To make a website Good Performance, then paginate the page.

How to work with Django Pagination

In this section, you will learn to paginate your Django web page using a predefined class. We will give a suitable example which will help you to understand better. So let’s start, how you can work with Django Pagination.

As we have discussed we can paginate a Django web page using the Paginator class. Because all the methods, to getting objects, next, previous, number of items per page, etc are existing in this class. We can paginate a page in two ways, high level, and low level.

from django.core.paginator import Paginator
persons= [‘faisal’, ‘zamir’, ‘khalid’, ‘amir’,’asif’,’ yasir’]
page = Paginator(persons, 3)

page .count
6

page .num_pages

The explanation of each line of code for you:

At the first line of code, you have to import this class to work with pagination, without importing you can get all these methods, functions, etc.

In the 2nd line of code we have created a list, included some person’s name. In that list, we will apply different methods of paginator class.

We used the paginator function which taking 2 arguments. one is showing a list of objects, 2nd argument showing that how many objects you want to display per page.

The count method will return the total number of objects in the list

The num_pages means it will return how many pages will be made, after dividing all the objects.

type(person.page_range)
<class ‘range_iterator’>
person.page_range
range(1, 3)

In the above lines of code, we are finding the type of page range which means what is the range of page. the range is the function in core python which give a range of number from start to end with a defined step. So, we can find a range of pages that were created using pagination.

So in the end, we got range(1,3) it means that there are two pages 1 and 2. Last argument 3, always minus 1 which gives 2.
