✅

You can make your own FileField and then work with that instead, so:

from rest_framework.fields import FileField
from rest_framework.settings import api_settings

class FileWithoutHostField(FileField):
    def to_representation(self, value):
        if not value:
            return None

        use_url = getattr(self, 'use_url', api_settings.UPLOADED_FILES_USE_URL)
        if use_url:
            try:
                return value.url
            except AttributeError:
                return None
        return value.name

You can now inject the FileWithoutHostField in the serializer_field_mapping [drf-doc] to use this instead of the FileField, so:

from django.db.models import fields
from django_rest.serializers import ModelSerializer

ModelSerializer.serializer_field_mapping[fields.FileField] = FileWithoutHostField
