The translation of the user interface is provided module-wise.
Translations are stored in the locale/ directory of a module, each language
in a PO-file. The
official language files are named after the
POSIX locale
standard, e.g. de_DE.po, es.po, es_AR.po, es_EC.po...
The names of custom language files must match the code of the language in the Model ir.lang.
If a language is set translatable, the translations will be loaded into
the database on each trytond module update.
Tryton supports derivative translations. This means that if the translation of a term is missing in one language, it will search on the parent languages. Also when activate a children language, you must also activate all parents.
The wizard adds new translations to the base language en.
The wizard deletes obsolete translations from the database.
The wizard updates the translations of the selected language based on the
translations of the base language en. It will also remove duplicate
translations with its direct parent.
The wizard requires to select a language and a module and will export the translations for this selection into a PO-file.
Translations of a module can be overridden by another module. This can be done
by putting a PO file into the locale/override directory of the module that
shall contain the translations to override.
To override the translation of another module the msgctxt string must have
the following content:
type:name:module.xml_id
type: Value of the field type of ir.translation.name: Value of the field name of ir.translation.module: Value of the field module ir.translation.xml_id: The XML id that is stored in ir.model.data as fs_id
The xml_id part is optional and can be omitted if it is None.
