如何覆盖Django admin的观点？

I want to add an upload button to the default Django admin, as shown below:

我想在默认的Django管理员中添加一个上传按钮，如下所示：

To do so I overrode the admin/index.html template to add the button, but how can I override the admin view in order to process it?

为此，我重写了admin / index.html模板以添加按钮，但是如何覆盖管理视图以便处理它？

What I want to achieve is to display a success message, or the error message, once the file is uploaded.

我想要实现的是在上传文件后显示成功消息或错误消息。

The index view is on the AdminSite instance. To override it, you'll have to create a custom AdminSite subclass (i.e., not using django.contrib.admin.site anymore):

索引视图位于AdminSite实例上。要覆盖它，您必须创建一个自定义AdminSite子类（即，不再使用django.contrib.admin.site）：

from django.contrib.admin import AdminSite
from django.views.decorators.cache import never_cache

class MyAdminSite(AdminSite):
    @never_cache
    def index(self, request, extra_context=None):
        # do stuff

You might want to reference the original method at: https://github.com/django/django/blob/1.4.1/django/contrib/admin/sites.py

您可能希望在以下位置引用原始方法：https：//github.com/django/django/blob/1.4.1/django/contrib/admin/sites.py

Then, you create an instance of this class, and use this instance, rather than admin.site to register your models.

然后，您创建此类的实例，并使用此实例而不是admin.site来注册您的模型。

admin_site = MyAdminSite()

Then, later:

然后，后来：

from somewhere import admin_site

class MyModelAdmin(ModelAdmin):
    ...

admin_site.register(MyModel, MyModelAdmin)
