We will get more practice in writing validators.
- [Instructor] In the last video,…we implemented some useful form validation.…Let's add two more in this video.…We used the DataRequired validator to make sure…that each field was filled out.…So what else should we validate?…We should probably make sure that…the info entered in the email field…is actually an email address.…We can do this with the Email validator.…Let's follow the same steps as we did…with the DataRequired validator.…Open up Forms.py and import the Email validator.…
Then, go to the email field, and…append the Email validator to the validators list.…Give a useful error message here inside the parenthesis.…Let's see if this works.…Visit the sign up page again.…Enter an invalid email and click Sign Up.…And there's the error message.…The Email validator is working as expected.…Now, what else can we validate?…We should probably make sure that…the password is longer than six characters.…
We don't want short, insecure passwords.…So let's implement this.…We can do this with the Length validator.…Open up the Forms.py again and import the Length validator.…
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.
