Flask Framework Cookbook - Second Edition

Implementing URL routing and product-based pagination

At times, we may encounter a problem where we have to parse the various parts of a URL differently. For example, our URL can have an integer part, a string part, a string part of a specific length, and slashes in the URL. We can parse all these combinations in our URLs using URL converters. In this recipe, we will see how to do this. Also, we will learn how to implement pagination using the Flask-SQLAlchemy extension.
