Django storages backend url pattern error when using dropbox

Question

I am trying to use dropbox as a backend storage solution for django using django-storages, i followed the documentation but i am getting this error:

'C:/media/post_pics/profile_pic.jpeg' did not match pattern '(/(.|[\r\n])*|id:.*)|(rev:[0-9a-f]{9,})|(ns:[0-9]+(/.*)?)'

This is my models.py:

class Post(models.Model):
    title = models.CharField(max_length=64)
    date = models.DateField(timezone.now())
    picture = models.ImageField(upload_to='post_pics') 

...and my settings.py:

STATIC_URL = '/static/'

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

# Dropbox media file storage

DEFAULT_FILE_STORAGE = 'storages.backends.dropbox.DropBoxStorage'
DROPBOX_OAUTH2_TOKEN = 'myToken'
DROPBOX_ROOT_PATH = '/media/'

Answer 1

It turns out it was just a problem with how windows path works, using a linux system solved it
