Session

Using Streamlit
, ,
1

Hi all,
I need to ensure that, when I click on the “Reports” or “Analysis” button, the information previously selected in the “document_options” variable no longer appears on the screen. I have already tried using “del session_state” when clicking on one of the buttons, but it doesn’t work. anyone here to help me?

import streamlit as st 

def list_docs():
    st.title("Test")
    st.write("") 
    if "selected_option_case" not in st.session_state:
        st.session_state.selected_option_case = None 

    if "selected_document_prev" not in st.session_state:
        st.session_state.selected_document_prev = None   
    
    case_options = ["0001", "0002", "0003", "0004"]
    selected_case = st.selectbox("**Select a case**", case_options, key="selected_option_case") 
    
    if selected_case:   
        st.success(f"You selected: {selected_case}")   
        col_1, col_2, col_3, col_4, col_5, col_6, col_7, col_8 = st.columns([2.3, 0.3, 2.3, 0.3, 2.3, 0.3, 2.3, 4.9]) 
        
        if col_1.button("Original documents", key="view_document", use_container_width=True) or st.session_state.selected_document_prev:  
            document_options = ["document 0001.pdf", "test.mp4", "output_audio.wav", "Prop.pdf"]
            selected_document = st.selectbox(
                "**Select a document**", 
                document_options, 
                key="selected_document_prev")

            if selected_document: 
                st.success(f"You selected: {selected_document}")  # Debugging: show selected document
        
        if col_3.button("Reports", key="update_lists", use_container_width=True): 
            if 'selected_document_prev' in st.session_state:
                del st.session_state.selected_document_prev  # Remove document selection when 'Reports' is clicked
            st.write("**Summary**") 
            pdf_text = """Noii."""  
            st.text_area(" ", pdf_text, height=300, key="Summary-Text")  

        if col_5.button("Analysis", key="tests-stage", use_container_width=True):
            if 'selected_document_prev' in st.session_state:
                del st.session_state.selected_document_prev  # Remove document selection when 'Analysis' is clicked
            st.write("**Conv**") 
            pdf_text = """ ....."""  
            st.text_area(" ", pdf_text, height=300, key="Convergences-Text")

You can use on_click :

 def reset_selection():
     st.session_state.show_document_selection = False
 st.title("Test")
        st.write("")

        if "selected_option_case" not in st.session_state:
            st.session_state.selected_option_case = None

        if "selected_document_prev" not in st.session_state:
            st.session_state.selected_document_prev = None

        if "show_document_selection" not in st.session_state:
            st.session_state.show_document_selection = False

        case_options = ["0001", "0002", "0003", "0004"]
        selected_case = st.selectbox("**Select a case**", case_options, key="selected_option_case")

        if selected_case:
            st.success(f"You selected: {selected_case}")
            col_1, col_2, col_3, col_4, col_5, col_6, col_7, col_8 = st.columns(
                [2.3, 0.3, 2.3, 0.3, 2.3, 0.3, 2.3, 4.9])

            if col_1.button("Original documents", key="view_document", use_container_width=True):
                st.session_state.show_document_selection = True


            if st.session_state.show_document_selection:
                document_options = ["document 0001.pdf", "test.mp4", "output_audio.wav", "Prop.pdf"]
                selected_document = st.selectbox(
                    "**Select a document**",
                    document_options,
                    key="selected_document_prev")

                if selected_document:
                    st.success(f"You selected: {selected_document}")



            if col_3.button("Reports", key="update_lists", use_container_width=True, on_click=reset_selection):
                st.write("**Summary**")
                pdf_text = """Noii."""
                st.text_area(" ", pdf_text, height=300, key="Summary-Text")

            if col_5.button("Analysis", key="tests-stage", use_container_width=True,on_click=reset_selection):
                st.session_state.show_document_selection = False
                st.write("**Conv**")
                pdf_text = """ ....."""
                st.text_area(" ", pdf_text, height=300, key="Convergences-Text")

It worked with the on_click function. Thank you
