It resolves user registration, sign in, and sign out, as well as social account integration. You can easily integrate this set of REST API endpoints with your project. In the spirit of don’t reinvent the wheel, you can use an existing customizable solution for session management: Django-rest-auth. Most web applications have users and authentication methods. For a configuration example, read the Django docs. Or you can just explicitly define the desired paths for specific resources. By knowing this, you can change the order of the INSTALLED_APPS according to our needs. If that happens, Django’s default behavior is to first check in the templates folder of the first app in the list. It’s important to take order into account because it’s common for several apps to provide different versions of the same resource as a template or static file. For example, template files can be used by the project frontend or to send emails. They’re great for generating dynamic code in Django. Templatesįinally, let’s talk about templates. With Django, you can also define serializers that aren’t attached to models, nest serializers and relationships between them, and more. You don’t need to make that explicit in the serializer. For example, if the incoming name length is bigger than 50 characters, then the serializer raises an exception, because the maximum length was defined in the model. So by default, it does basic validation related to the model. In the previous example, PersonDetailSerializer is attached to the Person model. In summary, serializers are a good way to validate incoming data. A good way to do that is with validating function: validate(self, data). An example is validating constraints between fields. Sometimes you need to define a more complex validation inside the serializer class. In the PersonDetailSerializer, you can do a field-level validation that just defines a function named validate_. You want to run some checks on them when a new request comes into the REST API. For example, you might have values for the fields of serializers in your web app. The next good practice is how to locate the validation of incoming data. Serializers also cover some issues related to requests and responses, so you don’t have to worry about them. The generic views and serializers aren’t required, but they can simplify a lot of work. You can also use the mixins to redefine the methods and specific functions like create, update, destroy, and others. But what if you want to customize the functions and change the default behavior? You can redefine get, post, put, delete, and other methods. Some examples are CreateAPIView, ListAPIView, RetrieveAPIView, and RetrieveDestroyAPIView. The many generic views in the Django documentation meet a wide range of functionality needs. With Django’s generic views, you only need to define the class view as a child of the generic view, depending on your needs. Some examples of retrieving information, creating, destroying, listing, and updating. The Django REST framework has generic views that perform common tasks related to the model instances. For general design and any bugs you might run into, you could consider the generic tested and maintained solutions, such as Generic views. There are also many ways to implement views and serializers. There are many ways to implement the functionalities of a REST API by using the Django frameworks. They’re made up of some static code and other elements that depend on the context. Templates are files with static and dynamic content. I like to define them as interfaces for the backend of the web app. Serializer classes provide control of data types and structures of requests and responses. You can implement them in many ways, such as functions or classes. Views are in charge of the process of requests. With models, it’s easy to define tables and relationships between them. You can query the databases without any SQL programming. A model is mapped to a table in the database. Model classes provide an object-relational map (ORM) for the underlying database. To work with Django and Django REST, it’s important to grasp these concepts: Understand the main concepts of Django and Django REST If you want to build REST APIs, you can combine Django with the Django REST framework to generate a base project in just a few seconds. It’s fast, secure, scalable, and well documented. You can use them for free on your apps, and you can also make contributions and propose improvements!ĭjango is a solid framework for developing web apps with Python language. There are many open-source projects that perform common tasks to solve general problems. It’s better and faster to take advantage of a known solution than to spend time creating a new one. If you run into a problem when you’re coding that already has a documented solution, don’t reinvent the wheel.
