Python Charfield没有以django的形式出现

我正在创建一个使用django userena的基本django站点。通过在my forms.py上创建EditProfileFormExtra类，我正在覆盖默认的注册表单。然而，我发现了一个非常奇怪的问题。“纬度”和“经度”字段不显示。更改字段的名称似乎会使它们显示出来，但将它们命名为“lat”或“lation”和“long”或“longitude”会使它们显示出来？！为什么会这样

from django import forms
from django.utils.translation import ugettext_lazy as _
from userena.forms import SignupForm
from userena.forms import EditProfileForm
from Couches.models import Location
from django.core.validators import RegexValidator


# Code adapted from: http://django-userena.readthedocs.org/en/latest/faq.html#how-do-i-add-extra-fields-to-forms
class SignupFormExtra(SignupForm):
    first_name = forms.CharField(label=_(u'First name'),
                                 max_length=30,
                                 required=True)
    last_name = forms.CharField(label=_(u'Last name'),
                                max_length=30,
                                required=True)
    latitude = forms.CharField(label=_(u'Latitude'),
                               max_length=30,
                               required=False,
                               validators=[RegexValidator(regex='^[-+]?[0-9]*\.?[0-9]+$'),])
    longitude = forms.CharField(label=_(u'Longitude'),
                                max_length=30,
                                required=False,
                                validators=[RegexValidator(regex='^[-+]?[0-9]*\.?[0-9]+$'),])

    def save(self):
        # First save the parent form and get the user.
        new_user = super(SignupFormExtra, self).save()
        new_user.first_name = self.cleaned_data['first_name']
        new_user.last_name = self.cleaned_data['last_name']
        new_user.save()

        Location.objects.create(available=True,
                                user=new_user,
                                latitude=self.cleaned_data['latitude'],
                                longitude=self.cleaned_data['longitude'])

        return new_user


class EditProfileFormExtra(EditProfileForm):
    description = forms.CharField(label=_(u'Description'),
                                  max_length=300,
                                  required=False,

    contact_information = forms.CharField(label=_(u'Contact Information'),
                                          max_length=300,

    graduation_year = forms.CharField(label=_(u'Graduation Year'),
                                      max_length=4,
                                      required=False,
                                      validators=[RegexValidator(regex='^\d{4}$'), ])
    address = forms.CharField(label=_(u'Contact Information'),
                                          max_length=100,
                                          required=False)
    # BUG: the two fields below do not appear on the form
    latitude = forms.CharField(label=_(u'Latitude'),
                            max_length=30,
                            required=False,
                            validators=[RegexValidator(regex='^[-+]?[0-9]*\.?[0-9]+$'), ])
    longitude = forms.CharField(label=_(u'lon'),
                                max_length=30,
                                required=False,
                                validators=[RegexValidator(regex='^[-+]?[0-9]*\.?[0-9]+$'), ])

    def save(self, force_insert=False, force_update=False, commit=True):
        profile = super(EditProfileFormExtra, self).save()
        profile.description = self.cleaned_data['description']
        profile.contact_information = self.cleaned_data['contact_information']
        profile.graduation_year = self.cleaned_data['graduation_year']

        location = Location.objects.get(user = profile.user)
        if(location):
          location.latitude = self.cleaned_data['latitude']
          location.longitude = self.cleaned_data['longitude']
          location.save()

        return profile

这是显示表单的模板：

{% extends 'base.html' %}
{% load i18n %}
{% load url from future %}

{% block title %}{% trans "Account setup" %}{% endblock %}

{% block content_title %}<h2>{% blocktrans with profile.user.username as username %}Account &raquo; {{ username }}{% endblocktrans %}</h2>{% endblock %}

{% block content %}

Edit your very own profile.

<form action="" enctype="multipart/form-data" method="post">
  <ul id="box-nav">
    <li class="first"><a href="{% url 'userena_profile_detail' user.username %}"><span>{% trans 'View profile' %}</span></a></li>
    <li class="selected"><a href="{% url 'userena_profile_edit' user.username %}">{% trans "Edit profile" %}</a></li>
    <li><a href="{% url 'userena_password_change' user.username %}">{% trans "Change password" %}</a></li>
    <li class="last"><a href="{% url 'userena_email_change' user.username %}">{% trans "Change email" %}</a></li>
  </ul>
  {% csrf_token %}
  <fieldset>
    <legend>{% trans "Edit Profile" %}</legend>
    {{ form.as_p }}
  </fieldset>
  <input type="submit" value="{% trans "Save changes" %}" />
</form>
{% endblock %}

这是来自django userena（）的视图

让我们看看插入表单的模板代码。谢谢，我刚刚在消息中添加了模板代码。请显示您的模型。添加了模型，谢谢。我想我们还需要查看视图。此外，除了Stackoverflow之外，也许还应该在代码审查站点上展示此代码？除了修复你所经历的怪异行为之外，还有很多反馈需要提供。
