![]() This essentially means you require the user to be logged out to continue the flow. If the user is not authenticated, they will be allowed to continue with the process they were trying to complete. If the user is authenticated, a message is displayed using the flash function and the user is redirected to the home page using the redirect function from Flask. The code checks whether a user is already logged in. If you notice the register() and login() function in src/accounts/views.py, you'll find the below code in both of them: if current_user.is_authenticated:įlash("You are already registered.", "info") ![]() How to add a new decorator to check if the user is logged out Notice that the is_confirmed field is set to True in this case because you don't want the admin to verify their account. Print(f"Admin with email created successfully!") ![]() Password = getpass.getpass("Enter password: ")Ĭonfirm_password = getpass.getpass("Enter password again: ") Next, in the manage.py file, update the create_admin command to take the new database fields into account: create_admin(): To migrate and apply these changes in the database, run the following commands: flask db migrate The confirmed_on is a datetime field for the time when the user's email was confirmed, set as nullable. The is_confirmed is a boolean field to indicate whether the user's email address has been confirmed, set as not nullable and defaulting to False. Self.password = bcrypt.generate_password_hash(password) Self, email, password, is_admin=False, is_confirmed=False, confirmed_on=None Is_confirmed = db.Column(db.Boolean, nullable=False, default=False)Ĭonfirmed_on = db.Column(db.DateTime, nullable=True) Is_admin = db.Column(db.Boolean, nullable=False, default=False) Password = db.Column(db.String, nullable=False)Ĭreated_on = db.Column(db.DateTime, nullable=False) Id = db.Column(db.Integer, primary_key=True)Įmail = db.Column(db.String, unique=True, nullable=False) Open the src/accounts/models.py file and update the User class with the following: class User(UserMixin, db.Model): Modelsįirst of all, you'll need to add two new fields – is_confirmed and confirmed_on in the User model of your app. In this section, you will modify the existing implementation of user authentication in our Flask app. This will give you a better understanding of how the user authentication is implemented. You will notice that after completing the registration, the app will automatically log you in and redirect you to the main page.īefore proceeding, I'd recommend exploring the app and then reviewing the code, particularly the accounts blueprint. Once the app is running, go to to register a new user. Run the following command to run the Flask server: python manage.py run ![]() ![]() Run the following commands to set up the database: flask db init Run the following command to export all the environment variables from the. env in the root directory and add the following content there: export SECRET_KEY=fdkjshfhjsdfdskfdsfdcbsjdkfdsdfĮxport APP_SETTINGS=config.DevelopmentConfig After creating and activating a virtual environment, run the following command to install all the dependencies: $ pip install -r requirements.txtĬreate a file named. You can get the code from this repository. To begin, you will use a Flask boilerplate that includes basic user authentication. Feel free to check it out whenever you're stuck. The link to the GitHub repository is available at the end of the tutorial. ![]()
