How can i import a core translation into my own module?

Question

I found posts about how to let Mage use my own translation in core modules,

but not the other way.

What im trying is:

I overwrite core templates - in example module Mage_Sales.

The Block is like class My_Module_Block_My_View extends Mage_Core_Block_Template

The config.xml: ... <frontend> ... <translate> <modules> <My_Module> <files> <default>My_Module.csv</default> <need_this_too>Mage_Sales.csv</need_this_too> </files> </My_Module> </modules> </translate> ... </frontend> I think i tried every combination -- from using path app/locale/de_DE/Mage_Sales.csv to translate>modules>Mage_Sales>files>default>Mage_Sales.csv but nothing works.

Is there a way to import core translation .csv to my module ?

Answer 1

In the rewritten block, add the following method:

public function getModuleName()
{
    return 'Mage_Sales';
}

This way, the module used for translations is not determined by the class name anymore and the translations of Mage_Sales will be used.

If you need your own translations additionally, you can always use the module explicitly:

Mage::helper('my_module')->__('text to translate')
