geodjango

问题 I have some users registered in my Django app and I want to simply be able to figure out the distance, geographically, between two users based on their zip code and then sort a list based on that. I would imagine this functionality isn't built into Django. I was looking at some options and stumbled across geodjango which seems like it might be overkill for what my needs are. 回答1: Following tcarobruce's suggestion, here is my above comment as an answer: The Zip Code Database Project has a

问题 I am trying to enable testing on a brand new Django app. It has to run geometry tests. My Postgres installation in Postgres.app (with Postgis 2), my default database runs just fine (no problems with Django app syncing, creating, etc), but when I run manage.py test I get an error: django.db.utils.ProgrammingError: type "geography" does not exist LINE 4: "geom" geography(GEOMETRY,4326) NOT NULL Full errors: https://gist.github.com/dyve/11dcd455aa5a25628773 I know that Django creates a Postgres

问题 Django v1.11.5 I'm trying to install GeoDjango to play around with GoogleMaps. I installed PostgreSQL app for MAC and installed pip install psycopg2 . I also used home-brew to install GDAL. Edited settings.py to add: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'djangodb', 'USER': 'admin', 'PASSWORD': '', 'HOST': 'localhost', 'PORT': '5432', } } However, when I run python manage.py migrate I get: AttributeError: 'DatabaseOperations' object has no attribute

问题 Does anyone have any experience setting up Amazon Elastic Beanstalk with PostGIS (so that I can take advantage of Geodjango)? There are a number of features that the default setup (RDS, featuring MySQL) does not currently support out of box: 1. PostgreSQL + PostGIS 2. The ability to install C/C++ libraries such as GEOS and Proj.4 Thanks in advance 回答1: If you want to use geodjango with Amazon Elastic Beanstalk you need to create a custom AMI where you can install PostGIS and then point your

问题 I have data in geojson format. Here is my data : { "type" : "FeatureCollection", "features" : [ { "type" : "Feature", "properties" : { "year" : 2015, "season" : "rabbi", "crop" : "banana", "district" : "pune", "taluka" : "haveli", "circle" : "uralikanchan", "farmer" : 100 }, "geometry" : { "type" : "Polygon", "coordinates" : [ [ 74.129992, 18.505494 ], [ 74.129047, 18.505494 ], [ 74.128275, 18.504436 ], [ 74.127588, 18.503052 ], [ 74.114456, 18.498331 ], [ 74.113941, 18.498331 ], [ 74.112482,

问题 I have data in my Postgres DB which are in 31277 projection. Anyway, I am using Leaflet map to show them with Geodjango. Right now, my data are moved somewhere down in the map, so I need to change the projection of the Leaflet map. In documentation (http://django-leaflet.readthedocs.io/en/latest/advanced.html) is written just to add SRID attribute to LEAFLET_CONFIG variable, which I did. Like here: LEAFLET_CONFIG = { 'DEFAULT_ZOOM': 13, 'MIN_ZOOM': 2, 'MAX_ZOOM': 18, 'SRID':31277 } But after

问题 Im trying to use Django with Geodjango , I followed all documentation steps, but still got this error when trying to make migrations: OSError: [WinError 127] : The specified procedure could not be found The models.py is correct, I'm using from geodjango site, and this is my settings.py import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

问题 I am trying to retrieve some posts depending on their proximity geographically. As you can see in the code I am using GeoDjango and the code is executed within a view. The issue is that the distance filter seems to be completely disregarded. When I check the distances on the queryset I get the expected distances (1m and 18km) but the 18km post should not have been retrieved. def get(self, request, format=None): latlon=request.query_params pnt = GEOSGeometry('SRID=28992;POINT(%s %s)'%(latlon[

问题 I'm trying to annotate a queryset of Station s with the id of the nearest neighbouring Station using Django 2.0.3 and PostGIS (GeoDjango) functions. Simplified Station model: class Station(models.Model): name = models.CharField(max_length=128) location = models.PointField() objects = StationQuerySet.as_manager() The problem I'm having is trying to compute the closest distance, which involves annotating a subquery which refers to the location in the outer queryset. from django.db.models import
