A Django application that provides country choices for use with forms, flag
icons static files, and a country field for models.

Country names are translated using Django’s standard gettext. If you would
like to help by adding a translation, please visit

Installation

  1. pip install django-countries

    For more accurate sorting of translated country names, install it with the
    optional pyuca_ package:

    pip install django-countries[pyuca]

  2. Add django_countries to INSTALLED_APPS

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:

… code:: python

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:

… code:: python

>>> 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:

… code:: python

country = CountryField(blank_label="(select country)")

You can filter using the full English country names in addition to country
codes, even though only the country codes are stored in the database by using
the queryset lookups contains, startswith, endswith, regex, or
their case insensitive versions. Use __name or __iname for the
exact/iexact equivalent:

… code:: python

>>> Person.objects.filter(country__name="New Zealand").count()
1
>>> Person.objects.filter(country__icontains="zealand").count()
1

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:

… code:: python

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

By default, countries are stored sorted for data consistency, and any
duplicates are removed. These behaviours can be overridden by using the field
arguments multiple_sort=False and multiple_unique=False respectively.

The Country object

An object used to represent a country, instantiated 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:

… code:: jinja

<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:

… code:: jinja

<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:

… code:: jinja

<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.

ioc_code
The three letter International Olympic Committee country code.

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:

… code:: python

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:

… code:: python

'{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:

… code:: python

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:

… code:: python

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

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

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:

… code:: jinja

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

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

… code:: jinja

{% 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, with some country
names being replaced with their more common usage (such as “Bolivia” instead
of “Bolivia, Plurinational State of”).

To retain the official ISO 3166-1 naming for all fields, set the
COUNTRIES_COMMON_NAMES setting to False.

If your project requires the use of alternative names, the inclusion or
exclusion of specific countries then set the COUNTRIES_OVERRIDE setting to
a dictionary of names which override the defaults. The values can also use a
more complex dictionary format_.

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:

… code:: python

from django.utils.translation import gettext_lazy as _

COUNTRIES_OVERRIDE = {
    "NZ": _("Middle Earth"),
    "AU": None,
    "US": {
        "names": [
            _("United States of America"),
            _("America"),
        ],
    },
}

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

… code:: python

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):

… code:: python

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:

… code:: python

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:

… code:: python

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:

… code:: python

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()

Complex dictionary format

For COUNTRIES_ONLY and COUNTRIES_OVERRIDE, you can also provide a
dictionary rather than just a translatable string for the country name.

The options within the dictionary are:

name or names (required)
Either a single translatable name for this country or a list of multiple
translatable names. If using multiple names, the first name takes preference
when using COUNTRIES_FIRST or the Country.name.

alpha3 (optional)
An ISO 3166-1 three character code (or an empty string to nullify an existing
code for this country.

numeric (optional)
An ISO 3166-1 numeric country code (or None to nullify an existing code
for this country. The numeric codes 900 to 999 are left available by the
standard for user-assignment.

ioc_code (optional)
The country’s International Olympic Committee code (or an empty string to
nullify an existing code).

Country object external plugins

Other Python packages can add attributes to the Country_ object by using entry
points in their setup script.

Country: The Country object

For example, you could create a django_countries_phone package which had a
with the following entry point in the setup.py file. The entry point name
(phone) will be the new attribute name on the Country object. The attribute
value will be the return value of the get_phone function (called with the
Country instance as the sole argument).

… code:: python

setup(

entry_points={
“django_countries.Country”: “phone = django_countries_phone.get_phone”
},

)

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:

… code:: python

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:

… code:: python

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.

Countries: Single field customization

REST output format
^^^^^^^^^^^^^^^^^^

By default, the field will output just the country code. To output the full
country name instead, instantiate the field with name_only=True.

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:: json

{"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:

… code:: text

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"
      }
    ]
  }
}

… _metadata support: http://www.django-rest-framework.org/api-guide/metadata/

GraphQL

A Country graphene object type is included that can be used when generating
your schema.

… code:: python

import graphene
from graphene_django.types import DjangoObjectType
from django_countries.graphql.types import Country

class Person(ObjectType):
    country = graphene.Field(Country)

    class Meta:
        model = models.Person
        fields = ["name", "country"]

The object type has the following fields available:

  • name for the full country name
  • code for the ISO 3166-1 two character country code
  • alpha3 for the ISO 3166-1 three character country code
  • numeric for the ISO 3166-1 numeric country code
  • iocCode for the International Olympic Committee country code
