Views ​

Function based views ​

Funksiyaga asoslangan viewni yozish uchun DRFda @api_view dekoratoridan foydalanamiz.

python
from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view()
def example(request):
    text = "This is example for @api_view"
    return Response(text)

Agar viewga murojaat qilinadigan metodlarga cheklov qo'ymoqchi bo'lsak, u holda

python
from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view(['GET', 'POST'])
def example(request):
    text = "This is example for @api_view with methods"
    return Response(text)

Endi viewga faqat GET va POST metodlari orqali murojaat qilish mumkin. Yuqoridagi holatda esa viewga istalgan metod orqali murojaat qilish mumkin.

Class based views ​

Klassga asoslangan viewlarda djangodagi View o'rniga DRFda APIView klassidan foydalanamiz.

python
from rest_framework.response import Response
from rest_framework.views import APIView

class ExampleView(APIView):
    def get(self, request):
        return Response("This is simple class based view example")

Shuningdek DRFdagi klassga asoslangan viewda bir nechta imkoniyatlar mavjud. Masalan viewga murojaat qilish uchun cheklovlar qo'yish mumkin.

python
from rest_framework.permissions import IsAdminUser
from rest_framework.response import Response
from rest_framework.views import APIView

class ExampleView(APIView):
    permission_classes = [IsAdminUser]

    def get(self, request):
        return Response("You are admin user")

Yuqoridagi kodda viewga murojaat qilayotgan foydalanuvchi admin ekanligi tekshiriladi. Agar foydalanuvchi admin bo'lmasa, huquqi yo'qligi haqida xabar qaytaradi.

E'tibor bering

Bu holatda admin deganda admin panelga kirish huquqi bor foydalanuvchi nazarda tutilyapti. Super user bo'lishi shart emas.

Viewga tegishli boshqa o'zgaruvchi va metodlar bilan bu yerda tanishishingiz mumkin.
