Turn off Twig cache

Question

I did Disable Drupal 8 caching during development step by step ( also finally rebuild the cache) but yet my changes in twig files not take effects without rebuild the cache.

sites/default/services.yml :

parameters:
    session.storage.options: { gc_probability: 1, gc_divisor: 100, gc_maxlifetime: 200000, cookie_lifetime: 2000000 }
    twig.config: { debug: true, auto_reload: true, cache: false }

sites/default/settings.php :

 if (file_exists(__DIR__ . '/settings.local.php')) {
   include __DIR__ . '/settings.local.php';
 }

sites/default/settings.local.php :

$settings['container_yamls'][] = DRUPAL_ROOT . '/sites/development.services.yml';
$config['system.performance']['css']['preprocess'] = FALSE;
$config['system.performance']['js']['preprocess'] = FALSE;

sites/development.services.yml :

services:
  cache.backend.null:
    class: Drupal\Core\Cache\NullBackendFactory
parameters:
  twig.config:
    debug: true
    auto_reload: true
    cache: false

Where is the Problem?

Answer 1

I resolved my problem by following lines in settings.local.php.

# $settings['cache']['bins']['render'] = 'cache.backend.null';

duplicate the line and enable it (by remove # before it) and change render to dynamic_page_cache I mean the following line resolved your issue

 $settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.null';

in Drupal >= 8.8 use

  $settings['cache']['bins']['render'] = 'cache.backend.memory';

Answer 2

In Drupal 8.8 adding this to sites/default/settings.local.php worked for me:

$settings['cache']['bins']['render'] = 'cache.backend.memory';

For some reasons when I try to add it as recommended ('cache.backend.null') I have the following error

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "cache.backend.null". Did you mean one of these: "cache.backend.apcu", "cache.backend.memory", "cache.backend.php"?

Answer 3

Now there is a SUPER EASY way to do this. Install the Mix module, and toggle the Enable development mode checkbox to turn off/on twig cache and other caches with just a click. No need to edit settings.php and *services.yml files back and forth.

Answer 4

For those who are struggling for configuring caching for Drupal 8, the following steps resolve the issue.

• Copy the example.settings.local.php which is located outside of the files folder into files folder with settings.local.php
• Uncomment $settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.null';
• Uncomment $settings['cache']['bins']['page'] = 'cache.backend.null'; too
