Ended up using the below snippet which basically defines a tuple of tuples of two character country codes. Additionally it defines a custom field type called CountryField and defaults the choices parameter to the above defined tuple. This automatically gets rendered as a drop down list.

As previous answers have stated, there is a <code>CountryField</code> in <code>django-countries</code>. This is a model field. 

If a form field is needed in a plain form (not model form), in <code>django-countries</code> v3.x (definitely tested in 3.3) the following can be used:

<pre><code>from django_countries.data import COUNTRIES

class MyForm(forms.Form):
 country = forms.ChoiceField(sorted(COUNTRIES.items()))

Here is a nice library with countries (and not only): <a href="http://pypi.python.org/pypi/pycountry" rel="nofollow" title="pycountry">pycountry</a>

Its main advantage is that it is a wrapper around Debian package pkg-isocodes (thus can updates automatically with it) compared to hard-coded countries in other solutions. It also has translations.

So if new country appears or existing countries will be merged together you do not need to change your code.

I found it useful to use this library and create a simple Django app with model Country for example

Then you can populate and keep up-to-date your 'country' table by means of custom django-admin command as described here: <a href="http://docs.djangoproject.com/en/dev/howto/custom-management-commands/" rel="nofollow">Writing custom django-admin commands</a>

If you are extending forms.Form class then you have to specify .formfield right after your Countryfield and then specify your attributes in formfield() parameter.

<pre><code>from django_countries.fields import CountryField
class CheckOutForm(forms.Form):
 country = CountryField().formfield()
</code></pre>

But if you are extending from models.Model class then defining Coutryfield is enough.

<pre><code>from django_countries.fields import CountryField
 class CheckOutForm(models.Model):
 country = CountryField()
</code></pre>

I guess, instead of trying with models fields such as <code>ChoiceField</code> or <code>CharField</code> and passing 'choices' as a parameter which contains list of countries as tuple values inside the list created outside in the models.py, Django has compact library to work with selecting country while filling the form.

If you just want to have a country ChoiceField without installing <a href="https://pypi.org/project/django-countries/" rel="nofollow noreferrer">django-choices</a> you can create an extra file which holds a tuple with all choices from the <a href="http://geohack.net/gis/wikipedia-iso-country-codes.csv" rel="nofollow noreferrer">Wikipedia Iso Country Codes</a>:
<pre><code>import csv


# Get the file from: &quot;http://geohack.net/gis/wikipedia-iso-country-codes.csv&quot;
with open(&quot;wikipedia-iso-country-codes.csv&quot;) as f:
 file = csv.DictReader(f, delimiter=',')
 country_names = [line['English short name lower case'] for line in file]

# Create a tuple with the country names
with open(&quot;country_names.py&quot;, 'w') as f:
 f.write('COUNTRY_CHOICES = (\n')
 for c in country_names:
 f.write(f' (&quot;{c}&quot;, &quot;{c}&quot;),\n')
 f.write(')')
</code></pre>
The created country_names.py file looks something like this:
<pre><code>COUNTRY_CHOICES = (
 (&quot;Afghanistan&quot;, &quot;Afghanistan&quot;),
 (&quot;Åland Islands&quot;, &quot;Åland Islands&quot;),
 (&quot;Albania&quot;, &quot;Albania&quot;),
 (&quot;Algeria&quot;, &quot;Algeria&quot;),
 (&quot;American Samoa&quot;, &quot;American Samoa&quot;),
 ...
)
</code></pre>
You can then use COUNTRY_CHOICES in your form like this:
<pre><code>from django import forms
from country_names import COUNTRY_CHOICES


class CountryForm(forms.Form):
 country= forms.ChoiceField(choices=COUNTRY_CHOICES)
</code></pre>

I have a form for address information. One of the fields is for the address country. Currently this is just a textbox. I would like a drop down list (of ISO 3166 countries) for this. I'm a django newbie so I haven't even used a Django Select widget yet. What is a good way to do this?

Hard-code the choices in a file somewhere? Put them in the database? In the template?

我有一张地址信息的表格。其中一个字段用于地址国家/地区。目前这只是一个文本框。我想要一个下拉列表( ISO 3166国家)为此。我是django新手，所以我甚至还没有使用过Django Select小部件。做这件事的好方法是什么？是否将选择硬编码到某个文件中？把它们放到数据库里？在模板中？
