I am trying a tutorial from https://www.digitalocean.com/community/tutorials/how-to-add-authentication-to-your-app-with-flask-login.
...
from flask_login import LoginManager
def create_app():
...
db.init_app(app)
login_manager = LoginManager()
login_manager.login_view = 'auth.login'
login_manager.init_app(app)
from .models import User
@login_manager.user_loader
def load_user(user_id):
# since the user_id is just the primary key of our user table, use it in the query for the user
return User.query.get(int(user_id))
However, when I am trying to do from flask_login import LoginManager
I received the error ImportError: cannot import name 'LoginManager' from 'flask_login'
Edit: I have installed flask_login through pip3 both inside and outside of my virtual environment. However, I am unable to use anything from flask_login. I have tried 'from flask_login import UserMixin' as well and a similar error is produced. I have also checked if flask_login is being installed by doing 'pip3 list' and Flask-Login is found in this list too.
May I ask how can I solve this problem? Thank you in advance!
Solved: I made a stupid mistake of not realizing the error is pointing to files in another directory.
pip install flask-login
