How to translate twig to be compatible with 1.7.x

[arivei]

How to translate twig variables, ideally to be compatible with all 1.7 verisons of prestashop?

Only thing that works is $this->l() in mymodule.php

My twig:

{{ 'test3'|trans({}, 'Modules.Mymodule.Admin') }}

My php:

$this->displayName = $this->trans('text', [], 'Modules.Mymodule.Admin');

 

Module name is mymodule. I even removed the underscore from name, becouse I found it can be problem, it does look ugly and still don't work. What is the correct way? I copied the code from another PrestaShop modules and it seems to work fine there. But I do not see options to translate my module from backend, only the few I used $this->l at.

If you don't have it in translations. Check any tpl and change it directly.

I'm not sure I understand. I'm using the twig templating engine, not tpl. I want to translate text in this files (*.html.twig) to be compatible with PrestaShop 1.7.x.
