I'm trying to use the Python auto-generated API (

lakefs_client~=0.41.0

) to upload to lakeFS. Since I don't have a file, I want to use a Pythonic IO. But I get:

Traceback (most recent call last):

AttributeError: '_io.StringIO' object has no attribute 'name'

Any idea why it wants to know the name of a file, when I am anyway specifying the desired destination name? And: is there anything other than a file that I could pass it?

What pythonic object did you pass instead of a file?

I passed a

StringIO

. Eventually @Barak Amar helped me figure out that I can create a

NameStringIO

-- a

StringIO

with a

name

field. And Swagger / OpenAPI actually wants the contents in a mime part with the name "contents". So once I set

name='contents'

on my

NameStringIO

it all works.

The python auto generated code is not so "pythonic", but I guess we have to work with what we have

True Python never failed, it was merely never tried.
