我似乎无法获得Python字典在HTML模板中输出其值.
以下代码仅打印一个空的select元素.

main.py：

feeds = {'feed1' : 'http://test1.xml',
         'feed2' : 'http://test2.xml'}

template_values = {'movieFeeds': feeds}

self.response.out.write(template.render(temp, template_values))

index.html：

<select>
  {% for (key,value) in movieFeeds.items %}
  <option value="{{value}}">{{key}}</option>
  {% endfor %}
</select>

将其更改为以下代码不会输出密钥：

for key in movieFeeds

有什么想法我要去哪里吗？

编辑：

新代码：

{% for (key,value) in movieFeeds.items() %}
  <option value="{{key}}">{{key}}</option>
{% endfor %}

错误：

解决方法:

您无法在Django 0.96中执行{％为key.data.items％中的值}.
试试这个代替：

{% for item in movieFeeds.items %}
     <option value="{{ item.0 }}">{{ item.1 }}</option>   
{% endfor %}
