While trying to add a simple “Attachments” feature to one of my applications I ran across an issue where a record with file could be added from the Django Admin, but would fail with a validation error when used in my forms.
The error came down to my missing something from views.py in the form instantiation from the POST data.
def handle_files(request):
if request.method == 'POST':
form = MyForm(request.POST, request.FILES)
if form.is_valid():
form.save() I was missing the additional parameter for the FILES from the request object. I ran across so many articles that didn’t show THAT, or I was just missing it, that I spent far too long on trying to solve this simple error.
Update: This is covered in the Django documentation, but somehow I managed to over look it every single time I read it.

Hopefully this saves someone the time it took me to resolve this issue.
