Adding pagination

When you start adding content to your blog, you will soon realize you need to split the list of posts across several pages. Django has a built-in pagination class that allows you to manage paginated data easily.

Edit the views.py file of the blog application to import the Django paginator classes and modify the post_list view as follows:

from django.core.paginator import Paginator, EmptyPage,\
                                  PageNotAnInteger

def post_list(request):
    object_list = Post.published.all()
    paginator = Paginator(object_list, 3) # 3 posts in each page
    page = request.GET.get('page')
    try:
        posts = paginator.page(page)
    except PageNotAnInteger:
        # If page is not an integer deliver the first page
        posts = paginator.page(1)
    except EmptyPage:
 # If page ...
