How to provide a default value for the country field

If you want to provide a default value for the IAddress country field, you can provide an ComputedWidgetAttribute adapter like so:

from zope.component import provideAdapter
from z3c.form.widget import ComputedWidgetAttribute
from collective.address.behaviors import IAddress

DEFAULT_COUNTRY = "040"  # Austria
provideAdapter(ComputedWidgetAttribute(
    lambda data: DEFAULT_COUNTRY,
    field=IAddress['country']), name='default')

The country code must be the numeric ISO 3166-1 code as a string. You can find the list of codes here: https://en.wikipedia.org/wiki/ISO_3166-1_numeric

If you want to play with the country codes in a Python shell, you can use the pycountry package like so:

>>> import pycountry
>>> austria = pycountry.countries.get(numeric='040')
>>> austria
Country(alpha_2='AT', alpha_3='AUT', flag='🇦🇹', name='Austria', numeric='040', official_name='Republic of Austria')
>>> spain = pycountry.countries.get(alpha_2='ES')
>>> spain
Country(alpha_2='ES', alpha_3='ESP', flag='🇪🇸', name='Spain', numeric='724', official_name='Kingdom of Spain')

You can install pycountry via pip:

pip3 install pycountry
