Django ModelForm ImageField

Question

I have a model and a form (forms.ModelForm) in which I have an ImageField. The model resembles:

class Business(models.Model):
    business_name = models.Char

Here is my solution to the same problem.

from django.utils.safestring import mark_safe
from django.utils.html import escape, conditional_escape
from django.utils.encoding import force_unicode
from django.forms.widgets import ClearableFileInput, Input, CheckboxInput

class CustomClearableFileInput(ClearableFileInput):

    def render(self, name, value, attrs=None):
        substitutions = {
            #uncomment to get 'Currently'
            'initial_text': "", # self.initial_text, 
            'input_text': self.input_text,
            'clear_template': '',
            'clear_checkbox_label': self.clear_checkbox_label,
            }
        template = '%(input)s'
        substitutions['input'] = Input.render(self, name, value, attrs)

        if value and hasattr(value, "url"):
            template = self.template_with_initial
            substitutions['initial'] = (''
                                        % (escape(value.url),
                                           escape(force_unicode(value))))
            if not self.is_required:
                checkbox_name = self.clear_checkbox_name(name)
                checkbox_id = self.clear_checkbox_id(checkbox_name)
                substitutions['clear_checkbox_name'] = conditional_escape(checkbox_name)
                substitutions['clear_checkbox_id'] = conditional_escape(checkbox_id)
                substitutions['clear'] = CheckboxInput().render(checkbox_name, False, attrs={'id': checkbox_id})
                substitutions['clear_template'] = self.template_with_clear % substitutions

        return mark_safe(template % substitutions)

and then just use the extended widget:

business_image = forms.ImageField(widget=CustomClearableFileInput())
