Django-Countries: wrong sorting in translated choices (but works in the admin)

问题

I use Django Countries like the following. In my view it seems to order the select items according to the english original values (e.g. Deutschland will be found under G (=Germany)) but in the admin the values are ordered according to the current language. This isn't done by JavaScript (I tried it by disabling JS). I have no idea how to fix this. Versions: Django 1.5.5, Django Countries 2.1.2

models.py

from django_countries.fields import CountryField
class MyModel(ModelSubClass):
    country = CountryField(_('country'), blank=True)
    #...

class MyForm(ModelSubForm):
    class Meta(object):
        model = MyModel
        #...

    def __init__(self, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.fields['country'].required = True
    #...

views.py

class MyCreateView(CreateView):
    model = MyModel
    form_class = MyForm
    # overriding `dispatch`, `get_initial`, `form_valid`, `get_context_data`, `get_success_url`

my_template.html

{% extends "base.html" %}
{% load i18n %}
{% block content %}
<form class="form-horizontal" role="form" method="post" action="">
{% csrf_token %}
{{ form }}
<button type="submit" class="btn btn-success">{% trans 'Submit' %}</button>
</form>
{# ... #}
{% endblock content %}

I can provide more information if needed.

Another thing is that the ordering of countries with non-ASCII capitals is wrong in the admin. But I think this is another issue.

回答1:

Override the choices with the original in MyForm's __init__:

from django_countries import countries
class MyForm(ModelSubForm):
    class Meta(object):
        model = MyModel
        #...

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['country'].choices = [self.fields['country'].choices[0]] + list(countries)
        #...

Use the first item of the choices to keep the empty value (---------).

As far as I understand it the issue is that the choices of a field in models.py are loaded at server start, i.e. once. In the form you can override it on a request basis. The sorting is done by countries (an instance of Countries in the same file).

I'm open for a better solution.

回答2:

Question has been asked similarly before here.

Answer was:

function sort(a, b) {               
        return (a.innerHTML > b.innerHTML) ? 1 : -1;
    };
$('#select_id option').sort(sort).appendTo('#select_id');
