Question

如果我制作了一组像这样的代码......

object_data = {}
object = Object.objects.all()
        for o in object:
            ratings = ObjectRating.objects.filter(recipe=r)
            counter = 0
            ratings_sum = 0

            for s in ratings:
                counter += 1
                ratings_sum += s.rating

            rating_average = ratings_sum / counter

            object_data[`o.id`] = (o, rating_average,)


        data = {
            'search_by' : search_by,
            'object' : object_data
        }

如果我将数据字典传递给页面（render_to_response(page, data, context_instance=RequestContext(request))），我如何从模板中的元组的两个部分获取数据。

这就是我认为我必须这样做的方式......

{% for o in object %}
       <tr><td>{{ o.0.name }}</td><td>{{ o.0.description }}</td><td>{{ o.0.other_col }}</td><td>{{ o.0.another_col }}</td><td>{{ o.1 }}</td></tr>
{% endfor %}

这让我感到疯狂，任何见解都会有所帮助。这是Django 1.6（我知道我需要继续前进，所以在你的回答中不要提及）。

Answer 1

为什么不将rating_average作为属性添加到object？

for o in object:
    ... # calculate rating average for this object
    o.rating_average = ratings_sum / counter

data = {
        'search_by' : search_by,
        'object' : object
    }

{% for o in object %}
   <tr><td>{{ o.name }}</td>
       <td>{{ o.description }}</td>
       <td>{{ o.other_col }}</td>
       <td>{{ o.another_col }}</td>
       <td>{{ o.rating_average }}</td>
   </tr>
{% endfor %}

就像这个例子：

class HomeView(generic.TemplateView):
    template_name = '_layouts/index.html'
    def get_context_data(self, **kwargs):
        context = super(HomeView, self).get_context_data(**kwargs)
        mydict = {'wat': 'coo'}
        context['mydict'] = mydict
        return context

模板：

{% for key, value in mydict.items %}
  {{ key }} : {{ value }}
{% endfor %}

Django将元组字典传递给模板
