Python API Development Fundamentals

By: Jack Chan, Ray Chung, Jack Huang

Overview of this book

Python is a flexible language that can be used for much more than just script development. By knowing the Python RESTful APIs work, you can build a powerful backend for web applications and mobile applications using Python. You'll take your first steps by building a simple API and learning how the frontend web interface can communicate with the backend. You'll also learn how to serialize and deserialize objects using the marshmallow library. Then, you'll learn how to authenticate and authorize users using Flask-JWT. You'll also learn how to enhance your APIs by adding useful features, such as email, image upload, searching, and pagination. You'll wrap up the whole book by deploying your APIs to the cloud. By the end of this book, you'll have the confidence and skill to leverage the power of RESTful APIs and Python to build efficient web applications.

Activity 13: Implementing Pagination on the User-Specific Recipe Retrieval API

Solution

  1. Modify the code in the get_all_by_user method under models/recipe.py, as follows:
        @classmethod
        def get_all_by_user(cls, user_id, page, per_page, visibility='public'):
            query = cls.query.filter_by(user_id=user_id)
            if visibility == 'public':
                query = cls.query.filter_by(user_id=user_id, is_publish=True)
            elif visibility == 'private':
                query = cls.query.filter_by(user_id=user_id, is_publish=False)
            return query.order_by(desc(cls.created_at)).paginate...
