php - How to load assets from a folder other than the web default folder? -

i load picture using asset() in twig template located in

sites/sf2.local/views/index.html.twig

and picture in

sites/sf2.local/assets/img/logo_om.gif

so in config.yml have added line : 

assetic:     read_from:      %kernel.root_dir%/../sites/sf2.local/assets/

but doesn't work, can't load picture using :

<img src="{{ asset('img/logo_om.gif') }}" alt="img" />

in twig template..

how can ?

first, think have mistaken assets assetic. twig function asset nothing more making assets absolute. not affect assets read from. described in docs:

linking assets

on other hand, assetic describes compiled (and optionally filtered, merged, uglified, etc...) resources read from. applies js , css.

possible solution:

open terminal, navigate web symlink directory:

cd /.../sf2/web ln -s ../sites/sf2.local/assets/img ln -s ../sites/sf2.local/assets/js ln -s ../sites/sf2.local/assets/css

now have 3 additional symlinks (not copies) in web , using asset('img/some-pic.png') targets symlinked img directory.

is symlinking acceptable?

alternative solution (whole assets):

cd /.../sf2/web ln -s ../sites/sf2.local/assets

and use it:

asset('assets/img/some-pic.png')
