Only if you don't care of lost files in your upload :-). Here's the code
that I use in my project to handle this. The function receives list of
file fields excludes them from saving by manipulator and handles deletes
and overrides manually. It assumes that file should be deleted if its
associated field in POST is empty.
def process_file_post(manipulator,request,field_names):
data=request.POST.copy()
# file data is not included in data for manipulator.save because
# Django can't handle file deletes and overrides
validation_data=data.copy()
validation_data.update(request.FILES.copy())
errors=manipulator.get_validation_errors(validation_data)
manipulator.do_html2python(data)
if errors:
raise EManipulatorErrors, (errors,data)
for field_name in field_names:
old_filename=getattr(manipulator.original_object,field_name) and
getattr(manipulator.original_object,'get_%s_filename'%field_name)()
obj=manipulator.save(data)
file_field=request.FILES.get('%s_file'%field_name,'')
if (not data[field_name] or file_field) and old_filename:
os.remove(old_filename)
if file_field:
getattr(obj,'save_%s_file'%field_name)(file_field['filename'],file_field['content'])
return obj
