname
self.object.save()
return super(ActionCreateView, self).form_valid(form)
The Model:
class LeadActions(models.Model):
lead = models.ForeignKey(Leads)
name = models.CharField(max_length=265)
crdate = models.DateField(auto_now_add=True)
Duedate = models.DateField()
creator = models.CharField(max_length=265)
overdue = models.IntegerField(null=True,blank=True)
def __str__(self):
return self.name
The form:
class LeadActionCreateForm(forms.ModelForm):
class Meta:
model = models.LeadActions
fields = ['name','Duedate']

Since you already pull out the unsaved model from the form here:
self.object = form.save(commit=False)
Why not read the Duedate directly from the model instance, and set the overdue flag accordingly ?
is_overdue = self.object.Duedate > datetime.date.today()
self.object.overdue = 1 if is_overdue else None
Complete code:
class ActionCreateView(LoginRequiredMixin, generic.CreateView):
login_url = '/scrty/login/'
template_name = "nodiso/actioncreate.html"
form_class = forms.LeadActionCreateForm
# success_url = reverse_lazy('nodisoapp:leaddetail', kwargs['pk'] )
def get_success_url(self, **kwargs):
return reverse("nodisoapp:leaddetail", kwargs={'pk': self.kwargs['pk']})
def form_valid(self, form):
self.object = form.save(commit=False)
is_overdue = self.object.Duedate > datetime.date.today()
self.object.overdue = 1 if is_overdue else None
self.object.lead_id = self.kwargs['pk']
self.object.creator = self.request.user.firstname
self.object.save()
return super(ActionCreateView, self).form_valid(form)
