如何正确解压django HTML模板中的嵌套字典？

data = {
    'user': {
        'name': 'John Doe',
        'age': 30,
        'address': {
            'city': 'New York',
            'zip': '10001'
        }
    }
}

{% with user_name=data.user.name user_age=data.user.age user_city=data.user.address.city %}
    <p>Name: {{ user_name }}</p>
    <p>Age: {{ user_age }}</p>
    <p>City: {{ user_city }}</p>
{% endwith %}

{% for key, value in data.items %}
    {% if key == 'user' %}
        <p>Name: {{ value.name }}</p>
        <p>Age: {{ value.age }}</p>
        {% for addr_key, addr_value in value.address.items %}
            <p>{{ addr_key }}: {{ addr_value }}</p>
        {% endfor %}
    {% endif %}
{% endfor %}

<p>City: {{ data.user.address.city|default:"Unknown" }}</p>
