[Fixed]-Delete a Picture & thumbnails with sorl.thumbnail (Django)

It seems that you are trying to use the delete method from sorl to delete an instance of the Picture model instead of the picture itself.

This code should work :

from sorl.thumbnail import delete

def deletepicnthumbs(request, pk):
    pictodelete = Picture.objects.get_object_or_404(id=pk, user=request.user)
    # Delete the thumbnails, as well as the original image
    # If you want to keep the original image, pass ```delete_file=False```
    delete(pictodelete.file)
    # We use Django's method to delete the Picture instance, if needed
    pictodelete.delete()
    return redirect(adddetails)

Hope this helps,
Adela
