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.
Regards
Chris

You can try saving the data as
latitude=models.DecimalField(max_digits=7,decimal_places=4).Same for the
longitude field.Here the max_digits takes into account both decimal and
non-decimal places.All the data can be given in string form as it will be
automatically converted to proper format as specified in your models for
storing in database. 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

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
