Die Renderansicht enthält das Django-Ortsfeld in der Vorlage

Question

Ich schreibe eine App, mit der Benutzer Pumpstationen mit ihrer Position in der Karte hinzufügen und bearbeiten können. Ich habe heruntergeladen und installiert caioariede/django-Location-Feld

das Problem ist, dass, wenn ich die Ansicht ohne Standortfeld machen alles perfekt funktioniert, aber wenn ich es hinzufügen, erhalte ich TemplateDoesNotExist Ausnahmefehler.

dass meine Vorlage add_station.html ist:

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


{% block title %}{{meta_keyword}}{% endblock %}

{% 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> 
     </div> 
    </div> 
{% endblock %} 
{% block add_scripts %} 
    {{form.media}} 
{% endblock add_scripts %} 

Mein Modell:

Bitte ich eine Hilfe benötigen!

Answer 1

Warum brauchen Sie Bibliotheken von Drittanbietern, wenn geodjango alles hat, was Sie brauchen, und es so einfach zu bedienen ist?

Ihr Standort Feld sollte idealerweise ein PointField Beginnen mit.

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

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

Jetzt haben Sie Zugriff auf die Vase geodjango api und ermöglicht es Ihnen, Abfragen durchführen, um herauszufinden, was Pumpstationen nahe an den Benutzer usw. Beispiel:

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

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