I just write a flask login demo.
@app.route('/reg/', methods=['GET', 'POST'])
def reg():
username = request.form.get('username').strip()
password = request.form.get('password').strip()
if (username == '' or password == ''):
return redirect_with_msg('/regloginpage/', u'用户名或密码不能为空', category='reglogin')
user = User.query.filter_by(username=username).first()
if (user != None):
return redirect_with_msg('/regloginpage/', u'用户名已存在', category='reglogin')
salt = '.'.join(random.sample('0123456789abcdfeghijklmnABCDEFG', 10))
m = hashlib.md5()
str1 = (password + salt).encode('utf-8')
m.update(str1)
password = m.hexdigest()
user = User(username, password, salt)
db.session.add(user)
db.session.commit()
login_user(user)
return redirect('/')
And Traceback like this:
TypeError: 'int' object is not callable
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/flask/app.py", line 1598, in dispatch_request

user_id = getattr(user, current_app.login_manager.id_attribute)()
TypeError: 'int' object is not callable
It makes me upset, someone can save me ?
I just ran into this same issue with flask-login and landed on this question. While @Sweater-Baron's answer hints at the issue, here's the direct fix in your User class since it doesn't make sense to edit Flask-Login. The method get_id() should not be declared as a property:
@property
def get_id(self):
return self.uid
unlike is_authenticated(), is_active() and is_anonymous().
def get_id(self):
return self.uid
From the Flask-Login documentation:
get_id()
This method must return a unicode that uniquely identifies this user, and can be used to load the user from the user_loader callback.
[emphasis is mine]
Reading the error message shows that the error is occurring on line 140 of utils.py. This is probably because you have
user_id = getattr(user, current_app.login_manager.id_attribute)()
The () on the end is making your program try to call the return value of getattr as a function, when it is an int. Remove the () and it should work.
