How to assign currently logged in user as default value for a model field?

Question

I\'d like to do something like this:

class Task(models.Model):
    ...
    created_by = models.ForeignKey(User, **default=[LoggedInUser]** blank=True, null=T

If use ModelForm, the following will fill a default value for a special field. such as, owner filed is a charfield for user's name

def fillview(request):
    instance = YourModel(owner=request.user.username)
    form = YourModelForm(instance=instance)

    if request.method == 'POST':
        form = YourModelForm(request.POST, request.FILES)
        if form.is_valid():
            pass
            return render(request, 'success.html')

    return render(request, 'fill.html', {'form': form})

When logged in, you could see owner filed is current user's name.
