Javascript url handling for Django that doesn't hurt.
Project description
Javascript url handling for Django that doesn’t hurt.
This package is now maintained by Vinta Software but it was originally created by @ierror. Many thanks to you, Bernhard.
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.betterlivingGetHouse('house', 12)
Result:
/betterliving/house/12/

Installation
Install using pip …
pip install django-js-reverse
… or clone the project from github.
git clone https://github.com/ierror/django-js-reverse.git
Add 'django_js_reverse' to your INSTALLED_APPS setting.
INSTALLED_APPS = ( ... 'django_js_reverse', )
Usage with webpack
Install using npm
npm install --save django-js-reverse
Include none-cached view …
urlpatterns = patterns('', url(r'^jsreverse.json$', 'django_js_reverse.views.urls_json', name='js_reverse'), )
… or a cached one that delivers the urls JSON
from django_js_reverse import views urlpatterns = patterns('', url(r'^jsreverse.json$', cache_page(3600)(views.urls_json), name='js_reverse'), )
Include JavaScript in your bundle:
// utils/djangoReverse.mjs import _ from 'lodash/fp'; import djangoJsReverse from 'django-js-reverse'; export default _.once( async () => { const res = await fetch('/jsreverse.json'); const data = await res.json(); return djangoJsReverse(data); } )
// somePlace.mjs import djangoReverse from './utils/djangoReverse'; (async () => { const urls = await djangoReverse(); const url = urls.someViewName('some-arg'); ... })();
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
You can place the js_reverse JavaScript inline into your templates, however use of inline JavaScript is not recommended, because it will make it impossible to deploy a secure Content Security Policy. See django-csp
{% 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.betterlivingGetHouse('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)
You can also pass javascript objects to match keyword aguments like the examples bellow:
Urls['betterliving-get-house']({ category_slug: 'house', entry_pk: 12 }) Urls['namespace:betterliving-get-house']({ category_slug: 'house', entry_pk: 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 = 'window'
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 want to include only specific namespaces add them to the JS_REVERSE_INCLUDE_ONLY_NAMESPACES setting tips: * Use “” (empty string) for urls without namespace * Use “foo0” to include urls just from “foo” namaspace and not from any subnamespaces (e.g. “foo:bar”)
JS_REVERSE_INCLUDE_ONLY_NAMESPACES = ['poll', 'calendar', ...]
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/'
By default collectstatic_js_reverse writes its output (reverse.js) to your project’s STATIC_ROOT. You can change the output path:
JS_REVERSE_OUTPUT_PATH = 'some_path'
