django - 分页返回错误的对象(不可迭代？)

Question

我试图返回分页对象，然后遍历它们。看起来很简单。不过，显然我错过了一些东西。你能发现错误吗？

风景:

def thumbnails(request):
    page = request.GET.get('page', 1)
    album = request.GET.get('a', None )

    if (album):
        objects = Album_Photos.objects.filter(id=album)
    else:
        objects = None

    if (objects):
        paginator = Paginator(objects, 25)

    try:
        photos = paginator.page(page)
    except PageNotAnInteger:
        photos = paginator.page(1)
    except EmptyPage:
        photos = None #paginator.page(paginator.num_pages)

    return render_to_response('photos/thumbnails.html', {'photos': photos}, context_instance = RequestContext(request))

模板:

{% if photos %}
    {% for photo in photos %}
        <img src="{{photo.original.url}}">
    {% endfor %}
{%endif%}

错误:

TemplateSyntaxError at /photos/thumbnails/
Caught TypeError while rendering: 'Page' object is not iterable

1 {% if photos %}
2   {% for photo in photos %}
3       <img src="{{photo.original.url}}">
4   {% endfor %}
5 {%endif%}

好吧，与 Django 文档中的示例(至少在我的情况下)不同，您必须将 .object_list 附加到该 Page 对象。

{% if photos %}
    {% for photo in photos.object_list %}
        <img src="{{photo.original.url}}">
    {% endfor %}
{%endif%}
