The sign-in form allows users to sign in to the app using their credentials. In this video, we’ll write the sign in form’s bac kend and front end.
- [Instructor] We built…the sign up page in the previous video.…Let's move on to the second topic…and build a login page too.…This is very similar to the sequence…of steps we used to create a sign up page.…So there are three things we need to do here.…First, create a new class named login form in forms.py.…Second, create a new URL mapping for…/login in routes.py.…And third, create a web template…in templates to create this form.…
Let's get started.…Open up forms.py and create a new class named login form.…The login form class will be similar…to the sign up form class we created.…So inherit from the base form class.…There will be two fields in this class…for a user's email and password.…Both fields will have validators on them.…The DataRequired validator checks…that the field contains data.…And the custom error message that it will display is…"Please enter your email address".…
The Email validator will check that the field…looks like an email address.…And its custom error message will say…"Please enter your email address" as well.…
The need for talented developers is greater than ever before. A basic grounding in a framework as simple, powerful, and easy-to-learn as Flask—a Python micro framework—can help launch your programming career. Get a basic grounding in the fundamental concepts of web development, as well as the hands-on experience required to successfully build web apps with Flask, in this course with Packt trainer Lalith Polepeddi.
It starts with turning your computer into a modern development machine. Then learn everything you need to know about Flask: models, views, controllers, web templates, forms, validation, and API interactions. Lalith shows how to apply these concepts and develop a powerful database-backed Flask app, including a full authentication system. Finally, Lalith shows how to extend the app's functionality by integrating it with third-party APIs. When you finish this course, you will be fully equipped to build your very own custom web apps with Flash.
