Overview

Suppose your model.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 have a 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, you add the following:

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Notice that the books item put in the context has been replaced by bookfilter.qs, so that the QuerySet passed to the template has filtering applied to it, as defined by BookFilterSet and the information from the query string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, 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 using a tuple containing (field_name, dict of options), instead of just field_name:

class BookFilterSet(FilterSet):
    model = Book
    fields = [
        'binding',
        ('genre', dict(order_by_count=True))
    ]

See the Filters documentation for options that can be specified. See the FilterSet documentation for ways to customize the rendering of the filters.
