I have a model form that I use to update a model.

class Turtle(models.Model):
    name = models.CharField(max_length=50, blank=False)
    description = models.TextField(blank=True)

class TurtleForm(forms.ModelForm):
    class Meta:
        model = Turtle

Sometimes I don't need to update the entire model, but only want to update one of the fields. So when I POST the form only has information for the description. When I do that the model never saves because it thinks that the name is being blanked out while my intent is that the name not change and just be used from the model.

    turtle_form = TurtleForm(request.POST, instance=object)
    if turtle_form.is_valid():
        turtle_form.save()

Is there any way to make this happen? Thanks!
