Javascript url handling for Django that doesn't hurt.
Project description
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/

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
{% 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)
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'
Running the test suite
make test
