understanding of python

What is a Rest API?
As opposed to a graphQL api rest api have remained the preferred api method. On a basic understanding a rest api a website will send a request to a url for their server. The request will return the data needed.
Using auth services
If you are in a rush to build a project using a auth service such as auth0 it can be more efficient but it is often expensive when you can just build your own auth.

POST Requests
The primary way for websites to send data is through a post request. The website will send a json formatted data to a server url in which the server will handle and return a response accordingly.
Django's built in User Model
Django comes with a built in user model that automatically encodes passwords and handles harder things for you. you can import this from
from django.contrib.authhandling a post request with django
to handle a request you need to create a view and attach a url.
create user example
from django.contrib.auth.models import User
from django.contrib.auth import authenticate
from rest_framework import status
from rest_framework.decorators import api_view
from rest_framework.response import Response
def username_exists(username):
if User.objects.filter(username=username).exists():
return True
return False
@api_view(['POST'])
def createUserView(request):
# response["Access-Control-Allow-Origin"] = "*"
# response["Access-Control-Allow-Methods"] = "POST, OPTIONS"
# response["Access-Control-Max-Age"] = "1000"
# response["Access-Control-Allow-Headers"] = "X-Requested-With, Content-Type"
print(request.user)
username = request.data["username"]
email= request.data["email"]
password = request.data["password"]
if username_exists(username):
return Response("User Exists")
if len(list(username)) < 6:
return Response("Requires Longer Username")
if len(list(password)) < 6:
return Response("Requires Longer Password")
user = User.objects.create_user(
username=username, email=email, password=password)
created_user = user.get_username(user)
return Response(created_user, "account Created")In urls.py
from django.urls import path
urlpatterns = [
path("create", createUserView),
]Now Sending a post request to api/create, this view is attached to will create a user in django if the username and password is longer than 6 characters and no one has that username
From this post request example you can see how to handle a post request a then take action accordingly. from this you can look at django documentation on the functions to login, auth, delete and more. https://docs.djangoproject.com/en/3.1/ref/contrib/auth/
