Templates don't process data.

Do you mean to use a form?

Hi,

Are you meant form submission? if Yes...

Submit your form and get all submitted values in view method using request.POST/GET.copy()

i had an array of coordinated tht i got from a dictionary via a view in views.py

now i used a javascript function in the template called index.html to find coordinates that are in a polygon

and i want to send the list of those coordinates back to the view so that i ca save them into a table.

views.py

# Import django modules
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render_to_response
from django.template import RequestContext
from django.template.loader import render_to_string
from django.core.urlresolvers import reverse
from django.contrib.gis.geos import Point
from django.contrib.gis.gdal import DataSource
# Import system modules
import simplejson
import itertools
import tempfile
import os
import MySQLdb
# Import custom modules
from mochudimaps.locations.models import Location
from mochudimaps import settings


def index(request):
    'Display map'
    locations = Location.objects.order_by('name')
    return render_to_response('locations/index.html', {
    'locations': locations,
        'content': render_to_string('locations/locations.html', {'locations': locations}),
        }, context_instance=RequestContext(request))

i used django template language to access value from my models in the database which are coordinates the using javascript i wrote a function that give a list of coordinates that are within a polygon in a map.

now i want to send that list back to a view or view then database table

Hi,

like Stephen mentioned you can use a post request [1] for that.

The field 'data' could contain the list of coordinates in an array [2]
with the name 'coords' which itself can be accessed within the view via
request.POST['coords'].

One of many examples you can find here:
http://stackoverflow.com/questions/5457568/retrieving-post-data-from-jquery-in-django-without-a-form

[1] http://api.jquery.com/jQuery.post/
[2] http://de.selfhtml.org/javascript/objekte/array.htm

Good luck,
