Re: [django-oscar] NoneType object has no attribute currency_formats

[David Winterbottom]

This is related to locales.  

It seems Babel (the package Oscar uses for currency formatting) can't find a locale for your system.  It may be worth playing around with Babel in isolation to see if you can recreate the problem when you format a currency.  Maybe you need to configure your OS in some way to provide a locale.

I'm not a Windows user and don't have any experience here.

More broadly, Oscar is aimed at linux, mac users - not windows.  There may well be other problems with running Oscar on Windows.  If it's palatable, I suggest using a linux box to develop on Oscar.  You could use Vagrant (http://vagrantup.com/ [homepage is down right now]) - Oscar ships with a VagrantFile that will provision a virtual machine correctly:

Good luck!

Hi,

First of all many thanks Oscar's developers for making Oscar public. It looks very promising!

I'm in process of switching from PHP to Python and looking for some decent e-commerce framework. At the moment I'm new to Python and Django but have solid background in ASP.NET and PHP. I've installed Sandbox demo app on Windows machine following documentation as close as possible. As there is no 'make' command on Windows I ran appropriate commands from Makefile manually. It seems everything installed smoothly. But after I started server and tried to access homepage I got error (see bellow). Does anybody have some ideas on how to fix it? I'm on Windows XP. Any advice will be appreciated.

Settings of environment variable LANG=ru_RU.UTF-8 helped me. But those
was on linux system.

Thanks. It helped me too. I added environment variable LANG=ru_RU.UTF-8 and babel error is gone.

You are welcome. Just set instead of ru_RU your language and country
codes (en_US or whatever) and maybe another encoding if you are not
using utf8.

I put the following on settings.py

OSCAR_DEFAULT_CURRENCY = 'USD'

OSCAR_CURRENCY_LOCALE = 'en_US'

after that, it works fine for me.

[Maik Hoepfel]

It's not the first time I've run into this issue. I created an issue so that somebody has a closer look: https://github.com/tangentlabs/django-oscar/issues/837

[aamir hussain]

The first error after running the oscar is this error.

But fortunately found a very simple and easy way out .i.e include 

OSCAR_DEFAULT_CURRENCY and  OSCAR_CURRENCY_LOCALE

in your settings. For me it was 

OSCAR_DEFAULT_CURRENCY = 'AED'

OSCAR_CURRENCY_LOCALE = 'ar_AE'

it works fine ,all the error disappeared but the currency symbol is not displayed correctly.

[Izidor Matušov]

Hi Aamir,

I don't know what is the correct symbol to display but in the end, you
end up running this code:

In [1]: from babel.numbers import format_currency

In [2]: format_currency(5.99, currency='AED', locale='ar_AE')
Out[2]: u'\u062f.\u0625.\u200f\xa05\u066b99'

In [3]: print format_currency(5.99, currency='AED', locale='ar_AE')
د.إ.‏ 5٫99

It's displayed differently in the email editor and my terminal (see
attachment)

What is the correct representation of currency for AED?

You might want to play with the OSCAR_CURRENCY_FORMAT which maps into
babel format parameter:

http://babel.pocoo.org/docs/api/numbers/#babel.numbers.format_currency

[Maik Hoepfel]

I've added a default OSCAR_CURRENCY_LOCALE in https://github.com/tangentlabs/django-oscar/commit/0de4e4d0d81f4b1d0ecf2b7a91b0aa1db84c7e88
