'How to retrieve session data with Flask?

I have flask+wtforms application. I can see in login() user object stored as

  if user:
   if user.verify_password(form.password.data):
    flash('You have been logged in')
    user.logins += 1

    db.session.add(History(user.uid))
    db.session.commit()

    session['user'] = user

Now I wanted to retrieve the user

if 'user' in session:
       User=session.get('user')
       print User.nickname ###<< how to retrieve specific object member?

It fails with message like :

Instance <User at 0x8e5a64c> is not bound to a Session; attribute refresh operation cannot proceed

To see all that is in your session you can print(session). You should get a response like

<SecureCookieSession {'_flashes': [('info', 'Duplication is not allowed ')], 'el1-s': 'Physics', 'el1grade-s': 'B2', 'el2-s': 'E-Maths', 'el2grade-s': 'A1', 'english-s': 'A1', 'mathematics-s': 'A1', 'science-s': 'A1', 'social-s': None}>
