Symfony2 / prod：未生成css和javascript文件名

Question

After moving my symfony2 app to production, my homepage and and links related to the frontend part work fine (domain.com/event/xxxx, domain.com/category/yyy etc). CSS & JS are correctly loaded. However, my admin part which is accessible via domain.com/admin is not. When I check out the generated html, I find my CSS & JS filenames are null.

I am getting something like

<link rel="stylesheet" href="/css/.css"> 
<script src="/js/.js"></script>

I have cleared cache and dumped assetic :

./console cache:clear --env=prod --no-debug
./console assetic:dump --env=prod --no-debug

but nothing happens, the problem persists.

BTW, clearing the prod cache displays weird lines that do not show I clear the dev cache, I get some output like this :

Clearing the cache for the prod environment with debug false Mac OS X           2??ATTR?????j?

If you need to see my config files, just tell me which files you need and I will paste them.

Any help please ?

EDIT

ok I don't know if this is correct or not, but I found this Assetic not creating combined links

and after changing $kernel = new AppKernel('prod', false);

by (the opposite of what is described in that link), it is working. $kernel = new AppKernel('prod', true);

Can I keep it like that ?

Answer 1

I've solved this with

app/console cache:clear --env=prod --no-debug
app/console cache:warmup --env=prod
app/console assets:install --symlink
app/console assetic:dump --env=prod --no-debug

These commands helped me when the CSS was not loading. I always like to clear my caches whenever doing stuff like this. app/console assetic:dump --env=prod I think is the command that makes this work since it is the one that compiles the CSS and JS into one file.
