Django-filer get absolute URL and Django Celery Upload

Question

Is it possible to get the absolute URL of a file just uploaded with Django Filer?

My problem is this:

I'm using Django Filer to upload music. I then want to submit this file to Django Celery to upload to Mixcloud using their API. But..

I can't figure out how to get URL of the file. I'm not using views, I want to just use the admin, grab the file just uploaded and send to Celery to upload to Mixcloud using their API. But i can only import the object from the model to celery.

My Model:

class MixcloudUpload(models.Model):
    files = FilerFileField(null=True, blank=True)
    data = {'name': 'API Test'}


    def save(self, *args, **kwargs):

        super(MixcloudUpload, self).save(*args, **kwargs)
        from .tasks import uploadtask
        uploadtask.delay(self.id)

My Task:

@celery_app.task()
def uploadtask(request):
    sleep(5)
    # Update the state. The meta data is available in task.info dicttionary
    # The meta data is useful to store relevant information to the task
    # Here we are storing the upload progress in the meta.
    post_url = 'https://api.mixcloud.com/upload/?access_token=ugY'
    from .models import MixcloudUpload
    mp3 = MixcloudUpload.files
    data = MixcloudUpload.data
    files = ({'mp3': open(mp3)})
    headers = {'enctype': 'multipart/form-data'}
    r = requests.post(post_url, headers=headers, files=files, data=data, verify=True)
    return r, r.json(), request

Django Filer sets the uploaded_at (datetime field) model attribute on upload. You can filter on this to get new uploads to forward to Mixcloud.

As for getting the absolute url. The filer documentation is a bit tricky in this respect. But there are two attributes which you can use:

• File.objects.all()[0].path, is the path to the file on the filesystem.
• File.objects.all()[0].url, the url path after the domain, e.g.: /media/filer_public/23/23/34565b67-e1de-41da-3132-1403c335fdd4/test_img.png/. You need to prepend your domain yourself. So the full path would be something like: "http" + urlencode(site_obj.domain) + filer_obj.url.
