Overview

A better way than DRF proposed for do some basic filters

Requirements

• Python (2.7,3.2,3.3,3.4, 3.5 -with Django 1.8-)

• Django (1.7, 1.8)

• Django REST Framework (3.0, 3.1, 3.2)

Installation

Install using pip…

$ pip install drf-lafv

Example

Imagine that you have the following models.py

from django.db import models


class Author(models.Model):
    name = models.CharField(max_length=250)
    nickname = models.CharField(max_length=100)


class Book(models.Model):
    title = models.CharField(max_length=200)
    description = models.TextField()
    publication_date = models.DateField()
    isbn = models.CharField(max_length=17)
    author = models.ForeignKey(Author)

And you want to filter your list of books by author’s nickname, isbn and create a custom filter which will allow to get you books that were published less than 30 days ago. Well, DRF per se, ask you to install django-filter and write a bunch of stuff that maybe hard. With lafv you can accomplish this doing this:

from lafv.views import ListAPIFilteredView
from serializers import BookSerializer


class BookView(ListAPIFilteredView):
    queryset = Book.objects.all()
    serializer_class = BookSerializer
    filter_fields = ('author__nickname', 'isbn')
    custom_filters = ('new', )

    def filter_new(self, queryset):
        """
        get books that publication date is no longer than 1 month
        """
        last_month = datetime.today() - timedelta(days=30)
        queryset = queryset.filter(publication_date__gte=last_month)
        return queryset

And that’s it!, please check the examples on the test app

Testing

Install testing requirements.

$ pip install -r requirements.txt

Run with runtests.

$ ./runtests.py

You can also use the excellent tox testing tool to run the tests against all supported versions of Python and Django. Install tox globally, and then simply run:

$ tox
