Question

我想检查message tag是否为INFO？

如何在模板文件中检查？

我尝试了这个，但它不起作用：

{% if messages %}
    <ul>
        {% for message in messages %}
            <li>
                {% if message.tag == "INFO" %}
                    {{ message }}
                {% endif %}
            </li>
        {% endfor %}
    </ul>
{% endif %}

我甚至尝试了其他组合，例如message.tag.info == "INFO"等，但它们似乎没有用。检查它的正确方法是什么？

Answer 1

使用bootstrap

{% block messages %}
    {% if messages %}
        {% for message in messages %}
            <div class="alert alert-{{ message.tags }}">  <!-- singular -->
                <a class="close" data-dismiss="alert">×</a>
                {{ message|safe }}
            </div>
        {% endfor %}
    {% endif %}
{% endblock %}

所以你正在寻找{{ message.tags }}

在这里您可以使用哪种类型的标签来检查 html 使用单引号而不是双引号它会出错。

{% if message.tags == 'error' %}

Django消息模板标签检查
