django-countries下拉不显示

This is the third iteration of this question as errors have been solved(在少数人的感谢帮助下)。为了避免混淆到底发生了什么,我觉得有必要重新发布更新的细节。

我正在使用Django 1.6.4。

我正在尝试将django-countries application与Django一起使用,但下拉列表未显示。我没有收到任何错误,但下面的survey.html页面未显示ISO 3166-1国家/地区列表的预期下拉列表。

我通过pip在项目的虚拟环境中安装了django-countries 2.1.2。它已添加到已安装的应用

    sex = SexChoice()

    country = Person()

    return render(request, 'survey.html', {
                                           'age': age,

survy.html

<html> 
    <body>

        <h1>Experiment Survey</h1>

            <form action="" method="post">
                {% csrf_token %}
                <h3>What age are you?</h3>
                    {{age.as_p}}

                <h3>What sex are you?</h3>
                    {{sex.as_p}}

                <h3>What is your current relationship status?</h3>
                    {{relationship.as_p}}

                <h3>What country are you from?</h3>

                    {{country.as_p}}

                <input type="submit" value="Submit" />               
            </form>
    </body>
</html>

我认为这会给我一个country.as_p下拉但我什么也看不见。我没有任何错误。

提前致谢。

According to the documentation,模块中有一个2元组的元组可以填充你的字段:

  

从Python获取国家/地区

     

使用django_countries.countries对象实例作为ISO 3166-1国家/地区代码和名称的迭代器(按名称排序)。

所以以下内容应该有效:

from django.db import models
from django_countries.fields import CountryField
from django_countries import countries

class Person(models.Model):
    country = CountryField(choices=list(countries))

    def __unicode__(self):
        return self.country

编辑:经过讨论,我通过阅读过快的OP代码完全搞砸了。实际上,您需要创建一个Form,而不是直接在模板中使用您的模型:

class SurveyForm(forms.Form):
    age = forms.CharField()
    sex = forms.CharField()
    relationship = forms.CharField()
    country = forms.CountryField(choices=list(countries))

#####

def survey(request):
    form = SurveyForm()

    return render(request, 'survey.html', {'form': form})


#####

My whole form:
{{ form.as_p }}

正如我在聊天中所说,further explication are available in the documentation

您需要以下表格:

class SurveyForm(forms.Form):
    age = forms.CharField()
    sex = forms.CharField()
    relationship = forms.CharField()
    country = forms.ChoiceField(choices=list(countries))

不需要在表单类中使用ChoiceField()。 CountryField()用于模型。
