Question

例如，在触发管理员操作之后，如何添加新行。

from django.contrib import messages

messages.error(request, 'This is a line \n and this is another line')

我也尝试了html标记，但是没有用。

Answer 1

我认为您需要覆盖admin.base模板的一部分

为了遵守换行符。有内置的模板标签linebreaksbr

base_site.html中的覆盖块为：

<!-- The path and name for this file should be "templates/admin/base_site.html". -->
<!-- It overrides the original admin template and will be picked up by all of its children. -->
<!-- This template override has been verified for Django 1.11 and 2.0. -->

{% extends "admin/base_site.html" %}

{% block messages %}
    {% if messages %}
    <ul class="messagelist">{% for message in messages %}
      {# added linebreaksbr here #}
      <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message|capfirst|linebreaksbr }}</li>
    {% endfor %}</ul>
    {% endif %}
{% endblock messages %}
