操作

示例 admin.py

@admin.register(Test)
class TestAdmin(admin.ModelAdmin):

def save_model(self, request, obj, form, change):
    temp1 = 'Yudelei.com'
    temp2 = 'Author: Shanks'
    hhf = '\n'
    html = temp1 + hhf + temp2
    obj.html = html
    obj.save()

重写/修改 fieldset.html

PyCharm -> ctrl + shift + f (全局搜索) -> field.is_readonly -> 找到位于

venv\Lib\site-packages\simpleui\templates\admin\includes\fieldset.html

的如下代码：

{% if field.is_readonly %}
    <div class="readonly"> {{ field.contents }} </div>
{% else %}
    {{ field.field }}
{% endif %}

修改为：

{% if field.is_readonly %}
    <div class="readonly"> {{ field.contents|linebreaksbr }} </div>
{% else %}
    {{ field.field }}
{% endif %}
