I'm trying to display a custom map feature on a GeoDjango map. The geometry is a multipolygon stored in a PostGIS database backend.
And I have trouble to find the correct piece of documentation that explains how to load and add my geometry from the database. This is what my PostGIS contains:
SELECT * FROM aptroomat_worldborder;
This is my model.py equivalent in my GeoDjango project:
from django.contrib.gis.db import models class WorldBorder(models.Model): name = models.CharField(max_length=50) area = models.IntegerField() pop2005 = models.IntegerField('Population 2005') fips = models.CharField('FIPS Code', max_length=2) iso2 = models.CharField('2 Digit ISO', max_length=2) iso3 = models.CharField('3 Digit ISO', max_length=3) un = models.IntegerField('United Nations Code') region = models.IntegerField('Region Code') subregion = models.IntegerField('Sub-Region Code') lon = models.FloatField() lat = models.FloatField() mpoly = models.MultiPolygonField() objects = models.GeoManager() def __str__(self): return self.name This is how I define my form in forms.py:
from django.contrib.gis import forms class WorldBorderForm(forms.Form): world = forms.MultiPolygonField(widget = forms.OSMWidget(attrs = {'map_width': 1024, 'map_height': 600})) And my views.py containing the callback:
from django.shortcuts import render from myproject.forms import WorldBorderForm def index(request): form = WorldBorderForm() context = { 'form': form } return render(request, 'myproject/index.html', context) This is how the result looks including my template, using an OSM base widget:
This is pretty much what I get from reading the GeoDjango documentation and following the GeoDjango tutorial on World Borders.
But the missing piece in the docs is: How to display my geometries from the PostGIS database in my GeoDjango map widget? I can't seem to figure out how to connect both.
Any ideas? Source code is on github.com/donSchoe/sabracta.
