Simple queryset ​

Bu darsda bazada turgan ma'lumotlarni html fayl orqali browser oynasida ko'rsatishni o'rganamiz.

Avval product/views.py fayliga kiramiz, funksiya ichida bazadan barcha Product modeliga tegishli obyektlarni olish kodini yozamiz va bu ma'lumotlarni o'zgaruvchiga biriktirib, html faylga uzatamiz.

python
from django.shortcuts import render

import datetime

from .models import Product

def example(request):
    products = Product.objects.all()
    
    return render(request, 'example.html', {
        'sana': str(datetime.date.today()),
        'ism': 'Asliddin',
        'products': products
    })
from django.shortcuts import render

import datetime

from .models import Product

def example(request):
    products = Product.objects.all()
    
    return render(request, 'example.html', {
        'sana': str(datetime.date.today()),
        'ism': 'Asliddin',
        'products': products
    })

Bu yerda queryset

python
products = Product.objects.all()
products = Product.objects.all()

va bu querysetning eng oddiy ko'rinishi.

Endi example.htmlga quyidagi o'zgarishlarni kiritamiz.
