Streamlit 1.36.0 breaks functionality

[danb27]

To reproduce:

# ui.py
from st_pages import Page, show_pages

pages = [
    Page("ui.py", "home"),
    Page("page.py", "page"),
]
show_pages(pages)

# page.py
import streamlit as st

st.title("hi")

# requirements.txt
streamlit==1.36.0
st_pages==0.4.5

streamlit run ui.py

Results in exception:

AttributeError: 'str' object has no attribute 'main_script_path'
Traceback:

Temporary fix is to set streamlit<1.36.0 in your application

Just found out that Streamlit 1.36.0 introduced st.navigation and st.Page. Maybe now Streamlit officially supports this feature and this 3rd party is not necessary anymore?

Ooo interesting. I was just focused on fixing my build.

FWIW, I'm still interested in solving this within st_pages because the new functionality mentioned by @george-gca does not allow for multiprocessing to be run in the app (as far as I can tell).

@blackary, any ideas? Thanks in advance!

[HoangNguyen689]

I am still facing this problem with show_pages_from_config(). Do you fix that in v0.5.0?

[blackary]

Yes, this should be fixed by release 0.5.0

[andrew-weisman]

Confirmed that 0.5.0 fixes the problem. Thanks so much @blackary!
