views.py

from django.core.paginator import Paginator,EmptyPage,InvalidPage

def sort(request,value):
    category = Category.objects.all()
    if(value=='2'):
        products_list = Product.objects.all().order_by('price')
    elif(value=='3'):
        products_list = Product.objects.all().order_by('-price')
    elif(value=='4') :
        products_list = Product.objects.all().order_by('-id')
    elif (value == '5'):
        products_list = Product.objects.all().order_by('-view')

    paginator = Paginator(products_list,5)
    try:
        page=int(request.GET.get('page','1'))
    except:
        page = 1

    try:
        products = paginator.page(page)
    except(EmptyPage,InvalidPage):
         products = paginator.page(paginator.num_pages)
    context = {
        'products': products,'category': category,'value' : value
