[FIXED] why flask_login does not store authentication in my program?

Issue

i am programming by flask and i have a problem with flask_login login and authentication will complete when i enter username and password and i can get my user data in login page but after redirecting to other pages the user become anonymous! it seems that flask_login or UserMixin module does not work correctly. Please help me to solve this problem in my code

    app = Flask(__name__)
app.secret_key = os.urandom(12)

login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = 'login'



@app.before_request
def before_request():
    g.db = Models.DATABASE
    g.db.connect()
    g.user=current_user

@login_manager.user_loader
def load_user(useremail):
    try:
        return Models.User.select().where(
            Models.User.email == str(useremail)
        ).get()
    except  Models.DoesNotExist:
        return None
@app.after_request
def after_request(response):
g.db.close()
return response

@app.route('/login', methods=('GET','POST'))
def login():

form=forms.Signinform()
if form.validate_on_submit():
    try:
        user = Models.User.get(
            Models.User.email == form.email.data
        )
        if (user.password==hashmypassword(form.password.data)):
            login_user(user)
            flash("You're now logged in!")
            print(user.join_date)
            return redirect(url_for('home'))
        else:
            
            flash("No user with that email/password combo")
            print(hashmypassword(form.password.data))
            print(form.password.data)
            return redirect(url_for('register'))
    except Models.DoesNotExist:
          
          flash("No user with that email/password combo")
    except:
        print(user.password)
        flash ("incorrect")
        
return render_template('login.html',form=form)

@app.route('/')
@app.route('/home')
def home():

if current_user.is_authenticated:
    print(current_user.email)
else:
    print("No AAA")
"""Renders the home page."""
return render_template(
    'index.html',
    title='Home Page',
    year=datetime.datetime.now().year,
)

i am authenticated in login page but not authenticated in home page!

Solution

my problem solved using these functions in my Model class

def is_active(self):
    """True, as all users are active."""
    return True

def get_id(self):
    """Return the email address to satisfy Flask-Login's requirements."""
    return self.email

def is_authenticated(self):
    """Return True if the user is authenticated."""
    return self.authenticated

def is_anonymous(self):
    """False, as anonymous users aren't supported."""
    return False

i thought that def is_authenticated(self) is enough but all of these functions was necessary
