django-file-resubmit - opensource приложение для Django
In Django project you have forms with FileField, ImageField. Everything works great, but when ValidationError is raised, you have to reselect all files and images again. It is kind of annoying. django-file-resubmit solves this problem. It works with FileField, ImageField and sorl.thumbnail.ImageField.
The original idea was developed by team of https://github.com/generalov/django-resubmit. django-file-resubmit was started to avoid some restrictions of django-resubmit, such as supporting last version of sorl-thumbnail, simplify configuration and integration with a project.
