Symfony2 disable cache?

Question

Is there a way to disable the caching function in Symfony2? I tried to find the setting in the config* and parameters.ini files and I searched a lot. Ok, I found a few solutions, but nothing for the latest version (Symfony2).

WHY? Because I want to test new templates and functions without clearing the app/cache* all the time.

Solution 1

I'm assuming you're using the Twig engine, (the default templating engine for Symfony2). To disable caching in twig, so that you do not have to keep clearing the cache like so:

rm -rf app/cache/*

Navigate to your app config file (by defualt will be located in ../app/config/config.yml from your root directory). Scroll to the twig configuration settings (under twig:) and change the cache value (which should be pointing to the cache directory) to false like so:

twig:
    cache:  false

If you do not see any cache configuration entry, simply add the line above.

It may also be helpful to checkout the configuring reference for the Twig bundle: http://symfony.com/doc/2.0/reference/configuration/twig.html

After editing your config_dev.yml file, go to your terminal and run:

app/console cache:clear

Solution 2

Okay, regarding your clarification the solution simply is to use the dev-environment through the front-controller web/app_dev.php. Then sf2 keeps track of your adjustments and you don't have to clear the cache.

This original solution works for me http://symfony.com/doc/current/cookbook/debugging.html

Solution 4

In addition to the accepted answer, I propose to edit your config_dev.yml in a way so it still debugs your twig template. To do so, add this code to your config_dev.yml file:

twig:
    cache: false
    debug: true

services:
    twig.extension.debug:
        class: Twig_Extension_Debug
        tags:
                - { name: 'twig.extension' }

After editing your config_dev.yml file, go to your terminal and run:

app/console cache:clear

By doing so, you will reload your config_dev.yml settings - make your project run with the new configuration.

Hope this helps.

Edit 'config_dev.yml' and 'config.yml' and then put in both

twig:
    cache:  false

Hi All, i tried the provided solution and all i get now from twig is a blank page. i never had the cache option in my yml file. Anyone has an idea .. ?

I recommend disabling the twig cache on app_dev.php only. It works fine and stays away from your production configuration.

How do you disable twig cache in app_dev.php? All of the documentation say that app_dev.php by default disables twig cache, but im not seeing this behavior.

That link does not show how to set twig to recompile on each request.

Saved hours of my time doing this instead of cache:clear everytime I make change to a template!

[Mike W]

you mention both config.yml and config_dev.yml. Do both need to be modified?
