Javascript url handling for Django that doesn't hurt.

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.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'
