Configured region not honored with de-informal language

[stapelberg]

Problem and impact

When setting my user account’s language to de-informal, the configured region (CH) is no longer honored for formatting money values, e.g. in the orders page.

Expected behaviour

No response

Steps to reproduce

1. Configure region to CH
2. Configure language to de; orders page lists “CHF 97.56” (with dots)
3. Configure language to de-informal; orders page lists “97,56 CHF” (with commas)

Looking at the code, I think the problem is that the language function treats “informal” as a region:

pretix/src/pretix/base/i18n.py

Lines 146 to 154 in 6bf23b0

	_lng = translation.get_language()
	lng = lng or settings.LANGUAGE_CODE
	if '-' not in lng and region:
	lng += '-' + region.lower()
	translation.activate(lng)
	try:
	yield
	finally:
	translation.activate(_lng)

I'll look into it but it might be not fixable the way the informal variant is implemented, it's basically a fake region in itself :/

[stapelberg]

Wouldn’t just removing “-informal” before trying to determine the region fix the problem?

No, the region will not be added to the language in the first place if de-informal is used since "informal" is implemented like a region (think de-de, de-at, de-ch and de-informal)
