Answer 1

I found a tricky solution :
i replaced the
<div class="form-group">
{{form.photo}}
</div>
in my html file by an input type file <input type="file" name="photo" accept="image/*" id="id_photo"> and i edited my views
views.py
class ProductUpdateView(RedirectToPreviousMixin, UpdateView):
model = Product
form_class = ProductUpdateForm
template_name = 'admin/product_update.html'
def get_object(self):
return Product.objects.get(name=self.kwargs['product_name'])
def form_valid(self, form):
form = form.save(commit=False)
self.photo = form.photo
form.save()
return HttpResponseRedirect(self.get_success_url())
