I have created a simple register and login method using flask with combination of pymongo.
Now for user session management i am using flask_login
but it gives me this error
AttributeError: 'dict' object has no attribute 'is_active'

the solution that i found different post was to add UserMaxIn in UserClass
but i dont have any class for User Model and i dont want to make it either

what would be the solution of this error ?

Flask-Login requires that you use a class to represent users, not a raw dict.

As described in documentation, this class needs to implement some properties and methods, included the is_active() method.

The UserMixin class is the base class that provides default implementations for all the required properties and methods and you can extend it and create a simple User class.

Update: added example

Based on what you already have, the simplest thing you can do is:

create a custom User class that extends UserMixin

store the json object from MongoDB inside the User class

override the methods for which you require a behavior different from the default one

In the /login route create an instance of the User class and pass it to flask_login.login_user()

User class

class User(UserMixin):

    def __init__(self, user_json):

        self.user_json = user_json



    # Overriding get_id is required if you don't have the id property

    # Check the source code for UserMixin for details

    def get_id(self):

        object_id = self.user_json.get('_id')

        return str(object_id)

For all the methods/properties (is_authenticated, is_active, is_anonymous), except get_id it uses the default implementations. If you don't need the default implementations you don't need to extend UserMixin but you have to implement all the methods by yourself.

Usage of the User class in login route

@app.route("/login", methods=['GET', 'POST'])

def login():

    form = LoginForm()

    if form.validate_on_submit():

        users = mongo.db.users

        loginuser_json = users.find_one({'email': form.email.data})

        if loginuser_json and bcrypt.check_password_hash(loginuser_json['password'], form.password.data):

            # Create a custom user and pass it to login_user:

            loginuser = User(loginuser_json)

            login_user(loginuser, remember=form.data.remember)

            return redirect(url_for('home'))

        else:

            flash('Login Unsuccessful. Please check username and password', 'danger')

    return render_template('login.html', title='Login', form=form)

Remember that you also have to provide a user_loader as described here. For example, given the user_id, perform a query on MongoDB and return the User object:

@login_manager.user_loader

def load_user(user_id):

    users = mongo.db.users

    user_json = users.find_one({'_id': ObjectId(user_id)})

    return User(user_json)

You can get it from the json object: loginuser_json.get('email'). If you want to get it from a User object: user_object.user_json.get('email') or you can add a new method get_email inside the User class.

            login_user(loginuser, remember=form.data.remember)

            return redirect(url_for('home'))

        else:

            flash('Login Unsuccessful. Please check username and password', 'danger')

    return render_template('login.html', title='Login', form=form)

Remember that you also have to provide a user_loader as described here. For example, given the user_id, perform a query on MongoDB and return the User object:

@login_manager.user_loader

def load_user(user_id):

    users = mongo.db.users

    user_json = users.find_one({'_id': ObjectId(user_id)})

    return User(user_json)

You can get it from the json object: loginuser_json.get('email'). If you want to get it from a User object: user_object.user_json.get('email') or you can add a new method get_email inside the User class.
