django-js-asset 0.1.1

Usage

Use this to insert a script tag via forms.Media containing additional attributes (such as id and data-* for CSP-compatible data injection.):

from js_asset import JS

media.add_js([
    JS('asset.js', {
        'id': 'asset-script',
        'data-answer': '"42"',
    }),
])

The rendered media tag (via {{ media.js }} or {{ media }} will now contain a script tag as follows, without line breaks:

<script type="text/javascript" src="/static/asset.js"
    data-answer="&quot;42&quot;" id="asset-script"></script>

The attributes are automatically escaped. The data attributes may now be accessed inside asset.js:

var answer = document.querySelector('#asset-script').dataset.answer;

Also, because the implementation of static differs between supported Django versions (older do not take the presence of django.contrib.staticfiles in INSTALLED_APPS into account), a js_asset.static function is provided which does the right thing automatically.
