渲染视图在模板中包含 Django 位置字段

Question

我正在编写一个应用程序，允许用户使用他在地图中的位置添加和编辑泵站。我已经下载并安装 caioariede/django-location-field

问题是当我渲染没有位置字段的视图时一切正常，但是当我添加它时，我得到 TemplateDoesNotExist 异常错误。

这是我的模板add_station.html:

{% extends "backend/main/base.html" %}
{% load i18n %}
{% load staticfiles %}
{% load forms_tags %}


{% block title %}{{meta_keyword}}{% endblock %}
{% block meta_keywords %}{{meta_keyword}}{% endblock meta_keywords %}
{% block meta_description %}{{meta_description}}{% endblock meta_description %}

{% block dash_title %}
    <i class="ppsmsite  ppsmsite-station-service"></i> {% trans "Station" %}
{% endblock %}

{% block dash_main %}
    {% include "backend/main/snippets/required_fields_infos.html" %}
    {% include "backend/main/snippets/alerts_messages.html" %}

    <div class="col-lg-12">
        <div class="panel panel-default">
            <div class="panel-heading">{% trans "Enregistrer une nouvelle station" %}</div>
            <div class="panel-body">
                <form class="form-horizontal" method="POST" enctype="multipart/form-data">
                    {% csrf_token %}
                    {{form}}
                    <div class="form-group">
                        <div class="col-lg-6">
                            {% form_div_row form.nom_station %}
                        </div>
                        <div class="col-lg-6">
                            {% form_div_row form.telephone %}
                        </div>
                    </div>
                    <div class="form-group">
                       <div class="col-lg-12">
                             {% form_div_row form.location %}

                    </div>
                    <div class="form-group">
                        <div class="col-lg-6">
                            {% form_div_row form.city %}
                        </div>
                        <div class="col-lg-6">
                            {% form_div_row form.photo_station %}
                        </div>
                    </div>
                    <div class="form-group">

                            <button type="submit" class="btn btn-primary"><i class="glyphicon glyphicon-check"></i> {% trans "Enregistrer" %}</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>

{% block add_scripts %}
    {{form.media}}

我的模特：

class Station(models.Model):
    """Station service."""

    OPEN = 1
    CLOSE = 0
    STATUTLIST = (
       (OPEN, _("Ouverte")),
       (CLOSE, _("Fermée")),
    )
    nom_station = models.CharField(
      _('Nom de la station'), max_length=30)
    statut_station = models.CharField(
       _('Ouverte ou fermée'),
    max_length=1,
    choices=STATUTLIST, default=OPEN)
    city = models.ForeignKey(City, verbose_name=_('Ville'))
    location = PlainLocationField(
    based_fields=['city'], zoom=7)
    photo_station = models.ImageField(
       _("Photo"),
       upload_to=utils.photo_file_path,
       storage=utils.photo_storage,
       null=True,
       blank=True,
       )
    telephone = PhoneNumberField(_('Numero de téléphone'), null=True)

我的表格：

class StationForm(forms.ModelForm):
"""Docstring for StationsForm."""

def __init__(self, *args, **kwargs):
    """Form Init."""
    self.request = kwargs.pop('request', None)
    super(StationForm, self).__init__(*args, **kwargs)
    for field in self.fields:
        if self.fields[field] is not None:
            self.fields[field].widget.attrs['class'] = 'form-control'

class Meta:
    """Docstring for StationForm meta."""

    model = sitemodels.Station
    fields = [
        'telephone',
        'photo_station', 'location', 'city', 'nom_station']

我的看法：

def add_station_view(request, station_id=None):
"""Ajout et modification d'une station."""
template_name = "backend/main/add_station.html"
args = {}
args.update(csrf(request))

args['meta_keyword'] = args['home_title'] = _('Station')
args['meta_description'] = _('Création d\'une nouvelle station.')

if station_id is not None:
    args['cobject'] = get_object_or_404(
        sitemodels.Station, id=station_id)
    args['meta_description'] = _(
        'Editer %s' % (args['cobject'].get_nom_station()))
    form = siteforms.StationForm(
        request=request,
        instance=args['cobject']
    )

if request.method == 'POST':
    if 'cobject' in args and form.has_changed():
        form = siteforms.StationForm(
            request.POST,
            request=request,
            instance=args['cobject'])
        args['updated'] = True
    else:
        new_station = sitemodels.Station()
        form = siteforms.StationForm(

            instance=new_station)
    if form.is_valid():
        obj = form.save(commit=False)
        obj.save()
        if 'updated' in args:
            messages.success(request, STDUMSG)
        else:
            obj.cree_parking()
            obj.cree_catalogue()
            messages.success(
                request, _('Nouvelle station ajoutée'))
        if 'save_and_add_another' in request.POST:
            return HttpResponseRedirect(
                reverse(
                    'ppsmsite:addstation',
                    current_app=request.resolver_match.namespace,
                )
            )
        return HttpResponseRedirect(
            reverse(
                'ppsmsite:liststatio',
                current_app=request.resolver_match.namespace,
            )
        )
else:
    if 'cobject' not in args:
        form = siteforms.StationForm(request=request)
args['form'] = form
return render_to_response(
    template_name,
    args,
    context_instance=RequestContext(request)
)

这是我在尝试呈现视图时遇到的错误：

Django tried loading these templates, in this order:

拜托，我需要帮助！

当 geodjango 拥有您需要的一切并且非常易于使用时，为什么您需要使用第三方库？

您的位置字段最好以 PointField 开头。

from django.contrib.gis.db import models
class Station(models.Model):

    ...
    ...
    location = PointField()
    ...
    objects = models.GeoManager()

现在您可以访问 vase geodjango api 并允许您执行查询以找出用户附近的泵站等。示例：

https://docs.djangoproject.com/en/1.9/ref/contrib/gis/geoquerysets/#distance-lt

Station.objects.filter(poly__distance_lt=(point, D(m=5)))

渲染视图在模板中包含 Django 位置字段
