{django-tables} Caught NameError while rendering: global name 'name' is not defined

Please why am I get the following error:

Caught NameError while rendering: global name 'name' is not defined.

Initially I did not receive this sort of error, it just surfaced all off a sudden. I restored my app to the state where everything worked and I'm still getting the same error.

                        <div class="actions">

In my template file:

{% load humanize %}
{% load tables %}
{% load pagination_tags %}
{% autopaginate rows 2 %}
{% for row in table.rows %}
<tr class="{% cycle 'odd' 'even' %}">
{% for value in row %}
<td class="table-data">{{ value }}<td>
{% endfor %}
</tr>
{% endfor %}

When i remove the above code from开发者_如何学运维 my template the error goes away but table rows are not displayed.

code from views.py

class TransactionReport(tables.ModelTable):
    identifier = tables.Column(sortable=False, visible=False)
    created = tables.Column(sortable=True, visible=True)

    @classmethod
    def get_reports_paid(self, object, req):
        return TransactionReport(object, order_by=req)

    class Meta:  
        model = Transaction


    @login_required
    def display_reports(request):
        logger = logging.getLogger(__name__)
        dataqs = Transaction.objects.filter(paid="TRUE")
        req = request.GET.get('sort', 'created')
        tx = TransactionReport().get_reports_paid(dataqs, req)

        return render_to_response('webapp/reports.html', {'table': tx, 'rows' : tx.rows})

Any suggestions please.

Thanks
