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
It's simple. If you want to retrieve a specific object simply add the name of the variable within session, e.g. session['nickname']
.
You can set the variable the same way, by doing session['nickname'] = nickname
.
In your case you would change it to the following
if 'user' in session:
user = session['user']
print user
if 'nickname' in session:
nickname = session['nickname']
print nickname
This is an simplified version of the function I use for login.
@app.route('/login', methods=['POST'])
def login():
"""Authenticate User"""
username = request.form['username'].strip()
nickname = request.form['nickname'].strip()
password = request.form['password']
try:
if Auth().VerifyLogin(username, password):
session['username'] = username
session['nickname'] = nickname
else:
# failed to login, do something.
except Exception as why:
app.logger.critical('.....')
