Hi Jay, I am no Geo expert but if you use the CharField then you can specify N/E/S/W (North/East/South/West) or + and - to control latitude & longitude. With the DecimalField you can only use the + and -.
BTW, Marty Alchin's book Pro Django (Chapter 5 page 118), shows a nice example to validate user input for latitude & longitude. He actually use the DecimalField and extends it with a clean method, checking that latitude values to fall in -90 to 90 & longitude values to fall in -180 to 180.

I guess you will be using some criteria to extract data from the database.......so,code can look like list_of_XYZ()=XYZ.objects.filter(criteria) for i in list_of_XYZ: i.latitude,i.longitude ,i.zoomlevel On Tue, Apr 5, 2011 at 1:45 AM, jay K. <jay.developer2...@gmail.com<mailto:jay.developer2...@gmail.com>> wrote: Hello, I got a couple of fields from a model I want to use so the models.py looks like this class XZY(): latitude = models.CharField(....) longitude = models.CharField(.....) zoomlevel = models.CharField(....) I want to retrieve the data inside latitude, longitude and zoomlevel to be able to create a static map for different locations, using google maps How can I retrieve the fields data? thanks -- You received this message because you are subscribed to the Google Groups "Django users" group.
