如何在Django Admin中向用户更改页添加说明

# admin.py

from django.contrib import admin
from django.template.response import TemplateResponse

from .models import YourModel

class YourModelAdmin(admin.ModelAdmin):
    def change_view(self, request, object_id, form_url='', extra_context=None):
        extra_context = extra_context or {}
        extra_context['description'] = "这是你的自定义说明内容"
        return super().change_view(
            request, object_id, form_url, extra_context=extra_context,
        )

    def get_changelist(self, request, **kwargs):
        self.changelist_template = 'admin/change_list.html'
        return super().get_changelist(request, **kwargs)

admin.site.register(YourModel, YourModelAdmin)

<!-- change_form.html -->

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

{% block extrahead %}
{{ block.super }}
<style>
    .description {
        color: #999;
        font-size: 14px;
        margin-top: 10px;
    }
</style>
{% endblock %}

{% block object-tools-items %}
{{ block.super }}
<div class="description">
    {{ description }}
</div>
{% endblock %}
