Symfony and Angular: shared translations

Angular for frontend with symfony delivering the data have become quite a common setup.

When working with this constellation you will sooner or later come across the i18n topic. Most likely you would want to share translations between front- and backend. So that you could keep translations in one single location while using it for frontend templates as well as server-side error messages etc.

One approach would be to store translations in the symfony yml or xml files and deliver those to the frontend via an api endpoint.
Given that front- and backend-code run on the same server, there is an even simpler solution.

Symfony Cache Component with SncRedisBundle

Since version 3.1 there is a Cache component with a PSR-6 implementation integrated in Symfony.

Doctrine Cache does the job but by implementing a standard the Symfony Cache seems to have another advantage besides its delievered anyway. So i checked it out.

[symfony 1.4] Class ‘sfLoader’ not found

Sollte man mal eine symfony 1.2.x Anwendung auf symfony 1.4.x migrieren und man stößt auf diesen Fehler:

Class 'sfLoader' not found

Dann hat man versucht einen Helper in der Action zu laden zB so:

sfLoader::loadHelpers('String');

Der sfLoader ist in 1.4 allerdings entfernt worden.
Stattdessen sollte man dann sowas schreiben:

$this->getContext()->getConfiguration()->loadHelpers('String');

Dann klappts.
