bogtan/django-diplomat

Language and country models for Django derived from the pycountry module.

Diplomat

Diplomat provides Django models for the countries and languages covered by the ISO 3166 and ISO 639 standards, respectively. Diplomat is implemented as a wrapper around a subset of pycountry, and its interface should feel familiar to users of that module.

Installation

Add diplomat to your INSTALLED_APPS, then run the syncdb command, which will create the required language and country models.

Model Usage

Diplomat's field models exactly mirror the attributes of the pycountry database objects that they imitate. In addition to these attributes, custom manager methods are available for some of the objects provided by diplomat.

Languages

The ISOLanguage model is a wrapper around the pycountry.db.Language model.

>>> from diplomat.models import ISOLanguage
>>> aragonese = ISOLanguage.objects.get(alpha2='an')
>>> aragonese.alpha2
u'an'
>>> aragonese.bibliographic
u'arg'
>>> aragonese.terminology
u'arg'
>>> aragonese.name
u'Aragonese'

In addition, it provides a custom model manager.

>>> from diplomat.models import ISOLanguage
>>> all_languages = ISOLanguage.objects.all()
>>> basic_languages = ISOLanguage.objects.basic()
>>> usable_languages = ISOLanguage.objects.usable()
>>> all_languages.count() > usable_languages.count() > basic_languages.count()
True
>>> all([l.alpha2 for l in all_languages])
False
>>> all([l.alpha2 for l in basic_languages])
True
>>> all_languages.filter(terminology='zxx').count()
1
>>> usable_languages.filter(terminology='zxx').count()
0

Countries

The ISOCountry model is a wrapper around the pycountry.db.Country model.

>>> from diplomat.models import ISOCountry
>>> germany = ISOCountry.objects.get(alpha2='DE')
>>> germany.alpha2
u'DE'
>>> germany.alpha3
u'DEU'
>>> germany.numeric
u'276'
>>> germany.name
u'Germany'
>>> germany.official_name
u'Federal Republic of Germany'
