Creating a User model to communicate with the "users" table.
- [Instructor] What have we done so far?…First, inside the learning class database,…we created a users table to store user information.…Second, we used Flask-SQLAlchemy…to connect Flask to this database.…The last thing we need is a data structure…that we can use from the app…to read and write to the users table.…This data structure is called a model.…We will write this code in a new file called models.py.…This way, the model stays separate…from the code in routes.py,…which maps URLs to functions.…
So, make a new file called models.py.…Open models.py in the text editor,…and add the following code.…Let's go through this code line by line.…In line one, we import…the SQLAlchemy class from Flask-SQLAlchemy.…Then, in line four, we create a variable named db…containing a new usable instance of the SQLAlchemy class.…Then, in lines six through 12,…we create a Python class to model the user's attributes.…These are the same as the columns for the user table,…so uid, firstname, lastname, email, and pwdhash.…
In lines 14 through 18, we create a constructor…
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.
