Assetic error in Symfony 2.7

[foaly-nr1]

When warming up the cache, assetic is throwing the following error: assetic.ERROR: The template "GuzzleBundle::profiler.html.twig" contains an error: The function "dump" does not exist in "GuzzleBundle::profiler.html.twig" at line 47

This is because dump was introduced in added in Twig 1.5 and Symfony 2.7 seems to be using Twig 1.2.

Hi,

sorry for this late reply. Symfony 2.7.0 requires twig ~1.18. The bridge (posted link) requires ~1.20. Both versions are higher than 1.5. I'm not able to reproduce this error. Can you check which version of twig is installed by looking into composer.lock?

Best regards Florian

I have the same issue in my production environment. Symfony v2.6.10, Twig v1.18.2, GuzzleBundle v4.2.1.

This is because twig only loads the debug extension (with dump function) in debug mode. Run this with empty cache (rm -fr app/cache/prod) to confirm:

app/console assetic:dump --no-debug --env=prod

The problem is, that the method Dump is only available in environments with enabled debugging.

So in production, the dump method is not available.

see http://twig.sensiolabs.org/doc/functions/dump.html

The dump function is not available by default. You must add the Twig_Extension_Debug extension explicitly when creating your Twig environment:

Maybe we should write a custom twig function that uses the var_dump function with enabled debugging.

Yes, this could be a solution!

Reviving this thread: I wonder what's the point of having debug stuff available when you're warming up a non-debug cache. Couldn't we just "exclude" that when the kernel debug flag is set to false?
