..... worked this morning and all last week  now gives this error:

Request Method:	GET
Request URL:	http://10.0.0.102:8080/sto/

Hi am plugging away at learning Django and have done well so far (thanks to great documentation and Stackoverflow) but I have run into a problem that i cant seem to figure out.


I have a model that refers to another model that refers to another model.

example :

Class ServiceOrder
    id -integer
   customer location = foreign key to location

def __str__(self):
        return self.stid

class Location:
   id -integer
   address -char
   customer- foreign key to customer

        q= '%s %s %s %s ' %(self.addr1, self.addr2, self.city, self.country)
        return unicode(q).encode('utf-8')

Class Customer
    id=int
    name- char
return unicode(self).encode('utf-8')

I have a template that lists the service orders view is below:


def serviceorder_list(request, status = 'Closed'):
        ist = ServiceOrder.objects.filter(status = status, stid__lte=20239).select_related('customer_location__customer')    #stid__lte 20239 to fix database error ... i have existing data that has its own issues...
        count = order_list.count()
        context ={'list': sto_list, 'count': count}
     
        return render(request, 'order/listview.html', context)


in my listview.html

{% for item  in list %}
            {% if item.project %}
            <td><a href="{{ item.stid }}">{{item.stid}}</a></td>
            <td>{{item.project}}</td>
            <td>{{item.customer_location.name}}</td>  ---------------------- 2 questions here  1) it throws an error on customer names that have accents etc ... 
            <td>{{item.notes}}</td>                                                                              2) i am confused about how to properly referenece the customer name or anything else that is not in the Service order  model.                   
            <td>{{item.person_responsible}}</td>
            <td>{{item.entrydate|date:'M-d-y'}}</td>
          <td>{{item.status}}</td>
          <td>{{item.billing}}</td> 
          </tr>


I have read the docs many times and the more i read the more i know that i don't know ... any help would be appreciated


Thanks
