Setting up Localized Languages for the User Interface

There are two places to set language codes within arches. First, setttings.py contains languages specific to the Arches UI.

    ("de", _("German")),
    ("en", _("English")),
    ("en-gb", _("British English")),
    ("en-us", _("US English"))

Also set the LANGUAGE_CODE to be the default language code of your arches install.


Then, import the localized strings for the languages that will be used.

manage.py i18n loadmessages

This will attempt to load the translation files (po files) for every language specified in the LANGUAGES array from settings.py.

Setting up Localized Languages for Business Data

By default, every language from the LANGUAGES array in settings.py is available for business data entry. To add additional languages for business data entry only, you can do the following.

  1. Access the admin page (http://localhost:8000/admin/)

  2. Choose the “Languages” table. (http://localhost:8000/models/language)

  3. Select “Add Language”

  4. Fill in information on new language, including a default direction.

Repeat this process for all new languages you wish to add.

Additionally, remove any languages you do not plan on using.

Once this is complete, text widgets should be able to write data in the desired languages.

Creating PO Files for New Translations

To export Arches User Interface strings for translation into new languages, first make sure that the new language has been added to LANGUAGES in settings.py. Then, run the following command.

manage.py i18n makemessages

This will generate a new PO file with all of the Arches strings that need to be translated.

RDF Imports and Exports

Business data can be exported in RDF format. The directionality of the string data will be lost as the RDF specification does not include directionality. There is an active attempt to include direction within the RDF specification.

CSV Exports and Imports

It is possible to import and export localized business data through CSV format. There is a –language switch that will limit the languages that will be exported (all languages are exported by default). However, if attempting to re-import a limited subset of languages through the csv importer, entire string objects will be overwritten by the subset. For example, if a string node has values for English, Spanish, and French, the subset of languages can be limited by specifying

--languages en,es

If attempting to import the resulting csv, any values that were pre-existing for French would be overwritten in “overwrite” mode or added as a separate tile in “append” mode. There is currently no way to merge these values. If the intention is to re-import the csv values later, export all languages.

Additional Information

Text widgets default to the current UI language.
