Question

我怎样才能获得以下集合并在其中迭代它 django模板？

[('Foo Key', [{'lname': 'Bar', 'fname': 'Foo'}])]

请注意，上面的示例要小得多，只是为了简单起见。如果我们需要完全扩展的集合，例如，如果大小很重要，我可以更新这篇文章。

我最近的成功尝试如下所述。

{% for key0, value0 in data %}
    <tr>
        <td> key0 {{ key0 }}:</td>
        <td> value0 {{ value0 }} </td>
    </tr>

    <p> {% for value1 in value0 %}
        <td> {{ value1 }}</td>
    {% endfor %}
    </p>

{% endfor %}

这将使我得到以下输出。

Foo Key {＆＃39; lname＆＃39;：＆＃39; Bar＆＃39;，＆＃39; fname＆＃39;：＆＃39; Foo＆＃39;}

我似乎无法得到＆＃39; Bar＆＃39;或者＆＃39; Foo＆＃39;出来的。

其他一些背景以下是生成数据的视图

from django.shortcuts import render
from .models import Person, PersonMeta    

# Create your views here.
def thanks(request):
    return render(request, 'thanks.html')    


from .forms import NameForm


def home(request):
    # if this is a POST request we need to process the form data
    if request.method == 'POST':
        # create a form instance and populate it with data from the request:
        form = NameForm(request.POST)
        # check whether it's valid:
        if form.is_valid():
            data = {}
            # process the data in form.cleaned_data as required
            currentUser = request.user
            person = Person.objects.create(first_name=currentUser.first_name, last_name=currentUser.last_name,
                                           nickname=form.cleaned_data['nickname'])
            # getting front loaded personMeta
            personDetails = PersonMeta.objects.filter(frontLoaded_first_name=currentUser.first_name,frontLoaded_last_name=currentUser.last_name).values()

            # setting key
            currUserKey = "{0} {1}".format(currentUser.first_name, currentUser.last_name)

            # if person details is not false
            # this if may not have to be here. 
            if (personDetails):
                data[currUserKey] = personDetails    

                # redirect to a new URL:
        return render(request, 'signUp.html', {'data': sorted(data.items())})    

    # if a GET (or any other method) we'll create a blank form
    #
    else:
        form = NameForm()    

        return render(request, 'home.html', {'form': form})

dict中有一个list，这是另一个tuple内list的第二个值：

[('Foo Key', [{'lname': 'Bar', 'fname': 'Foo'}])]

所以我们走了：

{% for tuple in data %}
    <p>Tuple key: {{ tuple.0 }}</p>
    {% for key, value in tuple.1.0.items %}
        <p>Dict key, value: {{ key }}: {{ value }}</p>
    {% endfor %}
{% endfor %}

如何在django模板中迭代这个特定数据（列表中的dict，这是另一个列表中元组的第二个值）？
