Django RESTful Web Services

By: Gaston C. Hillar

Overview of this book

Django is a Python web framework that makes the web development process very easy. It reduces the amount of trivial code, which simplifies the creation of web applications and results in faster development. It is very powerful and a great choice for creating RESTful web services. If you are a Python developer and want to efficiently create RESTful web services with Django for your apps, then this is the right book for you. The book starts off by showing you how to install and configure the environment, required software, and tools to create RESTful web services with Django and the Django REST framework. We then move on to working with advanced serialization and migrations to interact with SQLite and non-SQL data sources. We will use the features included in the Django REST framework to improve our simple web service. Further, we will create API views to process diverse HTTP requests on objects, go through relationships and hyperlinked API management, and then discover the necessary steps to include security and permissions related to data models and APIs. We will also apply throttling rules and run tests to check that versioning works as expected. Next we will run automated tests to improve code coverage. By the end of the book, you will be able to build RESTful web services with Django.

Adding filtering, searching, and ordering

Now, we will add the necessary code to configure the fields that we want to be included in the filtering, searching, and ordering features for each of the class-based views that retrieve the contents of each resource collection. Hence, we will make changes to all the classes with the List suffix in the file: DroneCategoryList, DroneList, PilotList, and CompetitionList.

We will declare the following three class attributes in each of those classes:

  • filter_fields: This attribute specifies a tuple of strings whose values indicate the field names that we want to be able to filter against. Under the hood, the Django REST framework will automatically create a rest_framework.filters.FilterSet class and associate it to the class-based view in which we are declaring the attribute. We will be able to filter against the field names included in the tuple of strings.
  • search_fields: This attribute specifies a tuple of strings whose values indicate the text...
