python - Flask-Assets Bundles - Explanation of "ASSET_URL" for minify filters -


i'm implementing flask-assets, , i've read through documentation here:

but i'm still having trouble understanding going on asset_url variable when referencing minified output in template. example, shows here:

{% assets "js_all" %}     <script type="text/javascript" src="{{ asset_url }}"></script> {% endassets %}

can explain variable first introduced? feel flask-assets / bundle documentation makes lot of assumptions readers' knowledge of these topics , skips on details.

in test, asset_url seems serving original file template, not minified file. part of have:

application = flask(__name__,             static_url_path='',             static_folder='static') application.config["assets_debug"] = true  bundles = {     'index_js': bundle(         'js/index.js',         output='js/index-min.js',         filters='jsmin'), } assets = environment(application) assets.register(bundles)

...and in template:

{% assets "index_js" %}     <script type="text/javascript" src="{{ asset_url }}"></script> {% endassets %}

...but src served original file.

edit:

i realized "assets_debug" set true causes no minification occur. documentation makes seem not merge sources output, doesn't have effect.

however, helpful have more explanation concerning logic behind asset_url. can't seem track logic @ repo here.
