'max_digits' must be great or equal to 'decimal_places' on OpenBSD

[xc3seziu]

Python 3.6.5
Django 1.11.15
Mezzanine 4.3.0
Cartridge 0.13.0

I've seen this issues on other platforms but haven't been able to find the issue on OpenBSD. Local (LC_ALL) is set to en_US.UTF-8 (this was listed as a possible culprit in some situations).

Here's the full error when I run './manage.py createdb':

./manage.py createdb

That issue actually came up for me (on a fresh install on a brand-spanking-new Ubuntu 18.04 system). It seems to be a locale issue. Please see:

#4

Since my locale is "LANG=C.UTF-8", it seems to have triggered this problem. I got around this by doing SHOP_CURRENCY_LOCALE = 'en_US.UTF-8' in local_settings.py

Never the less, it sounds like something that should be sorted in the installation process.

I'm getting the same issue on fresh installation on Ubuntu 20.04
Locals are set to C by default on my server:

$ locale 
LANG=C.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC=C.UTF-8
LC_TIME=C.UTF-8
LC_COLLATE="C.UTF-8"
LC_MONETARY=C.UTF-8
LC_MESSAGES="C.UTF-8"
LC_PAPER=C.UTF-8
LC_NAME=C.UTF-8
LC_ADDRESS=C.UTF-8
LC_TELEPHONE=C.UTF-8
LC_MEASUREMENT=C.UTF-8
LC_IDENTIFICATION=C.UTF-8
LC_ALL=

When I tried to generate locales and set the currency locale to en_US.UTF-8

SHOP_CURRENCY_LOCALE = 'en_US.UTF-8'

I got:

Invalid currency locale specified for SHOP_CURRENCY_LOCALE: 'en_USA.UTF-8'

For some reason my system had locale as

en_US.utf8

I've played with multiple django based software installation but never seen this type of error. I guess it's something that should be handled by the installation process as @peterkmurphy suggested.

[henri-hulski]

If you want to use a locale in Cartridge it has to be installed in the system.
Don’t know what happened here but the locale en_USA.utf8 doesn't exists. Correct is en_US.utf8.

[damascene]

I didn't want to specify any local, I mean I just want it to get Cartridge to run but the default configurations didn't work for me.

[henri-hulski]

As I recall locale C doesn't work for some reason. But I need to research for the exact issue.
