Re: GeometryField.geography = True Syntax Help GIS Model

Hope you got to the bottom of this, and yes I thought your original 
question was pretty direct.

If you haven't worked it out already and are still trying to get this 
working (or if anyone else stumbles across this), then essentially yes you 
would pass in geography=True, just as you would specify max_length=30 or 
any other field property.  The documentation suggests this only works with 
SRID 4326, so you need srid=4326 on your field as well.

 Hello everyone,

 So I've decided for my GeoDjango application I want WGS84 along with a 
 geography database column, rather than geometry.

 I was reading here:

 https://docs.djangoproject.com/en/1.4/ref/contrib/gis/
 model-api/#geography

 GeometryField.geography
  

 If set to True, this option will create a database column of type 
 geography, rather than geometry. Please refer to the geography 
 type
  section 
 below for more details.


 that to set up a new column as geography I had to 
 set GeometryField.geography = True.

 I am unsure of the syntax of how to do this? There was no example 
 given. Or where to properly place this line?

 Here is the model.py file I am working on. If you could tell me where 
 to fit this in that would be great?


 from django.contrib.gis.db import models

 class Artist(models.Model):
 name = models.CharField(max_length=30)
 genre = models.CharField(max_length=30)
 city = models.CharField(max_length=60)
 state = models.CharField(max_length=30)
 country = models.CharField(max_length=50)
 website = models.URLField()
 objects = models.GeoManager()

 def __unicode__(self):
return self.name



 Thanks so much,

 JJ

Re: GeometryField.geography = True Syntax Help GIS Model

2012-11-03 Thread JJ Zolper 
Thanks for the reply.

I actually already have PostgreSQL.

So my question was pretty direct, or so I thought.

I'll try and spell this out again. So if I want to create a column in my 
database with type "geography" is this the syntax:

mpoly = models.MultiPolygonField(geography=true)

I cannot find an single example where we specify that we want the geography 
type to be used instead of using geometries.

All I need to know is if that is right? Is it a capitalized "true" so 
"TRUE" ?

Thanks so much,

JJ

Re: GeometryField.geography = True Syntax Help GIS Model

2012-11-02 Thread Christiano Anderson 
First of all, you have to create a geo database. Postgis (a PostgreSQL
extension) is the best choice.

After that, you have to define some geography fields and import your data,
shape files (shp), etc.

GeoDjango Tutorial provides all the steps to get it done.

https://docs.djangoproject.com/en/dev/ref/contrib/gis/tutorial/

If you are not familiar with geo concepts, I recommend to take a look at
http://geodjango.org/presentations/

Hope that helps you

Re: GeometryField.geography = True Syntax Help GIS Model

2012-11-02 Thread JJ Zolper 
Wait so does anyone know how to do this?

I posted this a long time ago.

How do I define a geography field? I need a geography column so I can 
perform geographic queries on it and the documentation doesn't give me 
a definitive way on how to do it.

Would it be like:

city = models.CharField(max_length=50, GeometryField.geography = true)

???

GeometryField.geography = True Syntax Help GIS Model

Hello everyone,

So I've decided for my GeoDjango application I want WGS84 along with a 
geography database column, rather than geometry.

I was reading here:

GeometryField.geography

If set to True, this option will create a database column of type 
geography, rather than geometry. Please refer to the geography 
type
 section 
below for more details.


that to set up a new column as geography I had to 
set GeometryField.geography = True.

where to properly place this line?

Here is the model.py file I am working on. If you could tell me where to
