This allowed me to download the file in chunks and save directly to disk and then tell the Django field where I placed it, as you can see here.

Similar to the object-level readonly field from my previous post, there are some cases where we want to exclude certain fields based on what object the user is trying to access. You could overwrite the views
get_serializer method to use a different serializer based on their access, but if nesting serializers is a possiblility this get messy, somewhere in the neighborhood of O(n2). Another option is to modify a serializers
