`size_field` must work same as `ImageField.width_field`, but for file size
in bytes. It may be helpful in systems which use remote storages. For
example, S3 storage from django-storages makes HEAD request for every
`file.size` call. It's painful sometimes.

Comment:
Thanks for this report, however this looks like sth that should be fixed
in `django-storages`. I don't see many use cases for this feature. You can
always add a `@cached_property` to your model to avoid multiple calls of
`FileField.size`, e.g.
{{{
@cached_property
def file_size(self):
return self.file.size
}}}
You can also create a custom field:
{{{
class MyFileField(FileField):
@cached_property
def custom_size_attribute(self):
return self.size
}}}
