How to create own application configuration?

zalizko

Hello everyone!
I'm starting with nette and confusing, I can't realize the elementary thing – own config.
For example I wold like to setup available languages in application.
I have added to the end of config.neon

languages: en; ru

and would like to get somehow this array in the BaseController.

Now my application uses this config throw error:
“Found sections ‘languages’ in configuration, but corresponding extensions are missing.”

Could anybody help me?

Jan Endel

this section have to be under section “parameters”, some like this:

parameters:
	languages:
		- en
		- ru

hope it helps

mm… ok! thanks for reply!
but now how to get this config from controller?

<?php
abstract class BasePresenter extends Nette\Application\UI\Presenter {
	protected function beforeRender() {
		var_dump($this->context->getParameters()['languages']);
	}
?>

right? Finally I have found only this way…

Clean way is to create a service, which will hold languages. Something like ‘LanguagesStorage’.

Define service:

services:
  - LanguagesStorage(%languages%)

Service class could look like this:

class LanguagesStorage extends Nette\Object
{
  private $languages = array();

  public function __construct(array $languages)
  {
    $this->languages = $languages;
  }

  public function getLanguages()
  {
    return $this->languages;
  }
}

Usage:

class AnyPresenter extends Presenter
{
  /** @var LanguagesStorage @inject */
  public $languagesStorage;

  public function renderDefault()
  {
    dump($this->languagesStorage->languages);
  }
}

And you can inject your service everywhere (in presenter via @inject, in other service via constructor).

Uhhh.. thanks! Looks clear now. Service for holding few parameters.. overhead..
Is it here some another way? these parameters in the config.neon, thay saves in the SystemConfigurer? How can I get access to him / her properties? All presenters are nested from BasePresenter then the main logic can be inside BasePresenter (or?).

offtop: one thing related to multilingual, how i can get current language? change it? of couse I can do it by sessio or other things, is there some functionallity out-of-the-box?
