django-searchable-select
========================

A better and faster multiple selection widget with suggestions for
Django

What is this?
=============

This plugin provides a replacement for standard multi-choice select on
Django admin pages.

You can use this as custom widget for ``ManyToManyField``.

Features
========

- Filtering is performed on server side and thus significantly improves
performance.
- Uses ``Twitter Typeahead`` to provide suggestion completion.
- Works **great** with ManyToMany fields that can be chosen from
thousands of thousands of choices, e. g. ``User - City`` relations.

Installation
============

1. Install ``django-searchable-select``.

.. code:: sh

$ pip install django-searchable-select

2. Add ‘searchableselect’ to your settings.

.. code:: python

# settings.py

INSTALLED_APPS = (
# ...
'searchableselect',
# ...
)

3. Add URL pattern required for the suggesting engine to your root
``urls.py``.

.. code:: python

# urls.py

urlpatterns = patterns(
'',
# ...
url('^searchableselect/', include('searchableselect.urls')),
# ...
)

4. Use the widget in your model admin class:

.. code:: python

from django import models, forms
from searchableselect.widgets import SearchableSelect
from models import Traveler

class TravelerForm(forms.ModelForm):
class Meta:
model = Traveler
exclude = ()
widgets = {
'cities_visited': SearchableSelect(model='cities.City', search_field='name')
}


class TravelerAdmin(admin.ModelAdmin):
form = TravelerForm

admin.site.register(Traveler, TravelerAdmin)

Remember to **always** initialize ``SearchableSelect`` with three
keyword arguments: ``model``, ``search_field`` and ``many``.

- ``model`` is the string in form ``APP_NAME.MODEL_NAME``
representing your model in the project, e. g. ‘cities.City’
- ``search_field`` is the field within model that will be used to
perform filtering, e. g. ‘name’
- ``many`` must be ``True`` for ``ManyToManyField`` and ``False``
for ``ForeignKey``.

Example app │
===========
│
Just run the project from `example` directory, head to http://127.0.0.1:8000, login as ``admin``/``admin`` and try adding Cats!
