Hello evryone!
I know that streamlitâs multipage app works in a way such that each file in the pages folder will be a page, and thus be rendered in the applicationâs sidebar.
I am trying to make a streamlit application such that when the application is visited, only one page is shown in the sidebar, namely the âSign Inâ page. When successful sign-in, the application should show the other pages in the sidebar and hide the Sign In page.
To do this, I would need to hide/show pages in the sidebar based on certain conditions (in my case, based on whether the user has successfully signed in then will be show all pages ). However, it looks like whatever is in the pages folder WILL be rendered as a page on the sidebar by default, and thereâs no way to customise which pages get rendered when.
Here is the Code of Log In Page
# Setup
import streamlit as st
import pandas as pd
import hashlib
# Convert Pass into hash format
def make_hashes(password):
return hashlib.sha256(str.encode(password)).hexdigest()
# Check password matches during login
def check_hashes(password,hashed_text):
if make_hashes(password) == hashed_text:
return hashed_text
return False
# DB Management
import sqlite3
conn = sqlite3.connect('user_data.db')
c = conn.cursor()
# DB Functions for create table
def create_usertable():
c.execute('CREATE TABLE IF NOT EXISTS userstable(username TEXT,email TEX, password TEXT)')
# Insert the data into table
def add_userdata(username,email,password):
c.execute('INSERT INTO userstable(username,email,password) VALUES (?,?,?)',(username,email,password))
conn.commit()
# Password and email fetch
def login_user(email,password):
c.execute('SELECT * FROM userstable WHERE email =? AND password = ?',(email,password))
data = c.fetchall()
return data
def view_all_users():
c.execute('SELECT * FROM userstable')
data = c.fetchall()
return data
# Mian function
def main():
#"""Login page"""
st.title("welcome! ")
menu = ["Login","SignUp"]
choice = st.selectbox("Select Login or SignUp from dropdown box âž",menu,)
st.markdown(
"<h10 style='text-align: left; color: #ffffff;'> If you do not have an account, create an accouunt by select SignUp option from above dropdown box.</h10>",
unsafe_allow_html=True
)
if choice == "":
st.subheader("Login")
elif choice == 'Login':
st.write('-------')
st.subheader('Log in to the App')
email = st.text_input("User Name",placeholder='email')
password = st.text_input("Password",type='password')
if st.checkbox("Login"):
# if password == '12345':
# Hash password creation and store in a table
create_usertable()
hashed_pswd = make_hashes(password)
result = login_user(email,check_hashes(password,hashed_pswd))
if result:
st.success("Logged In as {}".format(email))
if st.success:
st.subheader("User Profiles")
user_result = view_all_users()
clean_db = pd.DataFrame(user_result,columns=["Username","Email","Password"])
st.dataframe(clean_db)
else:
st.warning("Incorrect Username/Password")
elif choice == "SignUp":
st.write('-----')
st.subheader("Create New Account")
new_user = st.text_input("Username",placeholder='name')
new_user_email = st.text_input('Email id',placeholder='email')
new_password = st.text_input("Password",type='password')
if st.button("Signup"):
if new_user == '': # if user name empty then show the warnings
st.warning('Inavlid user name')
elif new_user_email == '': # if email empty then show the warnings
st.warning('Invalid email id')
elif new_password == '': # if password empty then show the warnings
st.warning('Invalid password')
else:
create_usertable()
add_userdata(new_user,new_user_email,make_hashes(new_password))
st.success("You have successfully created a valid Account")
st.info("Go up and Login to you account")
if __name__ == '__main__':
main()
Expected behavior:
Is there a way to achieve conditional rendering of pages on the sidebar, using Streamlitâs?
