Summary
I tried to create a login register system for my streamlit app but I have hard time to hide pages and show them after registering or logining.
I tried solution here but didn’t worked for me: example
Steps to reproduce
Code
import streamlit as st
import pymongo
import bcrypt
def get_database():
client = pymongo.MongoClient()
return client['db']
dbname = get_database()
users = dbname["users"]
def register(username, email, password):
# Hash the password
hashed_password = bcrypt.hashpw(password.encode('utf-8'), bcrypt.gensalt())
# Check if the username already exists in the users collection
existing_user = users.find_one({"username": username})
if existing_user:
return False
else:
# Insert user data into the users collection
users.insert_one({
"username": username,
"email": email,
"password": hashed_password.decode()
})
return True
def login(username, password):
# Check if the user exists in the users collection
user = users.find_one({"username": username})
if user:
# Compare the entered password with the hashed password stored in the database
if bcrypt.checkpw(password.encode('utf-8'), user["password"].encode('utf-8')):
return True
return False
def login_page():
username = st.text_input("Username")
email = st.text_input("Email")
password = st.text_input("Password", type='password')
global is_logged_in
if st.button("Login"):
if login(username, password):
is_logged_in = True
st.success("Logged in!")
else:
st.error("Invalid username or password")
if st.button("Register"):
if register(username, email, password):
is_logged_in = True
st.success("User registered!")
else:
st.error("Username already exists")
def navigation():
st.sidebar.title("Navigation")
is_logged_in = False
if st.button("Home"):
st.write("This is the home page")
if is_logged_in:
pages = ['page1','page2']
for page in pages:
if st.button(page.replace("_"," ").title()):
mod = __import__(f"pages.{page}", fromlist=[page])
func_name = f"{page}_page"
func = getattr(mod, func_name)
func()
if st.button("Logout"):
is_logged_in = False
st.success("Logged out!")
else:
st.warning("Please login to access other pages.")
is_logged_in = False
if not is_logged_in:
st.set_page_config(initial_sidebar_state="collapsed")
login_page()
else:
st.write("Welcome to my App")
st.set_page_config(initial_sidebar_state="expanded")
navigation()
I have pages file which include 2 different python file as page.
I can login and register there is no problem with that.
Expected behavior:
I wanted to pages been seen and used when login or register is successful only and also I wanted to add a logout button make user to return login or register page when pressed.
Actual behavior:
Even the login page opened I can still see pages in left side without actually login or register, I can’t restrict them to be seen before login or register.
