Question

我关注this tutorial。它在我的视图函数中显示错误

类型错误：无法将Geoqueryset对象隐式转换为str

我的观看功能是

def index(request):
    'Display map'
    waypoints = WayPoint.objects.order_by('name')
    return render_to_response('waypoints/index.html', {
        'title': 'Waypoints Tutorial',
        'waypoints': waypoints,
        'content': render_to_string('waypoints/waypoints.html', {'waypoints': waypoints}),
    })

在最后一行显示错误

内容＆＃39;：render_to_string（＆＃39; waypoints / waypoints.html＆＃39;，{＆＃39;航路点＆＃39;：航路点}）

我的waypoints.html是

{% for waypoint in waypoints %}
    <div id="{{waypoint.id}}" class="waypoint">
        {{ waypoint.name }} ({{waypoint.geometry.y}} , {{waypoint.geometry.x }})
    </div>
{% endfor %}
