How to create uuid4 file names for images uploaded with Django-CKEeditor?

I want to create random uid file names for images uploaded with the django-ckeditor/uploader.

I've created utils.py in the same folder as settings.py:

import uuid

def get_name_uid():
    ext = filename.split('.')[-1]
    filename = "%s.%s" % (uuid.uuid4(), ext)
    return filename

I would like to add this "random" file name to settings.py:

CKEDITOR_FILENAME_GENERATOR = get_name_uid()

How can I do this? I am not sure how to get the filename that is uploaded in the editor. Should I pass the filename from settings.py to utils.py? Or is there a different way to do this?

Their documentation says the following:

``CKEDITOR_UPLOAD_PATH = "uploads/"``

When using default file system storage, images will be uploaded to "uploads" folder in your MEDIA_ROOT and urls will be created against MEDIA_URL (/media/uploads/image.jpg).

If you want be able for have control for filename generation, you have to add into settings yours custom filename generator.

```
# utils.py

def get_filename(filename):
    return filename.upper()
```

```
# settings.py

CKEDITOR_FILENAME_GENERATOR = 'utils.get_filename'
```

CKEditor has been tested with django FileSystemStorage and S3BotoStorage.
There are issues using S3Storage from django-storages.
