Django-显示嵌套在html模板列表中的字典中的值

Question

I have the followed class-based views in my views.py file:

class HomeView(TemplateView):
    template_name = 'annual_means/home.html'

    site_list = AnnualMean.objects.values("site").distinct()

    def get_context_data(self, **kwargs):
        context = super(HomeView, self).get_context_data(**kwargs)
        context['sites'] = AnnualMean.objects.values("site").distinct()
        return context

At the top of my html template, just for testing this out, I have {{sites}} and it is displaying:

Below, I have the following html code:

{% for value in sites %}
    <li>{{value}}</li>
{% endfor %}   

And it lists all the key:value pairs as shown above, eg {'site': 'Belfast Centre'}, instead of just the values. I assume this is due to the dictionary in the QuerySet being nested within a list. Is there a way I can return just the a dictionary or otherwise get around this problem?

Answer 1

I think you should use this as :

{% for value in sites %}
    <li>{{value.site}}</li>
{% endfor %}   

It will now print the values in list

Answer 2

You can access a key in a dictionary using the dot notation :

Dictionary lookup, attribute lookup and list-index lookups are implemented with a dot notation:

  {{ my_dict.key }} {{ my_object.attribute }} {{ my_list.0 }} 

For your code, that would be:

{% for value in sites %}
    <li>{{value.site}}</li>
{% endfor %}
