django-select2-rocks 0.9.0

Installation

1. pip install django_select2_rocks

2. add select2rocks to your INSTALL_APPS

3. python manage.py collectstatic will install Django Select2 Rocks JS.

4. Include jQuery (1.7+), Select2 JS/CSS (not provided, tested with v3.4.5) and select2rocks/select2rocks.js in your templates.

5. Now, you can use Select2ModelChoiceField fields in your forms.

Design

Django-select2-rocks provides widgets to render and initialize Select2 inputs.

The widget rendering is based on Django with a further step which adds a JS initialization for each input (on DOM ready). When a character is typed in the input field, an AJAX request is sent to the URL associated to the field.

The widget API is designed to allow you to pass any arguments you want to Select2 JS code (eg. allowClear option).

You can use various JSON views to answer to Select2 AJAX queries, and so to adjust search terms or the format of the results, it’s possible to extend the default django-select2-rocks backend (see select2rocks-backends.js in testproj for an example).

Example

The testproj project contains examples with a simple JSON view and a Django REST framework view.

import select2rocks

class BeachForm(forms.Form):
    beach = select2rocks.Select2ModelChoiceField(
        queryset=Beach.objects.all(),
        widget=select2rocks.AjaxSelect2Widget(url_name='json_beaches'))

Subtleties

Beware, the internal representation of the fields uses commas (,) to separate items. Thus you cannot use commas in your labels. Otherwise we’ll interpret it as a separator and try to work with the text on both sides of the comma, which will most likely break.
