The login and registration views will create our form objects and pass them to the templates. After the LoginForm validates the user's credentials, we will use Flask-Login to actually log the user in.
In the auth/controllers.py controller, we will find the login view, as shown in the following code:
...from flask_login import login_user, logout_user...@auth_blueprint.route('/login', methods=['GET', 'POST'])@oid.loginhandlerdef login(): form = LoginForm() ... if form.validate_on_submit(): user = User.query.filter_by(username=form.username.data).one() login_user(user, remember=form.remember.data) ... flash("You have been logged in.", category="success") return redirect(url_for('main.index')) ... return render_template('login.html' ...
