django-file-resubmit 0.3.4

Keeps submited files when validation errors occure.

Latest Version: 0.4.1

# django-file-resubmit

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.

## How does it work?

Here are advanced widgets for FileField and ImageField. When you submit files, every widget
saves its file in cache. And when ValidationError is raised, widgets restore files from cache.


# Requirements

 - sorl-thumbnail, http://thumbnail.sorl.net/

# Installation

     $ pip install django-file-resubmit


# Configuration

Add `"file_resubmit"` to `INSTALLED_APPS`.

    INSTALLED_APPS = {
        ...
        'sorl.thumbnail',
        'file_resubmit',
        ...
    }

Setup cache in settings.py.

    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        },
        "file_resubmit": {
            'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache',
            "LOCATION": project_path('data/cache/file_resubmit')
        },
    }

            model = MyModel
            widgets = {
