django-metasettings 0.1

Installation

1. To install it, simply

   pip install django-metasettings

2. Add ‘metasettings’ to your INSTALLED_APPS

   INSTALLED_APPS = (
       'metasettings',
   )

If you want to install the dashboard to allow your users to select a language and a currency you will have to install urls from metasettings like so

# urls.py

from django.conf.urls.defaults import patterns, include

urlpatterns = patterns(
    '',
    (r'^', include('metasettings.urls'))
)

You can add your proper stylesheet to this dashboard view and have this kind of result:

Usage

To import current currency rates, run

python manage.py sync_rates --app_id=openexchangesratesappid

To import currency rates in a date range, run

python manage.py sync_rates --app_id=openexchangesratesappid --date_start=2011-10-01 --date_end=2013-10-01

It will import for each months between the two dates the currency rates.

If you can to convert an amount from on currency to another

from metasettings.models import convert_amount

convert_amount('EUR', 'USD', 15)  # ~20 euros

By default it will return a full decimal, if you want a converted integer

from metasettings.models import convert_amount

convert_amount('EUR', 'USD', 15, ceil=True)  # ~20 euros

To retrieve the currency with a client IP Address:

from metasettings.models import get_currency_from_ip_address

get_currency_from_ip_address('78.192.244.8') # EUR

We are using GeoIP which gives you the ability to retrieve the country and then we are linking the country to an existing currency.

So don’t forget to import a fresh GeoIP database and be sure to have GEOIP_PATH in your settings.

We recommend to use django-geoip-utils which provides some helpers to manipulate GeoIP API.
