How to exclude django form field from render but still keep it for validation?

Question

If I have a model (extract):

class Coupon(models.Model):
    image = models.ImageField(max_length=64, null=True, upload_to=\"couponimages\")

I think the best way to achieve that is to create a widget that renders nothing:

class NoInput(forms.Widget):
    input_type = "hidden"
    template_name = ""

    def render(self, name, value, attrs=None, renderer=None):
        return ""

class YourForm(forms.Form):
    control = forms.CharField(required=False, widget=NoInput)

This way you can still use {{form}} in your template.
