Django: Country drop down list?

问题

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?

回答1:

Check out "choices" parameter of a CharField.

You might also want to take a look at django-countries.

回答2:

Django Countries

from django_countries.fields import CountryField

class Foo(models.Model):
    country = CountryField()

回答3:

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.

Django Countries

from django_countries.countries import COUNTRIES

class CountryForm(forms.Form):
      country= forms.ChoiceField(COUNTRIES)

Two low mantained projects:

http://code.google.com/p/django-countries/

https://github.com/strange/django-country-utils

Two snippets:

http://djangosnippets.org/snippets/494/

http://djangosnippets.org/snippets/1476/

For now, I am going for a snippet.

Here is a nice library with countries (and not only): pycountry

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: Writing custom django-admin commands

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

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

from django_countries.data import COUNTRIES

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

回答8:

Put them in the database is a better way. Convenient to management.

回答9:

Link to package : django-countries
If looking for how to do it in forms :

$ pip install django-countries

>>> from django_countries.data import COUNTRIES

>>> Country = forms.ChoiceField(choices = sorted(COUNTRIES.items()))

Here is the solution:

from django_countries.fields import CountryField

class Foo(TimeStampedModel):

    country = CountryField()

回答11:

I solved it by using multiple=True:

from django_countries.fields import CountryField    

class UserProfile(models.Model):
    countries = CountryField(multiple=True)
