Logging doesn't seem to work (p13)

[pentool]

Hello,

Reading the 'Quick Tour' PDF book (https://symfony.com/pdf/Symfony_quick_tour_4.2.pdf).

On page 13/14 there's a code sample for using logging.

public function index($name, LoggerInterface $logger) {
    $logger->info("Saying hello to $name!");
}

The new log message will be written to var/log/dev.log.

I have never worked with Symfony before (hence reading the Quick Tour book) so I am not sure why logging is not happening. There's nothing in the 'var/log' directory.

@pentool thanks for reporting this issue. I've checked the code and it looks correct. The error may be caused by something else. Usually, this is a permission issue (Symfony wants to write that log message, but it doesn't have permission to create the log file in that directory).

• Check out this article: https://symfony.com/doc/current/setup/file_permissions.html
• If the error persists, you can try asking in the #support channel of Symfony Slack (https://symfony.com/slack)

Also, since you are starting with Symfony, you may find the Symfony Demo app useful as a learning resource.
