CountryField

A country field for Django models that provides all ISO 3166-1 countries as choices.

CountryField is based on Django's CharField, providing choices corresponding to the official ISO 3166-1 list of countries (with a default max_length of 2).

Consider the following model using a CountryField:

from django.db import models
from django_countries.fields import CountryField

class Person(models.Model):
    name = models.CharField(max_length=100)
    country = CountryField()

Any Person instance will have a country attribute that you can use to get details of the person's country:

>>> person = Person(name='Chris', country='NZ')
>>> person.country
Country(code='NZ')
>>> person.country.name
'New Zealand'
>>> person.country.flag
'/static/flags/nz.gif'

This object (person.country in the example) is a Country instance, which is described below.

Use blank_label to set the label for the initial blank choice shown in forms:

country = CountryField(blank_label='(select country)')

Multi-choice

This field can also allow multiple selections of countries (saved as a comma separated string). The field will always output a list of countries in this mode. For example:

class Incident(models.Model):
    title = models.CharField(max_length=100)
    countries = CountryField(multiple=True)

>>> for country in Incident.objects.get(title='Pavlova dispute').countries:
...     print(country.name)
Australia
New Zealand

The `Country` object

An object used to represent a country, instanciated with a two character country code, three character code, or numeric code.

It can be compared to other objects as if it was a string containing the country code and when evaluated as text, returns the country code.

name

Contains the full country name.

flag

Contains a URL to the flag. If you page could have lots of different flags then consider using flag_css instead to avoid excessive HTTP requests.

flag_css

Output the css classes needed to display an HTML element as the correct flag from within a single sprite image that contains all flags. For example:

<link rel="stylesheet" href="{% static 'flags/sprite.css' %}">
<i class="{{ country.flag_css }}"></i>

For multiple flag resolutions, use sprite-hq.css instead and add the flag2x, flag3x, or flag4x class. For example:

<link rel="stylesheet" href="{% static 'flags/sprite-hq.css' %}">
Normal: <i class="{{ country.flag_css }}"></i>
Bigger: <i class="flag2x {{ country.flag_css }}"></i>

You might also want to consider using aria-label for better accessibility:

<i class="{{ country.flag_css }}"
    aria-label="{% blocktrans with country_code=country.code %}
        {{ country_code }} flag
    {% endblocktrans %}"></i>

unicode_flag

A unicode glyph for the flag for this country. Currently well-supported in iOS and OS X. See https://en.wikipedia.org/wiki/Regional_Indicator_Symbol for details.

code

The two letter country code for this country.

alpha3

The three letter country code for this country.

numeric

The numeric country code for this country (as an integer).

numeric_padded

The numeric country code as a three character 0-padded string.

`CountrySelectWidget`

A widget is included that can show the flag image after the select box (updated with JavaScript when the selection changes).

When you create your form, you can use this custom widget like normal:

from django_countries.widgets import CountrySelectWidget

class PersonForm(forms.ModelForm):
    class Meta:
        model = models.Person
        fields = ('name', 'country')
        widgets = {'country': CountrySelectWidget()}

Pass a layout text argument to the widget to change the positioning of the flag and widget. The default layout is:

'{widget}<img class="country-select-flag" id="{flag_id}" style="margin: 6px 4px 0" src="{country.flag}">'

Custom forms

If you want to use the countries in a custom form, use the model field's custom form field to ensure the translatable strings for the country choices are left lazy until the widget renders:

from django_countries.fields import CountryField

class CustomForm(forms.Form):
    country = CountryField().formfield()

Use CountryField(blank=True) for non-required form fields, and CountryField(blank_label='(Select country)') to use a custom label for the initial blank option.

You can also use the CountrySelectWidget as the widget for this field if you want the flag image after the select box.

Get the countries from Python

Use the django_countries.countries object instance as an iterator of ISO 3166-1 country codes and names (sorted by name).

For example:

>>> from django_countries import countries
>>> dict(countries)['NZ']
'New Zealand'

>>> for code, name in list(countries)[:3]:
...     print("{name} ({code})".format(name=name, code=code))
...
Afghanistan (AF)
Åland Islands (AX)
Albania (AL)

Country names are translated using Django's standard ugettext. If you would like to help by adding a translation, please visit https://www.transifex.com/projects/p/django-countries/

Template Tags

If you have your country code stored in a different place than a CountryField you can use the template tag to get a Country object and have access to all of its properties:

{% load countries %}
{% get_country 'BR' as country %}
{{ country.name }}

If you need a list of countries, there's also a simple tag for that:

{% load countries %}
{% get_countries as countries %}
<select>
{% for country in countries %}
    <option value="{{ country.code }}">{{ country.name }}</option>
{% endfor %}
</select>

Customization

Customize the country list

Country names are taken from the official ISO 3166-1 list. If your project requires the use of alternative names, the inclusion or exclusion of specific countries then use the COUNTRIES_OVERRIDE setting.

A dictionary of names to override the defaults.

Note that you will need to handle translation of customised country names.

Setting a country's name to None will exclude it from the country list. For example:

from django.utils.translation import ugettext_lazy as _

COUNTRIES_OVERRIDE = {
    'NZ': _('Middle Earth'),
    'AU': None
}

If you have a specific list of countries that should be used, use COUNTRIES_ONLY:

COUNTRIES_ONLY = ['NZ', 'AU']

or to specify your own country names, use a dictionary or two-tuple list (string items will use the standard country name):

COUNTRIES_ONLY = [
    'US',
    'GB',
    ('NZ', _('Middle Earth')),
    ('AU', _('Desert')),
]

Show certain countries first

Provide a list of country codes as the COUNTRIES_FIRST setting and they will be shown first in the countries list (in the order specified) before all the alphanumerically sorted countries.

If you want to sort these initial countries too, set the COUNTRIES_FIRST_SORT setting to True.

By default, these initial countries are not repeated again in the alphanumerically sorted list. If you would like them to be repeated, set the COUNTRIES_FIRST_REPEAT setting to True.

Finally, you can optionally separate these 'first' countries with an empty choice by providing the choice label as the COUNTRIES_FIRST_BREAK setting.

Customize the flag URL

The COUNTRIES_FLAG_URL setting can be used to set the url for the flag image assets. It defaults to:

COUNTRIES_FLAG_URL = 'flags/{code}.gif'

The URL can be relative to the STATIC_URL setting, or an absolute URL.

The location is parsed using Python's string formatting and is passed the following arguments:

code

code_upper

For example: COUNTRIES_FLAG_URL = 'flags/16x10/{code_upper}.png'

No checking is done to ensure that a static flag actually exists.

Alternatively, you can specify a different URL on a specific CountryField:

class Person(models.Model):
    name = models.CharField(max_length=100)
    country = CountryField(
        countries_flag_url='//flags.example.com/{code}.png')

Single field customization

To customize an individual field, rather than rely on project level settings, create a Countries subclass which overrides settings.

To override a setting, give the class an attribute matching the lowercased setting without the COUNTRIES_ prefix.

Then just reference this class in a field. For example, this CountryField uses a custom country list that only includes the G8 countries:

from django_countries import Countries

class G8Countries(Countries):
    only = [
        'CA', 'FR', 'DE', 'IT', 'JP', 'RU', 'GB',
        ('EU', _('European Union'))
    ]

class Vote(models.Model):
    country = CountryField(countries=G8Countries)
    approve = models.BooleanField()

Django Rest Framework

Django Countries ships with a CountryFieldMixin to make the CountryField model field compatible with DRF serializers. Use the following mixin with your model serializer:

from django_countries.serializers import CountryFieldMixin

class CountrySerializer(CountryFieldMixin, serializers.ModelSerializer):

    class Meta:
        model = models.Person
        fields = ('name', 'email', 'country')

This mixin handles both standard and multi-choice country fields.

Django Rest Framework field

For lower level use (or when not dealing with model fields), you can use the included CountryField serializer field. For example:

from django_countries.serializer_fields import CountryField

class CountrySerializer(serializers.Serializer):
    country = CountryField()

You can optionally instantiate the field with the countries argument to specify a custom Countries instance.

REST output format

By default, the field will output just the country code. If you would rather have more verbose output, instantiate the field with country_dict=True, which will result in the field having the following output structure:

{"code": "NZ", "name": "New Zealand"}

Either the code or this dict output structure are acceptable as input irregardless of the country_dict argument's value.

OPTIONS request

When you request OPTIONS against a resource (using the DRF metadata support) the countries will be returned in the response as choices:

OPTIONS /api/address/ HTTP/1.1

HTTP/1.1 200 OK
Content-Type: application/json
Allow: GET, POST, HEAD, OPTIONS

{
"actions": {
  "POST": {
    "country": {
    "type": "choice",
    "label": "Country",
    "choices": [
      {
        "display_name": "Australia",
        "value": "AU"
      },
      [...]
      {
        "display_name": "United Kingdom",
        "value": "GB"
      }
    ]
  }
}
