flask-login can not be used in Blueprint object?
blueprint, flask, flask-login
Solution
That's why it called `setup_app`
Just move initialization to your `run.py` and pass app as parameter And login itself can stay inside admin blueprint
Problem
I have a question regarding flask-login and blueprint. admin.py ``` admin = Blueprint('admin', __name__) login_manager = LoginManager() login_manager.setup_app(admin) @login_manager.user_loader def load_user(userid): return User.query.get(int(userid)) @admin.route('/login', methods=["GET", "POST"]) def login(): login_form = LoginForm() if request.method == 'POST': #####user validation#### login_user(user) return redirect('/') return render_template('admin/login.html', login_form=login_form) ``` run.py ``` app = Flask(__name__) app.config.from_object(blog_config) app.register_blueprint(admin) if __name__ == "__main__": app.run(debug=True) ``` But when I post a form, and use login_user(user), an error occurred. ``` AttributeError: 'Flask' object has no attribute 'login_manager' ``` Then I try to use flask-login in run.py, It works fine. run.py ``` login_manager = LoginManager() login_manager.setup_app(admin) @login_manager.user_loader def load_user(userid): return User.query.get(int(userid)) ``` So, What I want to ask is,flask-login can not be used in Blueprint object? THX!
