Is it possible to create a conditional path to an asset using assetic and twig?

Question

Basically, I want to know if something like the following is possible:

<img src="{{ asset('bundles/acme/images' {% if something is defined %}'-blah{{ someId }}'{% endif %} '.png') }}" />

According to this the answer is likely no, but I want to make sure.

Answer 1

Why don't you put the if outside the asset-call like this:

<img src="
{%- if something is defined -%}
    {{ asset('bundles/acme/images-blah' ~ someId ~ '.png') }}
{%- else -%}
    {{ asset('bundles/acme/images-blah.png') }}
{%- endif -%}
" />
