Symfony3 & Assetic : different behavior in dev or prod

I'm working on Symfony 3.4 and Assetic. Let's say my website is www.mycompany.com and i'm using 2 particular types of asset :

• Google web font via @Import() in my main CSS file
• Custom CSS fonts, with font files manually uploaded in in web/fonts/

When i visit my website in dev mode www.mycompany.com/app_dev.php/ :

• Google fonts are well loaded and work.
• Font awesome doesn't work (beacause app_dev.php/fonts/ is 404)

When i visit my website in prod mode www.mycompany.com/ :

• Google fonts doesn't work (@import seems not to be loaded...)
• Font awesome work (because css files are found in www.mycompany.com/fonts/)

Why this behavior ? For your information, i use Assetic this way to load myu assets :

{% stylesheets '@PimInterfaceBundle/Resources/public/css/*' %}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}

// Same for JS

Thanks.

When using the cssrewrite filter, don't refer to your CSS files using the @XxBundle syntax.

try this

{% stylesheets 'bundles/piminterface/css/*' filter='cssrewrite' %}
    <link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}

here is doc

2. Fixing CSS Paths with the cssrewrite Filter

3. Dumping Asset Files in the prod Environment

if this is not working for you then try php bin/console asset:install

in prod php bin/console assetic:dump --env=prod --no-debug `
