One abstract method is a method that is declared, but contains no implementation. Abstract classes cannot be instantiated, and require subclasses to provide implementations for the abstract methods. It's kinda like Interfaces in Java. Even if the methods don't implements anything, the child classes should implemente those methods.
Different thant an abstract method, a concret method does implement something even the class is an Abstract Class
Web server gateway interface From Wikpedia: Is a simple calling convention for web servers to forward requests to web applications or frameworks written in Python. Originally specified as PEP-333
It is a file that we can barely write. Or need to.
Is a web server that communicates with out application and handle all requests and responses. The django project need it, to work as a web application.
In this gist, I will show the difference between three ways to build endpoints with Django Rest Framework. The pros and cons of each one, when you should use it and so on.
A REST framework provides an APIView class, which subclasses Django's View class.
According to the docs, the View class is a callable which takes a request and returns a response. Is more than the view function because we can wrappe better the request-response flow, following REST principles
| import json | |
| import requests | |
| def save_file(file_name, data): | |
| with open(file_name, 'w') as file: | |
| json_data = json.dumps(data) | |
| file.write(json_data) | |
| def fetch_json(url, headers={}): | |
| response = requests.get(url, headers=headers) |
