Django JS Reverse

Javascript url handling for Django that doesn’t hurt.

Overview

Django JS Reverse is a small django app that makes url handling of named urls in javascript easy and non-annoying..

For example you can retrieve a named url:

urls.py:

url(r'^/betterliving/(?P<category_slug>[-\w]+)/(?P<entry_pk>\d+)/$', 'get_house', name='betterliving_get_house'),

in javascript like:

Urls.betterliving_get_house('house', 12)

Result:

/betterliving/house/12/

Full changelog

Requirements

• Python (2.6, 2.7, 3.1, 3.3, 3.4, PyPy)
• Django (1.4, 1.5, 1.6, 1.7)

Installation

Install using pip …

pip install django-js-reverse

… or clone the project from github.

git clone [email protected]:ierror/django-js-reverse.git

Add 'django_js_reverse' to your INSTALLED_APPS setting.

INSTALLED_APPS = (
    ...
    'django_js_reverse',
)

Usage as static file

First generate static file by

./manage.py collectstatic_js_reverse

If you change some urls or add an app and want to update the reverse.js file, run the command again.

After this add the file to your template

<script src="{% static 'django_js_reverse/js/reverse.js' %}"></script>

Usage with views

Include none-cached view …

urlpatterns = patterns('',
    url(r'^jsreverse/$', 'django_js_reverse.views.urls_js', name='js_reverse'),
)

… or a cached one that delivers the urls javascript

from django_js_reverse.views import urls_js
urlpatterns = patterns('',
    url(r'^jsreverse/$', cache_page(3600)(urls_js), name='js_reverse'),
)

Include javascript in your template

<script src="{% url js_reverse %}" type="text/javascript"></script>

or, if you are using Django > 1.5

<script src="{% url 'js_reverse' %}" type="text/javascript"></script>

Usage as template tag

{% load js_reverse %}

<script type="text/javascript" charset="utf-8">

{% js_reverse_inline %}

</script>

Use the urls in javascript

If your url names are valid javascript identifiers ([$A-Z_][-Z_$]*)i you can access them by the Dot notation:

Urls.betterliving_get_house('house', 12)

If the named url contains invalid identifiers use the Square bracket notation instead:

Urls['betterliving-get-house']('house', 12)
Urls['namespace:betterliving-get-house']('house', 12)

Options

Optionally, you can overwrite the default javascript variable ‘Urls’ used to access the named urls by django setting

JS_REVERSE_JS_VAR_NAME = 'Urls'

Optionally, you can change the name of the global object the javascript variable used to access the named urls is attached to. Default is this

JS_REVERSE_JS_GLOBAL_OBJECT_NAME = False

Optionally, you can disable the minfication of the generated javascript file by django setting

JS_REVERSE_JS_MINIFY = False

By default all namespaces are included

JS_REVERSE_EXCLUDE_NAMESPACES = []

To exclude any namespaces from the generated javascript file, add them to the JS_REVERSE_EXCLUDE_NAMESPACES setting

JS_REVERSE_EXCLUDE_NAMESPACES = ['admin', 'djdt', ...]

If you run your application under a subpath, the collectstatic_js_reverse needs to take care of this. Define the prefix in your django settings:

JS_REVERSE_SCRIPT_PREFIX = '/myprefix/'
