Hello Django Community,
I am facing a problem using Paginator. All news are appearing on each page. The paginator looks broken also.
Could you help me with this one please.
Thank you

First, when sharing code, please do not post images. They’re not always readable on every device someone may be using to read these posts.
When you have code (or output) to share, enclose the text between two lines consisting only of three backtick (`) characters. (Make sure you use the backtick ` and not the apostrophe ')
Also label the block with the name of the file being included.
It looks like your view includes two custom mixins in addition to the standard ListView. Please post the code for those mixins - that’s going to be necessary to figure out what might be going wrong.
Good morning Mr KenWhitesell,
Thanks for your reply.
Sorry for my post.
As a new member I was allowed to post only one image and I didn’t knew how to share my code. Now I know thanks.
These are my mixins:
from django.views.generic import ListView, DetailView
from .models import News
from django.core.paginator import Paginator
from pages.models import Footer
class MultipleObjectsMixin(object):
def get_context_data(self, **kwargs):
ctx = super().get_context_data(**kwargs)
ctx['limited_news_list'] = News.objects.filter(status=1).order_by('-date')[:3]
ctx['cookie_vars'] = Footer.objects.all().first()
return ctx
class NoDraftPublishedMixin(object):
def get_context_data(self, **kwargs):
ctx = super().get_context_data(**kwargs)
ctx['news_list'] = News.objects.filter(status=1).order_by('-date')
return ctx
class NewsListView(MultipleObjectsMixin, NoDraftPublishedMixin, ListView):
model = News
context_object_name = 'news_list'
template_name = 'news/news_list.html'
paginate_by = 20
class NewsDetailView(MultipleObjectsMixin, DetailView):
model = News
template_name = 'news/news_detail.html'
slug_url_kwarg = 'slug'
Thank you again 
Ok, so the fundamental problem here is your mixins. You’ve written two mixins that are overriding what ListView is trying to do with your pagination.
You’re explicitly setting news_list in your get_context_data to the complete queryset instead of modifying the existing queryset, which would be the paged version, breaking the pagination logic that it would provide.
If you want to see how to write mixins that work with base classes rather than against the base class, look at some of the existing mixins from the Django code itself.
Ken
Ok. I will try this. Thank you 
There is an additional thought I’ll toss out here - you’ll probably want to modify/extend the get_queryset method rather than the get_context_data method if all you’re doing in your mixin is apply the filter and order_by clauses. You want to filter and sort the data before you extract your slices for the page, not after.
Ok thank you for your help. Will give you a feedback
Happy Birthday Ken,
It’s working, I spent a lot of time understanding what you meant
My NoDraftPublishedMixin was overriding my ListView
Will read more about mixins,
Thanks again
