Overview

Suppose your models.py looks something like this:

class Book(models.Model):
    name = models.CharField(max_length=100)
    binding = models.CharField(max_length=2, choices=BINDING_CHOICES)
    authors = models.ManyToManyField(Author)
    genre = models.ForeignKey(Genre)
    price = models.DecimalField(max_digits=6, decimal_places=2)
    date_published = models.DateField()

(with BINDING_CHOICES, Author and Genre omitted for brevity).

You might want to present a list of Book objects, allowing the user to filter on the various fields. Assuming your views.py is something like this:

from myapp.models import Book

def booklist(request):
    books = Book.objects.all()
    return render(request, "booklist.html", {'books': books})

and the template is like this:

{% for book in books %}
   {# etc #}
{% endfor %}

To add the filters, in views.py add a FilterSet subclass and change the view code as follow:

from django_easyfilters import FilterSet
from myapp.models import Book

class BookFilterSet(FilterSet):
    fields = [
        'binding',
        'authors',
        'genre',
        'price',
        ]

def booklist(request):
    books = Book.objects.all()
    booksfilter = BookFilterSet(books, request.GET)
    return render(request, "booklist.html", {'books': booksfilter.qs,
                                             'booksfilter': booksfilter})

Notice that the books item put in the context has been replaced by bookfilter.qs, so that the QuerySet passed to the template has filtering applied to it, as defined by BookFilterSet and the information from the query string (request.GET).

The booksfilter item has been added to the context in order for the filters to be displayed on the template.

Then, in the template, just add {{ booksfilter }} to the template. books. You can also use pagination e.g. using django-pagination:

{% autopaginate books 20 %}

<h2>Filters:</h2>
{{ booksfilter }}

{% paginate %}

<h2>Books found</h2>
{% for book in books %}
   {# etc #}
{% endfor %}

Customisation of the filters can be done in various ways - see the FilterSet documentation for how to do this, and the Filters documentation for options that can be specified.
