How to implement pagination in Search results in django?
I found a resource where it has code like this:
from django.contrib.auth.models import User
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
def index(request):
user_list = User.objects.all()
page = request.GET.get('page', 1)
paginator = Paginator(user_list, 10)
try:
users = paginator.page(page)
except PageNotAnInteger:
users = paginator.page(1)
except EmptyPage:
users = paginator.page(paginator.num_pages)
return render(request, 'core/user_list.html', 'users': users )
I have a code like this:
def product_list(request, category_slug=None):
category = None
categories = Category.objects.all().order_by("-rating")
#paginator = Paginator(categories, 10)
products = Product.objects.all().order_by("-number")
users = User.objects.exclude(id=request.user.id)
query = request.GET.get('q')
if query=='':
return HttpResponseRedirect('/')
if query:
categories = Category.objects.filter(Q(slug__icontains=query)| Q(url__icontains=query)).order_by("-rating")
products = Product.objects.filter(Q(slug__icontains=query) | Q(name__icontains=query) | Q(description__icontains=query)).order_by("number")
if category_slug:
category = get_object_or_404(Category, slug=category_slug)
products = Product.objects.filter(category=category)
categories_counter = products.annotate(Count('id'))
categories_count = len(categories_counter)
#contacts = paginator.get_page(query)
context =
'category': category,
'categories': categories,
'products': products,
'categories_count':categories_count,
'query':query,
'users':users,
#'contacts':contacts,
return render(request, 'shop/product/list.html', context)
I have retrieved objects from two models, Category, and Product. How do I implement the pagination code in this view? It's not a normal pagination but pagination in search results.

user_list = User.objects.all() # this is the full queryset, contains all objects
page = request.GET.get('page', 1) # this is the page number of page whose data you want to retrieve, you need to pass page value as query params
paginator = Paginator(user_list, 10) # this will paginate the full queryset in pages of 10 objects
try:
users = paginator.page(page) # this will return data of that particular page
except PageNotAnInteger:
users = paginator.page(1) # if the passed page is not Integer then first page is returned, you can customize this
except EmptyPage:
users = paginator.page(paginator.num_pages) # if that page contains no element, then last page is returned, you can customize this also
You can apply same logic to retrieve categories in category_page and other data.
category_page
