Fixing incorrect/missing translations due to legalities

Internationalization and Localization
1

We are trying to hold a Turkish event, and the universities have some strict legal restrictions on the terms. Unfortunately, the Turkish translation has significant number of “incorrect” (i.e. not legally acceptable) translations and missing translations.

I tried to fix this by editing “indico/translations/tr_TR/LC_MESSAGES/messages.po” in the venv, followed by a restart of services “systemctl restart nginx.service indico-celery.service indico-uwsgi.service”

However, my changes are ignored, and the generated PDF documents (pages) still insist on “incorrect” translations or direct English.

Is there a solution to this problem?

Indico 3.2.1 installed directly using the standard instructions

Hi, try running indico i18n compile-catalog. Note that such manual changes will be lost during an upgrade.
Afterwards you only need to restart uwsgi and celery; no need to restart nginx.

PS: If there are mistakes feel free to contribute fixes to our translations on Transifex; those will end up in an upcoming release and thus be available for everyone! See this page in the docs for details.

That did the trick! Thank you very much. I didn’t think that section of the manual was relevant to my case, I’ll push my translations to there as well.

Btw, the command failed at first with

I just deleted the translation, since I don’t need it.

Also, my react translation compilation failed. First, because I didn’t have npm installed, second for some reason I don’t clearly understand. This is not super important to me at the moment, but FYI the error message is attached.

The chinese errors are safe to ignore, no need to delete anything.

Compiling react translations does NOT work in a production setup (since it requires the JS build env which is not present in production). Generally the way to go is to make a dev setup on another machine, compile the translations there, and then build a new Python wheel to install on production.
See Building — Indico 3.2.2 documentation on how to build an Indico Python wheel.
