Algolia Search for Django

This package lets you easily integrate the Algolia Search API to your Django project. It's based on the algoliasearch-client-python package.

You might be interested in this sample Django application providing a typeahead.js based auto-completion and Google-like instant search: algoliasearch-django-example

Compatible with Python 2.7, Python 3.2+ and Django 1.7+

Setup

Install

pip install algoliasearch-django

Setup

In your Django settings, add django.contrib.algoliasearch to INSTALLED_APPS and add these two settings:

ALGOLIA = {
    'APPLICATION_ID': 'MyAppID',
    'API_KEY': 'MyApiKey'
}

There are two optional settings:

  • INDEX_PREFIX: prefix all indexes. Use it to separate different applications, like site1_Products and site2_Products.
  • INDEX_SUFFIX: suffix all indexes. Use it to differenciate development and production environment, like Location_dev and Location_prod.
  • AUTO_INDEXING: automatically synchronize the models with Algolia (default to True).

Quick Start

Simply call AlgoliaSearch.register() for each of the models you want to index. A good place to do this is in your application's AppConfig (generally named apps.py). More info in the documentation

from django.apps import AppConfig
from django.contrib import algoliasearch

class YourAppConfig(AppConfig):
    name = 'your_app'

    def ready(self):
        YourModel = self.get_model('your_model')
        algoliasearch.register(YourModel)

And then, don't forget the line below in the __init__.py file of your Django application.

default_app_config = 'your_django_app.apps.YourAppConfig'

By default, all the fields of your model will be used. You can configure the index by creating a subclass of AlgoliaIndex. A good place to do this is in a separate file, like index.py.

from django.contrib.algoliasearch import AlgoliaIndex

class YourModelIndex(AlgoliaIndex):
    fields = ('name', 'date')
    geo_field = 'location'
    settings = {'attributesToIndex': ['name']}
    index_name = 'my_index'

And then replace algoliasearch.register(YourModel) with algoliasearch.register(YourModel, YourModelIndex).

Commands

Commands

  • python manage.py algolia_reindex: reindex all the registered models. This command will first send all the record to a temporary index and then moves it.
    • you can pass --model parameter to reindex a given model
  • python manage.py algolia_applysettings: (re)apply the index settings.
  • python manage.py algolia_clearindex: clear the index

Search

Search

We recommend the usage of our JavaScript API Client to perform queries directly from the end-user browser without going through your server.

However, if you want to search from your backend you can use the raw_search(YourModel, 'yourQuery', params) method. It retrieves the raw JSON answer from the API.

from django.contrib.algoliasearch import raw_search

params = { "hitsPerPage": 5 }
raw_search(Contact, "jim", params)

Geo-Search

Geo-Search

Use the geo_field attribute to localize your record. geo_field should be a callable that returns a tuple (latitude, longitude).

class Contact(models.model):
    name = models.CharField(max_lenght=20)
    lat = models.FloatField()
    lng = models.FloatField()

    def location(self):
        return (self.lat, self.lng)


class ContactIndex(AlgoliaIndex):
    fields = 'name'
    geo_field = 'location'


algoliasearch.register(Contact, ContactIndex)

Multiple geolocations are supported, for instance:

class Location(models.Model):
    lat = models.FloatField()
    lng = models.FloatField()

class Contact(models.Model):
    name = models.CharField(max_lenght=20)
    locations = models.ManyToManyField('Location')

    def geolocations(self):
        return [
            {'lat': location.lat, 'lng': location.lng}
            for location in self.locations.all()
        ]


class ContactIndex(AlgoliaIndex):
    fields = 'name'
    geo_field = 'geolocations'


algoliasearch.register(Contact, ContactIndex)

Tags

Tags

Use the tags attributes to add tags to your record. It can be a field or a callable.

class ArticleIndex(AlgoliaIndex):
    tags = 'category'

At query time, specify { tagFilters: 'tagvalue' } or { tagFilters: ['tagvalue1', 'tagvalue2'] } as search parameters to restrict the result set to specific tags.

Options

Custom objectID

You can choose which field will be used as the objectID. The field should be unique and can be a string or integer. By default, we use the pk field of the model.

class ArticleIndex(AlgoliaIndex):
    custom_objectID = 'post_id'

Custom index name

You can customize the index name. By default, the index name will be the name of the model class.

class ContactIndex(algoliaindex):
    index_name = 'Enterprise'

Index settings

We provide many ways to configure your index allowing you to tune your overall index relevancy. All the configuration is explained on our website.

class ArticleIndex(AlgoliaIndex):
    settings = {
        'attributesToIndex': ['name', 'description', 'url'],
        'customRanking': ['desc(vote_count)', 'asc(name)']
    }

Restrict indexing to a subset of your data

You can add constraints controlling if a record must be indexed or not. should_index should be a callable that returns a boolean.

class Contact(models.model):
    name = models.CharField(max_lenght=20)
    age = models.IntegerField()

    def is_adult(self):
        return (self.age >= 18)

class ContactIndex(AlgoliaIndex):
    should_index = 'is_adult'

Tests

Run Tests

To run the tests, first find your Algolia application id and Admin API key (found on the Credentials page).
